The Roman Villa in Sant’Imbenia. Documentation, Conservation and Museum Display of the artifacts found during the 1994-2005 excavations 

The story of the conservation, restoration and museum display of materials from the Roman Villa of Sant’Imbenia is narrated by the project’s key players. The decorative scheme of a space on the second floor of the opulent Roman domus was reconstructed thanks to a thorough investigation into the materials’ nature and history. Marble, stucco and fresco fragments were restored and reassembled to form opus sectile floors, wall veneer, decorative reliefs and ceilings with frescoed cupolae. The interpretative reconstruction, now on display in the Museo della Città in Alghero, is presented as the project’s logical conclusion. The curatorial choice of illuminating the reconstructed room with a window that opens onto the Villa’s original landscape marks the will to leave an open door to future archaeological investigations.

The conservation of the 6th century mosaic of the Transfiguration in the Monastery of Saint Catherine in the Sinai


Nardi, R. and Zizola, C.

2015


The mosaic of the Transfiguration covers a surface of 46 m2 in the basilica of the Monastery of Saint Catherine's in Sinai. Done in the 6th century at the behest of the emperor Justinian, it has a rich chromatic range of glass paste, glass, gold and silver tesserae and tesserae in stone. The mosaic is a jewel of early Byzantine art. Over the centuries, it has suffered extensive damage due to earthquakes and intense visitation by pilgrims from all corners of the world. Some of the signs of deterioration were detachment of the preparatory layer from the wall, bulges in the mosaic surface, and lacunae (gaps) in the tesselatum. The area of Christ was so badly decayed that the mosaic was close to collapse, as an article of Kurt Weizman on the National Geographic reported in 1964. These problems led the monastic community to undertake a delicate program of consolidating and conserving the mosaic, and the CCA, Center for Archaeological Conservation, Rome, was asked to do the restoration. The work began in 2005, thanks to financing from the Emir of Qatar, Sheik Hamad bin Khalifa al Thani, following a project plan the CCA developed in 2001 for the Getty Conservation Institute (GCI).

La calce: utilizzare un materiale antico a garanzia del futuro


Costanzi Cobau, A.

2013


La calce è stata usata fin dall’antichità per la realizzazione di edifici, soffitti, di rivestimenti parietali, di pavimenti. Il loro stato di conservazione nel tempo offre l’empirica sicurezza che si tratti di un materiale in grado di invecchiare bene. Ciononostante, in una bibliografia della conservazione, la descrizione dell’uso della calce come materiale di restauro compare sempre in parti marginali. In questo articolo si vuole presentare l’utilizzo della calce aerea (grassello) in diverse miscele e soluzioni impiegate nel corso di trenta anni di cantieri di restauro eseguiti con il CCA, Centro di Conservazione Archeologica, in Italia ed all’estero.

Site Conservation during the Rescue Excavations


Nardi, R. and Schneider, K.

2013


Zeugma has been affected by a major regional hydroelectric project involving the construction of several dams on the Euphrates River in southern east Turkey. During the summer of 2000, the reservoir for the Birecik Dam flooded 30 per cent of the ancient city of Zeugma and the entire ancient city of Apamea on the opposite bank. This chapter reports on the conservation carried out at Zeugma by the Centro di Conservazione Archeologica – Roma (CCA) from June to October 2000, as well as conservation work carried out on finds and maintenance of the archaeological site of Zeugma in a three-year period following the impoundment of the Birecik Dam.

Conservation of the mosaic of the Transfiguration at Saint Catherine's


Nardi, R. and Zizola, C.

2013


The Monastery of St. Catherine on Mount Sinai was built under the Byzantine emperor Justinian in the sixth century, on a site that had been venerated long before as the place where Moses encountered God in the form of the burning bush (Exodus 3:1-10). In the fourth century AD, a small shrine had stood there, built at the request of the Empress Helena, the mother of Costantine. For centuries, the high number of pilgrims, monks and hermits who had come to honor this holy place had endured the uninterrupted harassment of raiders and the harsh circumstances of the desert. This paper describes the conservation intervention of the mosaic of the Transfiguration, located in the apse of the basilica of the Monastery of St. Catherine's, as well as the methodological choices that have led to the conservation strategy that was adopted. As with all works of art, mosaics do not enjoy eternal life because of their very nature; to the contrary, they are fragile and need care and attention. Alarmed by clear signs of decay in the mosaic, the monastic community of St. Catherine's embarked on a conservation program and entrusted the work to the CCA, Centro di Conservazione Archeologica. The treatment, which began in November 2005, has been long, delicate and complex.

2011


The Monastery of St. Catherine on Mount Sinai was built under the Byzantine emperor Justinian in the sixth century AD, on a site that had been venerated long before as the place where Moses encountered God in the form of the burning bush (Exodus 3:1-10). For centuries, the high number of pilgrims, monks and hermits who had come to honor this holy place had endured the uninterrupted harassment of raiders and the harsh circumstances of the desert. Located at the height of 1.500 meters in a ravine at the foot of the Gebel Musa, where Moses received the Tables of the Law, the massive, fortfied walls of the monastery both enclose and protect the life of the monks who live there, their daily routine governed by the ringing of the church bells that call them to prayer from sunrise to sunset, according to the monastic traditions of the Greek Orthodox rite. The buildings within the walls form an ancient city, with manifold architectural styles from various ages. Only a short distance from the church's bell tower, stands the minaret of a small mosque: evidence of the peaceful coexistence between religions and peoples.

The text presents the method used for the treatment of gaps in the mosaic of the Transfiguration in St. Catherine's Monastery in Sinai, conserved by CCA in the years 2005-2010. While recognizing this issue a relatively minor role in the hierarchy of the aspects that make up a complex program such as the one implemented in Santa Caterina, the debate that preceded the decision and the importance of the monument, however, make a case that could take a sample value (positive or negative) within a dialectical methodology that has left on this issue and rivers and mountains of pages of words.

Mosaic Conservation: Fifty Years of Modern Practice


de Guichen, G. and Nardi, R.

2008


Mosaic conservation practice went through a significant evolution in the past decades. Fifty years ago mosaics were considered as single objects, without a context, and interventions were carried out without adequate planning. Few options were considered in conservation strategies, and detachment was basically the only options taken into consideration. Professionals working on mosaics were essentially craftsmen, workmen and builders; the materials used were limited to cement, gypsum and glues. This presentation debates the change of philosophy and practice of mosaic conservation that shaped the current state of the art in the profession.

Conservation for presentation: a key for protecting monuments


Nardi, R.

