The Zeus of Otricoli is an Ancient Roman bust found in Otricoli in 1175 that is now in the Sala Rotonda of the Pio-Clementine Vatican Museum.
It is presumed to be a Roman copy of a Hellenistic original. While some attributed the bust as a copy of the statue of Phidias at Olympia, numismatic reproductions of that famous statue would suggest otherwise. It appears to be more likely from subsequent centuries.
Otricoli is a town and comune in the province of Terni, Umbria, Italy. It is located on the Via Flaminia, near the east bank of the Tiber, 44 miles north of Rome and 12 miles south of Narni.
Anciently named Ocriculum, the Umbrian city concluded an alliance with Rome in 308 BC. The modern village lies on the site of the ancient town about two km north of the Roman relocation, which was moved down from the defensible position probably at the end of the Republican era, in order to be closer to the curve of the Tiber and the Via Flaminia, which crossed the river here to enter Umbria. Its river port was the "oil port", signalling the olive culture that supported its economy. A pensor lignarius ("weigher of wood") noted in a recently unearthed inscription, identifies a trade in timber and perhaps firewood (Soprintendenza per i Beni Culturali).
Excavations on the Roman site in 1775 and following years led to the discovery of the baths, a theatre, a basilica and other buildings. In the baths were found a number of works of art, now in the Vatican, notably the mosaic pavement of the Sala della Rotonda, Museo Pio-Clementino, and the celebrated head of Zeus (illustration, left) and the head of Claudius, both also shown in the Sala della Rotonda.
