Old and New Faiths, AD 1–450
As in any port city of the Roman world, the population of Ostia was very mixed. An extraordinary discovery was made on the outskirts of Ostia in 1961, while a road was being constructed linking Rome to its new door to the world, Fiumicino airport: the synagogue of Ostia, the oldest synagogue structure to have survived in Europe. The earliest part dates from the first century AD, but the building was repaired or partly rebuilt in the fourth century. It was in continuous use for Jewish prayer for at least 300 years. An inscription from the second century commemorates the building of the Ark for the scrolls of the Law, at the expense of a certain Mindis Faustos; the inscription is mainly in Greek, with a few Latin words, for the Jews of Rome, with their connections to the East, continued to use Greek as their daily language. The building and its annexes have an area of 856 square metres, and everything suggests that this was the major synagogue of a prosperous community of hundreds of Jews. More than a synagogue, by the fourth century the complex contained an oven, possibly for the baking of unleavened bread for Passover, and a ritual bath. There were side rooms that were probably used for teaching and for meetings of the Jewish council and of the rabbinical court. A carved architrave portrayed the great candlestick that had stood in the Temple, the ram’s horn blown at New Year, and the symbols of the Feast of Tabernacles, the citron and decorated palm branch. Nor was Judaism the only eastern cult with many followers in Ostia. A small brick-built temple elsewhere in the city has been identified as a shrine of Sarapis. Within the precinct there was a courtyard paved with a black-and-white mosaic of Nile scenes. Plenty of inscriptions refer to the cult of Isis; there were several shrines to Mithras, much favoured in the Roman army; during their wild ecstasies, male devotees of the mother-goddess Cybele, who was also worshipped at Ostia, were said to castrate themselves.
