On the 23rd of May 2014, Prof. Roberto Nardi will give a lecture at the Institut National du Patrimoine (INP), Tunisia.
The event will take place at 10.00am in Driba Hall, in the headquarters of INP.
The topic of the lecture will be "The conservation of the mosaic of the Transfiguration in the monastery of Saint Catherine in Sinai". He will present the conservation project carried out by Centro di Conservazione Archeologica (CCA), Rome, from 2005 to today.
The mosaic of the Transfiguration covers a surface of 46 m2 in the basilica of the Monastery of St. 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 Bizantine art. Over the centurie, it has suffered extensive damage due to earthquakes and intense visitation by pilgrims from all conrners 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 tasselatum. 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, Centro di Conservazione Archeologica, was asked to do the restoration.The work began in 2005.
