A bronze statue of Mars, the Roman god of war, was found in the ancient city of Zeugma in the course of an excavation campaign in 1999-2000. The statue represents one of the most interesting and spectacular finds from this city on the banks of the Euphrates river in southern Anatolia. Conservation treatment of the statue offered academics and technicians a chance to study ancient working and casting techniques; at the same time it posed a technical challenge to repair the metal's serious condition of deterioration. The treatment involved the use of endoscopic studies, baths to stabilize the material, and scientific investigations of the casting earth. A new steel support now permits a view of the statue in the round.
