FLAVI´NIUM or FLAVINA, a small town of Etruria, known only from Virgil, who speaks of the Flavinia arva,a nd Silius Italicus, who calls the name of the town Flavina,--though Servius tells us it was Flavinium. We may probably infer, from the names with which it is associated by Virgil, that it was somewhere in the neighbourhood of the Faliscans and Soracte; and it has been placed, with some plausibility, at Fiano, between the foot of Soracte and the Tiber, about 25 miles from Rome, (Verg. A. 7.696, and Serv. ad loc.;Sil. Ital.; Gell, Top. of Rome, p. 244.)