2008


Abandonment, neglect, poor planning or inadequate presentation of cultural heritage are common occurrences. In some cases, the only way to prevent destruction and abandonment is to undertake treatment specifically designed for public consumption, with the aim of recovering forgotten or undervalued heritage. Accepting this premise, in certain circumstances conservation treatment suggests technical solutions that are closer to restoration than conservation. This type of situation has occurred several times in the course of the activities of the CCA, Centro di Conservazione Archeologica, and has been approached as described in the article. The interventions were carried out in Israel in the Large Baths and Liscat Hamefaked in Masada, and in Radà, Yemen, in the Madrasa Amiriya. A case still in progress, the conservation of gigantic stone statues from the tenth century BC from Cabras, Sardinia, Italy, concludes the article.

The Legacy of Nora, Sardinia: a project for the Conservation, Restoration and Maintenance of Mosaics


Zizola C.

2008


This paper describes the conservation and maintenance project of the 720 m2 floor mosaics of the archaeological site of Nora, Sardinia, designed by CCA, Centro di Conservazione Archeologica, in 2002 for the Soprintendenza Archeologica of Cagliari. Nora is a site with high number of visitors and difficult climatic conditions due to the marine environment. The 2002 project was based on an analysis of the state of conservation of the mosaics and of the performance of the previous restorations and reburials. The result was a detailed technical program for treating the mosaics and a general plan for the ordinary maintenance of the mosaics and site. This project today forms the basis for the current management plan of the Soprintendenza for Nora. The present paper compares the results of previous restorations and reburials with more recent strategies, provides a time estimate for technical treatments and presents the ordinary maintenance program that includes a list of the operations.

Mosaic Conservation. Fifty Years of Modern Practice


De Guichen, G. and Nardi, R.

2006


Mosaics conservation is a practice as old as mosaic-making itself. We can see today ancient mosaics showing patches made as a maintenance practice when the floors were still in use. We are also aware that restoration was an art widely used in past centuries by antiquarians. We might also refer to brilliant examples of restorations implemented during the first decades of the 20th century.

Madrasa Amiriya. The Conservation of the Mural Paintings


Al Radi, S., Nardi, R. and Zizola, C.

2005


The Amiriya Madrasa of Radà is one of the most important and significant monuments of Yemen. Constructed in 1504, it represents a jewel of Islamic art and architecture with its three built levels, 600 mof tempera wall paintings and extensive, elaborate plaster decorations. It is notable for the balance achieved between the size of the structures and the refinement of the details. In 2000, the CCA, Centro di Conservazione Archeologica, was asked to restore the wall paintings that decorate the Prayer Hall, as well as to train six Yemeni technicians how to maintain the wall paintings. Published by the CCA in Arabic, English and Italian at the end of the treatment, the book describes the Amiriya Project, documents the work phases, analyses the original working process and the final results obtained in the conservation of the cycle of wall paintings that adorn the Prayer Hall. The volume is accompanied by a catalogue of the decorative elements of the cycle and technical forms illustrating types of deterioration.

La conservazione e il restauro delle pitture murali della Madrasa Amiriya, Radà, Yemen


Zizola, C.

2005


This article describes in Italian the restoration of the wall paintings of the Amirya madrasa, one of the most significant ancient structures of the city of Radà, in the north of Yemen. The building was commissioned by the sultan Amir bin Abd al-Wahhab of the Tahirid Dinasty, in 1504. Richly decorated on the interior, the building contains elaborate and brightly colored tempera wall paintings in the prayer hall. They were painted on gypsum plaster and are surrounded by an intricately carved stucco frieze. The paintings cover most of the walls and fill all six domes, some 600 mof surface. They represent a unique example of Islamic decorative motifs, and act as a synthesis of 500 years of wall-painting tradition in Yemen. The restoration treatment of the paintings in the prayer hall, performed by the CCA, Centro di Conservazione Archeologica, was the final phase of a complex program of recovery and conservation of the monument, which had been heavily damaged by earthquakes and 500 years of neglect. It was carried out completely with traditional techniques and materials and with great ethical care in a joint program directed by Prof. Selma al-Radi, and financed by the governments of Italy, the Netherlands and Yemen.

In September 2001, a restoration worksite was opened in the Salone of the Palazzo Nuovo of the Capitoline Museums to treat two Roman statues from Hadrian's Villa: the Old Centaur and the Young Centaur. During the restoration, performed by the CCA, Centro di Conservazione Archeologica, the Salone of the museum was not closed to the public. We seized the opportunity to show all the phases of the work: a platform was equipped for the conservators to work on, and various cultural activities were organized at the same time in order to foster understanding of the treatment. The name "Open for Restoration" was given to the worksite and those related initiatives. This paper describes in Italian the initiatives organized during this conservation program.

Zeugma: l’intervento di conservazione, 2000-2003


Nardi, R.

2003


Zeugma è il nome dato a due città, Apamea e Seleucia, fondate da Seleuco I (312-281 a.C.), sulle rive opposte del fiume Eufrate nel sud est dell’Anatolia, Turchia. Il sito, individuato nel 1970 dall’archeologo tedesco Jorg Wagner, è stato oggetto negli anni ottanta e novanta di alcune indagini archeologiche, condotte da David Kennedy dell’Università di Western Australia, da Catherine Abadie-Reynal dell’Università di La Rochelle e dal Ministero della Cultura della Turchia - Museo di Gaziantep. Negli stessi anni, Zeugma si è trovata coinvolta nel grande progetto di sfruttamento idroelettrico della regione, che ha comportato la costruzione di alcune dighe. Una di queste, la diga di Birecick, con il suo invaso, avrebbe durante l’estate del 2000 sommerso il 30% della superficie dell’antica città. A maggio del 2000, grazie anche agli eccezionali ritrovamenti di reperti mobili e di due ville riccamente decorate da affreschi e mosaici, gli sforzi di un editore di un giornale di Gaziantep riescono a far breccia nell’attenzione della stampa internazionale e la richiesta di aiuto per Zeugma inizia a fare rapidamente il giro del mondo. A raccogliere l’appello è il Packard Humanities Institute (PHI), con sede in California, che mette immediatamente a disposizione le risorse economiche ed umane necessarie ad organizzare e coordinare insieme al Ministero della Cultura della Turchia un piano di azione immediata.

Il restauro conservativo del mosaico di Quintus Calpurnius Eutyches-Zeugma


Zizola, C.

2003


In October 2002 at Zeugma, Turkey, due to an exceptional lowering of the water level of the artificial lake for technical reasons by the direction of the Birecik dam, one of the largest mosaics ever found there came to light. Being in an unexcavated area, it had not been found during investigations in prior years.  It is a figured polychrome mosaic of 75 m2. According to local accounts, it had suffered from an attempted theft in the 1970s, which had succeeded only in part, as discovered later on the site. Two figured panels in the center of the pavement are surrounded by complex, elaborate geometric designs. The mosaic's name derives from one of the Greek inscriptions bearing the name of Quintus Calpurnius Eutyches. This article illustrates the technical aspects of the detachment and conservation treatment of the mosaic.

