A town in Gallia Transpadana near the head of the Adriatic, founded by the Romans in B.C.
182. It was a strong fortress, and intended to be a barrier against the encroachments of the
Northern barbarians. It was taken, however, in A.D. 452 by Attila
(q.v.), who destroyed it, the inhabitants escaping to the lagoons of the
Adriatic, where subsequently arose the city of Venice.
