A legend in the 12th-century "Chronicon Farfense" (Chronicle of Farfa) dates the founding of a monastery at Farfa to the time of the Emperors Julian, or Gratian, and attributes the founding to Laurence of Syria, who had come to Rome with his sister, Susannah, together with other monks, and had been made Bishop of Spoleto. According to the tradition, after being named bishop, he became enamoured of the monastic life, and chose a forested hill near the Farfa stream, a tributary of the Tiber, to build a church and a monastery. Archaeological discoveries in 1888 find strong evidence that the first monastic establishment was built on the ruins of a pagan temple. This first monastery was devastated by the Vandals in the fifth century. Only a handful of sixth-century finds document the early presence of the monastic community.