The ancient town of Zeugma on the river Euphrates in South Anatolia, Turkey, was partially inundated during the year 2000 by the new Birecik Dam. In this context, the Packard Humanities Institute organized in co-ordination with the Turkish Authorities an international program for emergency archaeological rescue operations, based on excavation, and on site conservation. This paper reports the operations implemented by 25 professional conservators from CCA, Centro di Conservazione Archeologica, in charge of the conservation management. Field assistance to the archaeologists, first aid during excavation, preventive conservation, protection, reburial and "risks mitigation" of the flooded area are some of the operations that are presented. A two-year maintenance program is also described.

La conservazione e il restauro dei mosaici di Zeugma


Nardi, R.

2002


The ancient city of Zeugma on the banks of the Euphrates in Turkey, was partially flooded in 2000 by the new Birecik dam. In May of 2000, the Packard Humanities Institute (PHI), in coordination with authorities of the Turkish Ministry of Culture, initiated an international rescue program based on a "targeted" archaeological investigation and a plan for conservation in situ: the Zeugma Archaeological Project (ZAP 2000); this was an emergency operation intended to increase topographical knowledge of the city and safeguard the finds before total flooding. The program also involved the restoration of everything that had been excavated and removed from Zeugma in the course of previous digs. The CCA, Centro di Conservazione Archeologica, was asked to plan and implement the conservation and restoration program. Starting in July 2000 through November of the same year, a group of 25 professional Italian and Turkish conservators carried out the program during and after the archaeological excavation. Subsequently, the same group worked on the restoration of 800 m2 of mosaics removed from Zeugma. The volume describes the various operations performed, with particular reference to the mosaics.

Conservation and Maintenance of Floor Mosaics in Archaeological Areas


Zizola, C.

2002


In recent years, in the field of conservation and protection of excavation areas, there has been a growing conviction that preventive conservation – especially maintenance – is one of the most suitable tools for effective and extensive conservation, as it is the most practicable in cost-benefit terms. This discipline, which has only recently appeared on the conservation horizon, has its origins in antiquity. It offers a valid reply to the disproportion between the exigencies of conserving an ever-increasing amount of heritage and the growing demand for access by new generations of visitors. In this article, techniques for the conservation and maintenance of mosaics in situ in archaeological areas will be discussed. This will be done by revisiting the sources and describing the modern techniques, proposing a methodological approach and supplying evaluations of the techniques, costs and results obtained. Archaeological mosaics displayed in museums, albeit numerous and not without maintenance problems themselves, will not be discussed, as they call for different conservation considerations and treatment techniques.

Per una carta della conservazione del mosaico


Nardi, R.

2001


Da più di 40 anni gli specialisti della conservazione dei siti archeologici si riuniscono per discutere fatti e temi inerenti il patrimonio. Questo sforzo comune si è concretizzato in pubblicazioni quasi sempre corredate di dichiarazioni conclusive che riportavano linee guida metodologiche e raccomandazioni. Da 25 anni il campo professionale si è arricchito di un nuovo strumento specialistico, the International Committee for the Conservation of Mosaics (ICCM). Questo comitato si riunisce ogni tre anni in un convegno che ha prodotto negli anni una consistente letteratura, oggi strumento fondamentale di riferimento per la professione. Allo stesso tempo, al termine di alcuni di questi incontri sono state redatte delle raccomandazioni metodologiche atte a facilitare il raggiungimento dell'obiettivo comune: la conservazione del mosaico. Allo stesso tempo, la vita quotidiana sul campo degli addetti ai lavori è segnata dalle difficoltà grandi e piccole di tutti i giorni. Prima tra tutti quella della mancanza di un testo unico di riferimento al quale rifarsi in caso di incertezza metodologica o comunque l'assenza di uno strumento utilizzabile come documento nel quale tecniche e metodologie siano codificate. Obiettivo del lavoro qui presentato è quello di produrre una analisi preliminare dei materiali già esistenti sotto forma di "raccomandazioni", e a far nascere una piazza comune in grado di fungere da catalizzatore di un dibattito professionale utile a codificare principi e metodologie e a produrre una carta di riferimento.

Zeugma Archaeological Project 2000 - The Conservation Program


Nardi, R. and Schneider, K.

2001


'Preserving Archaeological Remains in situ?' (PARIS2) conference addressed three main themes: to review recent research; to examine the relative successes and consequences of decisions – especially those taken in the last decade or so – to preserve particular sites in situ; and to try to identify strategic directions for future research into the protection of our cultural heritage. The paper presented by R. Nardi and K. Schneider tells the story of the ancient town of Zeugma on the river Euphrates in South Anatolia, Turkey, when this was partially inundated during the year 2000 by the new Birecik Dam. In this context, the Packard Humanities Institute organized in co-ordination with the Turkish Authorities an international program for emergency archaeological rescue operations, based on excavation and on site conservation. This paper reports the operations implemented during 6 months by 20 professional conservators from Centro di Conservazione Archeologica, CCA, in charge of conservation. Field assistance to the archaeologists, first aid during excavation, preventive conservation, protection, reburial and "risks mitigation" of the area for the flooding, are some of the operations presented.

Archaeological mosaics: from detachment and transport to museums and storerooms to in situ conservation practice


Nardi, R. and Zizola, C.

2001


In the course of a few decades, the discipline of conservation of archaeological mosaics has matured quickly: from detachment and transport to museums and storerooms (done systematically as the only form of safeguard), it has arrived at the theoretical and methodological formulation of in situ conservation, flanked by the development of an approach for damage control. Today, conservation in situ is no longer an experimental field but a well-developed discipline, with a wide range of application, good practice and solid technique. Intervention methods such as detachment and removal of artifacts from the site are seen as urgent remedies to be used, after careful evaluation, only in cases where the risk of loss or destruction cannot otherwise be avoided (risks from theft, urbanization, road works) and when in situ consolidation and conservation have been shown to be ineffective. This paper trace the evolution towards in situ conservation and the application of methodologies infused with respect for history and the nature of the components, with minimum interventions and preventive conservation through various restoration charters, international recommendations and in the professional literature.

Conservation of monuments: where are we going?


Nardi, R.

2000


The end of the millennium and the beginning of another is an opportunity to reflect upon the state of our profession: the conservation of our cultural heritage. This paper looks at the experiences of the Centro di Conservazione Archeologica (CCA), a private firm, active for 15 years on public commission in the conservation of monuments and archaeological sites. Initially, the work of CCA was devoted solely to restoration/conservation, with the use of so-called modern techniques and materials having a significant impact on the original fabric. Today, the materials and techniques used are almost exclusively traditional (in the historic sense) and have minimal impact on the monument. In addition, our present sphere of activity is much wider and, alongside actual conservation work, we are asked to carry out documentation, training courses, maintenance and public information initiatives. Thus we recognize that our profession has finally abandoned the restoration approach for a new path in the direction of preventive conservation. proceedings of a joint conference organized by English Heritage and the United Kingdom Institute for Conservation, London, 20-22 May 1998 / Fidler, John (ed.); Teutonico, Jeanne-Marie (ed.).

