The official in charge was a Roman, and, struck by the size of the victim which was well known by report he recalled the prophecy and addressing the Sabine said, “Why, pray, are you, stranger, preparing to offer a polluted sacrifice to Diana? Go and bathe yourself first in running water. The Tiber is flowing down there at the bottom of the valley.”
