The New International Encyclopædia/Milvian Bridge
MIL′VIAN BRIDGE. An ancient bridge over the Tiber at Rome, built in B.C. 109 by Marcus Æmilius Scaurus. At this bridge, in B.C. 63, Cicero caused the arrest of the ambassadors of the Allobrogi, who were conspiring with Catiline, and Maxentius was drowned there after his defeat by Constantine in A.D. 312. On the foundations of the ancient bridge stands the modern Ponte Molle.