Tourism management of archaeological sites within an urban context: a balanced compromise between preventive conservation and cultural use


Nardi, R.

2000


The real emergency today and even more tomorrow, will not be in those sites in the urban environment, known, visited and sometimes also maintained, but in the tens of thousands of sites where decay and destruction are everyday events because they have been abandoned, or because they are poorly managed. Sites that yesterday enjoyed a “a certain oblivion”, but today are entering more and more into the big circuit of so called “cultural tourism”. Everyday cultural property suffers irreversible damage due to the lack of even minimal protective measures. This article presents three initiatives carried out by the Centro di Conservazione Archeologica in the field of training, maintenance and raising awareness. The first initiative is relative to a training programme for site directors, that CCA organised for UNESCO financed by the Italian Ministry of Foreign Affairs. The second initiative is related to the study and application of techniques of maintenance of archaeological structures in sites open to the public. The third and last initiative concerns the raising awareness to themes of fragility of the cultural heritage and its safeguarding. An exhibition entitled “S.O.S. Save Our Sites” made up of 26 panels, divided into three sections, in English and Arabic organised by CCA for the Amman Office of UNESCO is presented.

Going public: a new approach to conservation education


Nardi, R.

1999


Bringing conservation projects out into the open under the eye of public scrutiny is a recent phenomenon that has been taken up by a growing number of museums and heritage sites. The program described here is one of the most ambitious to date and makes clear why such an approach goes well beyond the simple explanation of technical treatments to have a resounding impact on public perception and appreciation of broader heritage questions.

Ostia Antica. Piazzale delle Corporazioni. The maintenance of the mosaic floors


Nardi, R.

1999


In 1998 the Superintendence of Ostia began a program for the conservation, protection and maintenance of monuments with open air mosaic floors. The Termae dei Cisiarii was the first monument to be treated (1994-96). In 1998, with the introduction of a special law for the 2000 Jubilee, a conservation program was created for the Piazzale delle Corporazioni. This program included the maintenance of the floors and indirect measures of protection such as new paths for visitors. Piazzale delle Corporazioni was one of the main squares of Ostia and is still today a key transit node for visitors. The ancient monument now consists of remains of the walls and about 1900 square metres of pavement. Of these, about 1000 sq. metres are mosaic, some in situ, others detached and laid on a cement base during the 1960s. The remainder is reconstructed in cement. This paper presents the maintenance program of all the floors, carried out during June and July 1998. The techniques, time and costs of the treatment, the conception of informing the public as the work progresses and the planned measures for protection and future maintenance are described.

La sensibilizzazione del pubblico per la salvaguardia del patrimonio culturale


Nardi, R.

1999


Il panorama degli interventi di conservazione si è arricchito negli ultimi anni di un nuovo fenomeno: l'apertura dei cantieri al pubblico e la realizzazione di operazioni tecniche "in diretta". Questo fenomeno rappresenta qualcosa di più profondo della semplice apertura fisica di spazi di lavoro e si pone risultati più ambiziosi della semplice "spettacolarizzazione" degli interventi. Il CCA, Centro di Conservazione Archeologica, negli ultimi quindici anni ha aperto i propri cantieri al pubblico ogni qualvolta le condizioni lo permettevano. Questa scelta è stata determinata dalla convinzione che rendendo il pubblico cosciente dei rischi di deperimento che il patrimonio corre quotidianamente e della difficoltà e  dei costi che comporta rimediare a questi rischi, si possa lentamente educarlo al rispetto delle opere (prevenire vandalismo e uso inadeguato) e farlo partecipe alla loro salvaguardia (creare consenso).

The conservation and restoration of the mosaic floor of the Bizantine Church (Western) in the Nabatean town of Mamshit in the Negev desert


Zizola, C.

1999


During 1994 the CCA, Centro di Conservazione Archeologica, carried out the in situ conservation of the mosaic floors of the Bizantine  Church (Western Church) in the nabatean town of  Mamshit in the Negev Desert. This was a polichrome mosaic of about 80 square meters with geometrical, figurative decorations plus three inscriptions. The two months intervention on site was carried out by a team of 8 conservators and was implemented by using lime based techniques of in situ consolidation. A detailed documentation was carried out to record the consistency of the mosaic, the state of conservation, the treatments carried out.
When the intervention was almost completed the entire church was vandalized one night. The mosaic was heavily damaged and almost all figures and inscriptions destroyed. Local authorities immediately decided to answer with a strong political message and decided for a complete reconstruction of the mosaic. This was possible thanks to the accurate documentation carried out during the conservation intervention. The remaining mosaic was partially lifted, shipped to Rome, restored (or better re-made) and, after two years work, it was brougth back and relayed on site. This paper describes all those phases and concludes presenting the actual programme for future protection and maintenance on the monument.

La gestione e la manutenzione dei siti archeologici con mosaici


Nardi, R.

1998


Da molti anni a questa parte abbiamo assistito alla crescita  progressiva di una coscienza critica nei confronti del modo di gestire il patrimonio archeologico, quasi sempre cieco verso il suo penoso stato di conservazione. Si è così sviluppata una lenta maturazione che ha prodotto una attitudine costruttiva basata su una accresciuta capacità di lettura dei problemi. Primi risultati diretti di questa evoluzione sono gli interessanti seppur rari casi di riorganizzazione di siti archeologici che lentamente si realizzano e la disponibilità di informazioni tecniche che ci permettono di teorizzare proposte pronte per essere sperimentate sul campo. Nell’articolo si propongono alcune indicazioni metodologiche che possano essere tradotte in piani operativi sperimentali.

Conservazione e restauro. I mosaici


Nardi, R.

1998


In questo articolo si ripercorre il processo evolutivo che ha portato il concetto di "restauro del mosaico" verso la maturazione e l'attuale codificazione di un nuovo approccio chiamato "conservazione del mosaico", procedendo da un'analisi del significato che nella storia è stato attribuito alla decorazione musiva. Col mutare della percezione del valore delle opere dell'antichità, il restauratore é diventato conservatore: il manufatto non viene più "trasformato" e il messaggio dall'antico è mantenuto, evidenziato e trasmesso.

Per secoli, fino ad epoca recente, il restauro è stata una attività prevalentemente volta alla cura materiale del supporto lapideo destinata al ripristino della sola consistenza della materia.Attualmente, partendo dal presupposto tecnico del restauro , la conservazione dei materiali lapidei si pone come obiettivo, oltre al recupero e la cura della materia del supporto, lo studio, la lettura, l'interpretazione, la trasmissione e la valorizzazione dei dati storici registrati sulle superfici monumentali. In questo articolo si ripercorre il processo evolutivo che ha portato verso la maturazione e l'attuale codificazione  della disciplina della conservazione dei materiali lapidei.

The conservation of the mosaics in the thermae of the Cisiarii: technical report


Nardi, R. and Zizola, C.

1998


The project for the conservation of the mosaics of the thermae of the Cisiarii represents the practical application of one of the projects conceived in the framework of ICCROM's Forum project. The aim of this programme is to identify a safeguard policy which, once tested on a single archaeological monument, may then constitute a prototype applicable to the conservation of the entire site. The conservation project in question was developed by carrying out a direct intervention on the mosaic floors of the thermae of the Cisiarii and by applying preventive measures of safeguard. Concurrently, major emphasis was placed on offering information to the public in such a way so as to make it an active partner in the project. In this report we will describe all the phases of the project, its technical aspects and its methodological  principles. In conclusion, we will present the results of this experience.

Conservation: a direct route to the protection and study of monuments


Nardi, R.

1997


In this paper, we describe the experience of a private group of conservators working on public commissions in the sphere of monument and stone preservation. Three case studies of treatments performed from 1982-1992 are presented. In describing this experience, carried out in a very limited geographical area, we discuss the structure of the group, its strategy, (ethical and commercial), the commissioning agencies and the way work is assigned. We also examine the types of professionals who contributed to implementing the projects in respect of their technical-scientific training and their institutional positions.

The conservation of mosaics in situ


Nardi, R.

1997


The author stresses the importance of understanding the historical meaning of the different techniques employed in the past when treating archaeological mosaics in the present, during lifting, exhibiting or remounting, because these are directly related to how mosaics were or are historically appreciated by the public and the professionals that work directly with them. This is evidenced by the shift from the almost systematic lifting of mosaics to in situ conservation, application of principles of minimum intervention, reproducing antique formulations, and planning periodical maintenance. The function of the restorer is contrasted to his function in the past; from this point onwards he should conserve and preserve rather than transform mosaics, that is, the restorer should become the conservator. In this light, a list of new responsibilities demonstrates a new approach, where indirect actions prove to be more effective than direct treatments. Most importantly, the author provides his definition of in situ conservation, affirming that knowledge of the composition and deterioration mechanisms of mosaics is necessary for their direct treatment, when needed, which should be developed together with a maintenance plan. The discussion focused on this change of mentality and the visibility of its effects, as well as the definition of public.

Zippori, Israel. In situ conservation of a floor mosaic in polychrome stones and glass paste


Albini, R. and Zizola, C.

1996


During the 1991 excavation campaign of the University of South Florida, directed by Prof. J. Strange, in the National Park of Zippori in Israel, archeologists brought to light the main room of a public Roman building. The floor of the 100 square meter room is a polychrome mosaic dating from the III century A.D. As soon as it was excavated, the mosaic was protected by a temporary covering until the conservation intervention could begin. During the summer of 1995, the CCA, Centro di Conservazione Archeologica, carried out an in situ intervention using conservation techniques that respect both the materials and the technique of the original execution of the mosaic. Synthetic lifting materials were not used. This article will describe the methods and techniques that were used during the intervention. Special emphasis is given to those aspects that are peculiar to in situ conservation, in terms of planning and investment of human and economic resources.

Mamshit, Israel, and San Paolino alla Regola, Rome: what cooperation or interference between archaeologist and conservator can achieve


Albini, R., Costanzi Cobau, A. and Zizola, C.

1996


Archaeological sites are important for the messages that they convey from the past. Everything in archaeology must be devoted to the recovery, preservation, presentation and transmission of that message. Optimum results will be obtained when all professionals involved cooperate towards this common objective. This paper presents two cases of on-site conservation; frescoes of the 3rd century AD at Mamshit, Israel, and frescoes and mosaics of the 2nd century AD at San Paolino alla Regola, Rome. The first of these treatments was carried out many years after the excavation and represents an example of "maximum intervention-minimum efficiency". In the second case study, collaboration between conservator and archaeologist from the beginning of the excavation made it possible to follow the principle of "minimum intervention-maximum efficiency". Both the treatments presented used local materials similar to the originals. Preventive measures and maintenance programmes have been set up for future conservation.

Il progetto di conservazione dei mosaici delle terme dei Cisiarii rappresenta un'applicazione pratica di uno dei progetti concepiti nell'ambito dell'iniziativa dell'ICCROM (International Center for the Study of the Preservation and Restoration of Cultural Property) denominata Forum. Analoghi interventi sono stati realizzati in altri siti archeologici in Italia, Israele, Cipro. Obiettivo di queste iniziative è quello di individuare una politica di salvaguardia che, sperimentata su un solo monumento archeologico, potrà in seguito costituire un prototipo applicabile alla conservazione dell'intero sito. Il progetto di conservazione è stato sviluppato applicando un intervento preliminare diretto sui pavimenti e misure preventive di salvaguardia. Parallelamente è stato dato grande risalto all'informazione del pubblico in modo tale che divenisse parte attiva del programma. Descriveremo in questo articolo tutte le fasi del progetto, gli aspetti tecnici e i principi metodologici. In conclusione verranno presentati i risultati di questa sperimentazione.

Open-heart restoration: raising the awareness of the public


Nardi, R.

1995


In recent years, restoration projects have more and more often been open to the public. We may say that, in general, there has been an increase in the attention paid by the world of conservation to informing the media and the general public. In this paper we will examine this phenomenon in the light of the experience of the CCA, Centro di Conservazione Archeologica, which in the last ten years has opened its restoration worksites to the public whenever circumstances permitted. Underlying the enterprise of informing visitors is the consideration that every time the public is involved, the results are positive, in both the short and the long term:  in the short term, with a large participation in the initiative; in the long term, with an increased awareness on the subject of conservation. Thus if we believe that the protection of the cultural heritage must be obtained through systems of prevention, then the raising of public awareness is a key element: it will be the citizens themselves who, one day, will feel themselves to be participants in the responsibility and pleasure of protecting the cultural heritage.

Preventive conservation and restoration: a matter of costs


La Rocca E., Nardi R.

1994


In the treatment of seriously decayed monuments, the objective of the conservator is to return the monument to the point where ordinary maintenance is once again possible. One of the main difficulties is persuading administrations to approve programmes for the maintenance of newly restored monuments. Conservators have to change their language if they want to be understood. One of the strong points of maintenance is how much can be saved by developing a maintenance programme which avoids the need to repeat expensive restoration every 10 years. The authors present the maintenance programme planned for the structures of the Atrium of the Capitoline Museum and the collection of Roman sculptures on display, restored after two years of work.

Conservazione preventiva del mosaico nei siti archeologici


Nardi, R.

1994


Lo stato di conservazione del patrimonio musivo dei paesi mediterranei puo' essere descritto con aggettivi che vanno dal pessimo al catastrofico. In questo scritto si tenta un'analisi del problema e si traggono alcune conclusioni propositive.
La soluzione al problema potra' avvenire solo attraverso lo sviluppo di una cultura della programmazione e della protezione, ovvero attraverso la maturazione di una idea di prevenzione. E questo non puo' essere improvvisato; deve essere il frutto di un lungo processo educativo, da realizzare attraverso la formazione degli archeologi e degli amministratori del futuro.

Preventive conservation of mosaics at archaeological sites


Nardi, R.

1994


The state of preservation of mosaics in Mediterranean contries can be described with adjectives that range from "terrible" to "catastrophic". This article tries to analyze the problem and proposes some solutions. The problem can be solved only by developping a programme of planning and safekeeping, i.e. by affirming the concept of preventive conservation. Such an approach cannot be improvised: it can only develop as the result of a careful educational process that will effectively train future archaeologists and administrators.

The first step in preventive conservation: the analysis of the problem


Nardi, R.

1994


The first step in planning preventive conservation measures is to collect the information and to analyse the problems. This must be done in a systematic way, with a method capable to highlight the various components of the problem to help anybody involved in decisional tasks to operate in a proper way. Only when this operation is concluded it will be possible to plan a project capable to answer to the real needs of conservation of the monument. In this paper are presented two examples of analysis of problems concerning two different Roman mosaics, both in situ and not restored.

In situ consolidation of a Roman fresco near Ein Yael, Jerusalem


Costanzi Cobau, A.

1993


In the spring of 1990, the Department of Antiquities of Israel carried out an in situ conservation intervention of a Roman fresco from a villa near Ein Yael, located in the vicinity of Jerusalem. The intervention was carried out according to the following principles: in situ consolidation of the fresco; use of products compatible with the original components; application of techniques similar to the ancient ones; use of local products and equipment, roofing and protection against water as preventive measures; and a maintenance program. In the spring of 1992, an examination of the structure confirmed the highly effective intervention.

In situ consolidation of mosaics with techniques based on the use of lime


Costanzi Cobau, A. and Nardi, R.

1992


The concept of the mosaic as an isolated object is, we hope, now obsolete, given the value duly attributed to the inextricable relationship between the artifact and its context. This value is given material expression in maintaining the mosaic in situ, with all the technical consequences this choice brings with it. This article present an outline of in situ consolidation using lime-based techniques. The use of lime is not a simple technical operation but the result of centuries of practice, of knowledge handed down, of tradition.

Esempi di grafica assistita da computer a fini di documentazione


Nardi, R.

1992


The graphic documentation of the state of conservation of ancient monuments, and of the conservation processes applied to them, is considered today an essential feature of a serious conservation project. However, such documentation normally produces a vast amount of large-size drawings on paper which is costly to originate and to update; furthermore, it poses serious problems as to handling, storage and consultation. These problems may be solved by the use of computer graphics which allow a rapid update and reproduction of all drawings, once the basic survey data are memorized; furthermore the storage for archival purposes is much easier, considering the small volume that the data occupy in this form. The present paper illustrates some examples, and in particular the "Arch of Septimius Severus", in Rome. In the latter case the computer drawings on which various sets of data were recorded were printed on transparent sheets; this allows to examine drawings one by one or to superimpose a small number of them, in order to explore possible relationships between two or more sets of data.

Planning as a means of preventive conservation


Nardi, R.

1992


The article presents three case studies where planning is applied to three restoration projects. The human factor is considered as one of the main factors of deterioration of cultural heritage, especially when it entails lack of organization. On the opposite hand, a planning approach is one of the best, and with no doubt more effective, tool of preventive conservation. The planning methods presented in this article range from a simple flow-chart of the different project phases to the implementation of an informatic system in managing the project.

The Roman Forum. On-site conservation of floor surfaces during excavation


Costanzi Cobau, A.

1990


Over the last few decades the question of prevention in the field of archaeology has received widespread attention that the need for collaboration between conservator and archaeologist is taken for granted. There was a reciprocal, initial misunderstanding due mainly to various deficiencies in the training of conservators who found themselves working in (ideal) conditions far different from the ideal one they were used to in the laboratory. Here the causes of deterioration are discovered, isolated and removed. Instead, the conservator working with the archaeologist has learned to maneuver in a continually changing environment, where the causes of deterioration are directly linked to the most specific instrument of archaeology itself: the excavation. Archaeological conservation must step away from the concept of "first aid" emergency treatments and consider instead all the prevention and safeguarding operations that take into account the immediate surroundings, and generally have no evident verification.

Intonaci di età medievale


Costanzi Cobau, A.

1990


Negli strati di abbandono e distruzione dei periodi VIII-X, corrispondenti al XIV e alla prima metà del XV secolo, sono stati recuperati oltre 400 frammenti di intonaco dipinto che per le macroscopiche analogie riscontrate nello strato preparatorio, nella superficie pittorica, nella varietà di motivi e colori, costituiscono un insieme omogeneo, proveniente con ogni probabilità da un unico complesso decorativo, come tale qui analizzato.
Lo studio dei frammenti rinvenuti nella fossa cinquecentesca, qui rivisto nelle sue conclusioni, è stato un necessario punto di riferimento che, considerato alla luce dei nuovi ritrovamenti, su è rivelato di rande utilità sia per il confronto che per l’ampliamento delle tipologie già individuate. Il complesso risulta così costituito da oltre 1700 frammenti i quali, pur rappresentando certamente un lacerto dell’opera originale, coprono in totale quasi 5 metri quadrati.


Conservation of Archaeological Mosaics: the State of the Problem in the Light of a Recent International Course


Melucco, A., Nardi, R. and De Guichen, G.

1990


This article described the experience of the 1th International Course for the Safeguard of Archaeological Mosaics, held in Rome, 19 September - 13 October 1990. The course was organized by ICCROM and ICR (now ISCR). We feel that it could be of general interest, for it provided the means and the occasion to examine various points:

  • the state of conservation of archaeological mosaics in situ;
  • the reasons for a situation that appears extremely serious in our view, and possible conditions for improving it;
  • the relationship between specialized aspects, such as interventions on the mosaic per se, and management and conservation on the scale of the entire site;
  • professional training of directors and personnel responsible for the sites themselves;
  • the disparity of technical approach and theoretical foundation behind many proposed interventions.

Critical review of the specialized literature in mosaic conservation


Nardi, R.

1990


This article present a critical review of the specialized literature as the result of a study carried out during the preparation for the first International Course on the Safeguard of Archaeological Mosaics.  Basing ourselves on the presupposition that technical texts on conservation as well as in any other professional field, are a working and updating tool which different technicians can use regardless of regional distinctions, and that they are also the bases on which new generations of professionals will train, it was decided to analyze this "tool" more in depthThe method used in this research was to carry out an analysis of the texts by emphasizing certain characteristics such as the author, its context, the topics it treats, and the areas of application.  The first part devoted to more general themes such as date of publication, language of the text, professional qualifications of the author, general characteristics of the text, was followed by a more descriptive analysis of the actual mosaic such as the type, size, the geographical position, and the causes of deterioration.  The study ends with a detailed revision of the operations described and of the technical solutions adopted.

Il Tempio di Vespasiano: un palinsesto nella storia del Foro Romano


Nardi, R.

1988


Il Tempio di Vespasiano, per quanto riguarda la sua architettura e la sua valenza topografica, è troppo noto per doverne parlare in dettaglio. Del resto lo scopo del nostro lavoro non è questo; semmai esso riguarda le vicende che coinvolsero il monumento durante il periodo di abbandono.


Pompeya, Casa del bracciale. Intervencion conservativa en los mosaicos de la fuente


Cassio A., Nardi R.

1986


El mosaico, que tiene que ser considerado como un conjunto estratigràfico de teselado y soporte (sinopia donde exista) ya no es visto esclusivamente como una capa superficial de revestimiento, sino que asumió un valor históricotecnológico del cual hoy el conservador tiene que ser consciente. Esta consideración impone a la decisión metodológica de la praxis conservativa una dirección que lleve al intentar consolidar y mantener in situ la estructura completa en todas sus partes.
A pesar de esto, sobre todo cuando se opera en sitios con colocaciones y caracterlsticas disimiles nos podemos encontrar en la condición particular donde la decisión de separación del taselado sea la única posible solución.
El caso presentado pertenece a esta última categoria y es relativo a la intervención conservativa hecho sevre la fuente de la Casa del Bracciale, a Pompeya.

Excavated wall plasters: conservation problems


Costanzi Cobau, A.

1986


This report describes some conservation interventions on wall paintings and plasters discovered in situ at the Crypta Balbi excavation in Rome.

The following cases in particular are analyzed:

  • wall plasters on structures of tuff and travertine with problems of rising damp, water infiltration from the rear, and biological attack;
  • consolidation of mortars used as rendering on niches;
  • conservation assistance during excavation of frescoes on site;
  • sampling of plasters.

La conservazione sullo scavo archeologico


ICCROM-CCA

Traduzione in italiano, realizzata dal CCA Centro di Conservazione Archeologico di Roma, sul testo originale inglese Conservation on archaeological excavations: with particular reference to the Mediterranean area. Stanley-Price, N.P. (ed.), ICCROM, Rome, Italy (1984).
Conservazione sullo scavo archeologico significa prima di tutto prevenzione: intervento e monte su quei meccanismi che, secondo le leggi naturali della termodinamica, tendono a ricondurre a materie prime i prodotti materiali dell'attività umana. E la prevenzione può assumere due forme: una, diretta, basata sull'applicazione di interventi di tipo tecnico su ambiente e materia; una seconda, più lenta ma più profonda, fondata su processi culturali di formazione professionale di futuri tecnici responsabili. Una prevenzione preventiva.

Arco di Settimio Severo, analisi archeologica e conservativa 1979-83


Nardi R.

1986


Nel 1979 si è dato inizio ad una serie di studi sull’Arco di Settimio Severo, nati come argomento di tesi di laurea per la Cattedra di Rilievo e Analisi tecnica dei Monumenti Antichi, diretta dal prof. C.F. Giuliani; la ricerca è poi proseguita e oggi è possibile elencare una prima serie di risultati:

  • è concluso il rilievo grafico della metà sud del monumento;
  • è in via di pubblicazione una analisi critica delle fonti storiche e iconografiche;
  • è stata eseguita una mappatura dello stato di conservazione del progetto S-SE, nata come proposta sperimentale, e oggi estesa anche ad altri monumenti;
  • è stato redatto un progetto di intervento di restauro, che nel prossimo aprile diverrà operativo.

Conservation of the Arch of Septimus Severus: work in progress


Nardi, R.

1986


The Arch of Septimus Severus in the Roman Forum (built in 203 AD of marble over a travertine core) has been the object of many restorations in between periods of neglect. The innumerable traces on its surface provide important historical information; these layers had to be studied and graphically recorded before any intervention could be formally undertaken. The Centro di Conservazione Archeologica has carried out the necessary, detailed, computerized graphic survey to be regularly updated by the conservators. Operations of preconsolidation, cleaning and consolidation have taken place. Each phase is reported in detail and the techniques and materials used are listed, along with brand names and proportions. A very careful method of cleaning was to enclose the surfaces in wind-free chambers and nebulize water thus minimizing mechanical friction on the fragile surfaces. For the consolidation phase, care was taken to use crack fillers that would result in an homogeneous appearance. Integration was limited to the structural elements involved with the disposal of rainwater. The final protection phase is still a subject for research and testing.

Conservation on the excavation: the Crypt of Balbus in Roma


Nardi, R.

1986


The paper reports a series of in situ conservation interventions carried out during the excavation campaigns in the Crypta Balbi in Rome. The area, situated in the centre of the city, is more than 2500 sq.m. in area and is particularly interesting for its historical stratification of more than two millennia duration.
The interventions described are:

  • consolidation of a wall of mud brick laid in clay;
  • consolidation of a wall of fired bricks in clay;
  • consolidation of a floor mosaic;
  • recovery of ceramic material and a “Capuchin” tomb;
  • conservation/restoration of coins.

La pittura a calce: osservazioni


Costanzi Cobau A.

1985


Quando la calce, ovvero l’idrato di calce, viene unito al colore per eseguire una decorazione o una scialbatura su una superficie asciutta, la sua funzione di legante è simile a quella dell’affresco, dato che il pigmento è sempre fissato dalla carbonatazione della calce, ma si esplica in maniera differente. E’ noto infatti come nell’affresco i colori vengano applicati su un intonaco di calce e polvere di marmo (e/o altri materiali) mentre è ancora umido: la calce quindi esegue funzioni di supporto e contemporaneamente di legante. L’esecuzione di un’opera a fresco può comunque avere modalità e variazioni diverse rispetto la definizione canonica del “buon fresco” ed addirittura essere combinata con altre tecniche.
La pittura a calce può essere considerata una delle varianti della vera tecnica dell’affresco, anche se capovolge il suo presupposto principale: l’esecuzione su un intonaco ancora umido. Infatti la calce svolge, nella tecnica a secco, la funzione di legante e medium del pigmento, al quale viene unita prima di essere applicata sulla superficie secca da decorare, ma non quella di supporto.

Uno scarico di intonaci dipinti


Costanzi Cobau, A.

1985


Lo scavo di una fossa praticata a ridosso del muro circolare dell’esedra antica, verosimilmente in occasione dell’erezione del muro perimetrale del Conservatorio, ha consentito il recupero di un ingente scarico di frammenti di intonaci dipinti di età medioevale, che costituiscono un contesto omogeneo di considerevole interesse.
Si tratta di un complesso di 1335 frammenti, di cui il maggiore non supera i cm2 100 che denotano, dalla varietà delle campiture di sottofondo, di appartenere a più tipo di decorazione.
La probabilità di riuscita nella ricostruzione dei vari tipi è apparsa scarsa, vista la sproporzione tra la grandezza massima dei frammenti e la possibile superficie murale coperta, di cui non si conosce l’entità. Per questo è stato scelto il criterio della divisione per gruppi a seconda dei colori, delle sovrapposizioni degli stessi, del verso delle pennellate. Questo criterio ha permesso di distinguere le decorazioni sovradipinte dai motivi a bande colorate.


Due frammenti di pluteo alto medievale: nota sul restauro


Nardi R.

1985


La relazione tecnica di un restauro normalmente parte dalla descrizione dello stato di conservazione del pezzo, per poi passare alla descrizione, sempre scritta, delle operazioni effettuate; questo quando va bene. In un campo dove la sperimentazione continua prende il posto di regole precise (pur ammettendo metodologie generali), ma soprattutto dove niente è garantito “all’infinito”, l’assenza di informazioni chiare, esaustive e in special modo intellegibili e normalizzate è origine di danni gravi e specchio di una metodologia radicata negli anni, artefice del disastro che regna nel campo della conservazione dei beni culturali e soprattutto, visto che di cultura si è parlato, nella stessa formazione culturale degli addetti in materia (restauratori in prima fila, archeologi, amministrativi ecc.).

Notes en marge de la fréquentation du temple de Vespasien et Titus au Forum Romain


Nardi, R.

1985


Le temple de Vespasien et de Titus propose de nombreux éléments intéressants, lies a sa position topographique et a l’histoire de l’édifice et du site.
Il semble donc plus que jamais utile de reconnaitre de près les surfaces et d’effectuer une analyse comparée des résultats obtenus avec les sources historiques et iconographiques et les informations concernant les autres monuments de la zone.
C’est ce qui a été fait, en profitant de l’intervention de restauration en cours et des structures temporaires de couverture du monument.


Il restauro delle lapidi capitoline. Indagini preliminari


Nardi, R.

1984


La Galleria di Congiunzione è un ambiente ipogeo che ospita parte della Collezione Lapidaria Capitolina. Le epigrafi furono murate nelle pareti laterali delle sale sotterranee nel corso di una sistemazione generale degli ambienti negli anni 40-50.
Purtroppo, nonostante la meticolosità dell’intervento, che tenne conto del problema dell’isolamento igrometrico con l’erezione di doppi muri e dunque di un’intercapedine, ci troviamo di fronte a condizioni di cui per ora sfugge il controllo ma che hanno comunque determinato il danneggiamento grave delle lastre e reso impossibile il mantenimento in situ delle stesse.
Con questi presupposti e grazie all’interessamento e alla sensibilità della dott.ssa M. Mattei, responsabile del settore epigrafico dei Musei Capitolini, è stato dato avvio al programma di intervento, di cui il presente scritto è una breve presentazione, affidato al CCA, Centro di Conservazione Archeologica.


Project for the Arch of Septimius Severus, Rome


Nardi, R.

1984


The Arch of Septimius Severus is one of the Roman monuments included in the conservation programme under the auspices of the law for the archaeological-monumental heritage of Rome.
The intervention on the Arch of Septimius Severus began in 1979 and is being directed by the author and the Centro di Conservazione Archeologica (Centre for Archaeological Conservation), a private firm involved in the study, restoration and maintenance of ancient monuments, of which the author is the director. The current programme focuses on the study of the artefact, the planning and execution of the restoration intervention, and the planning and execution of the maintenance procedures. 


L'Arco di Settimio Severo: indagini storiche e conservative


Nardi, R.

1984


Gli studi sull’Arco di Settimio Severo nel Foro Romano sono iniziati nel 1979 nel corso di una tesi di laurea per la cattedra di Rilievo e Analisi tecnica dei Monumenti Antichi, diretta dal Professere C.F. Giuliani, dell’Università di Roma La Sapienza. Da allora si è passati da una fase preliminare di perfezionamento metodologico alla definizione di un piano d’intervento conservativo affidato al CCA nel 1984. Alla base della ricerca è stata posta l’osservazione diretta delle superfici originali, e il trasferimento su basi grafiche analitiche di tutti i segni e le informazioni raccolte, nella consapevolezza che un intervento conservativo rappresenta una straordinaria occasione di studio di un monumento, dagli aspetti storico - archeologici a quelli puramente conservativi.

Technique d'application de la fin du XVIIIe sicle et du debut du XIXe siecle de quelques pavements du Musee archologique de Naples


Cassio A., Nardi R.

1982


Les mosaiques detachées de Pompei et de la region au XVIIIe et XIXe siècles et servant actuellement de pavement au Musée de Naples ont du etre détachées pour permettre le renforcement des sols ebranlés lors du tremblement de terre de 1980. Ceci a permis d’étudier la technique d’application sur dalle de piperno. Il semble que les pavements y furent appliqués avec de la colophane alors que la dalle était maintenue chaude.

The mosaics from Pompei and the Campanian region that were detached in the 18th and 19th centuries and which now pave the floors of the Naples museum have had to be lifted once more to allow the consolidation of the underlying floors that were badly shacken during the 1980 earthquake. This has allowed the study of the technique used of applying mosaics on the piperno slabs. It seems that the pavement was laid using colophane was the slab was kept warm.


Couverture provisoire pour les mosaiques qu'on ne peut enlever


Nardi, R.

1982


Une expérience a été tentée pour trouver un matériel ou une combinaison de matériaux qui, mis au contact direct d’une mosaïque, permettrait une bonne protection temporaire er serait facilement enlevable et réutilisable. L’argile expansée donne de bons résultats mécaniques mais n’empêche pas les racines de pénétrer jusqu’au pavement a protéger.

An experiment was carried out in order to find a material or a combination of materials which, when placed in direct contact with a mosaic, offers a good temporary protection, is easily removable and can be re-used. Expanded clay gives good mechanical results but does not prevent roots from reaching the pavement to be protected.
