Falerii (also called Aequum Faliscum or Fa-lisca), an ancient city of Italy, one of the 12 Etruscan cities, a few miles W. of the Tiber, and X. W. of Mount Soracte, near Civita Castellana. It was the capital and perhaps the only city of the Falisci, a people of Pelasgic origin, whose territory extended from the Tiber to Lake Vico, and who in the early ages of Rome were reckoned among the most dangerous enemies of the republic. It is first mentioned in 437 B. C, when the Falisci lent their support to the Fi-denates, who had revolted against Rome. It was besieged and taken by Camillus about 394. The inhabitants again joined the enemies of Rome in 356; made a treaty in 352; revolted anew about 312, and were subjugated; rose in rebellion again in 293, and again in 241, when they were punished by the destruction of their town. They were removed to a less defensible site, where a colony was established named Junonia Faliscorum, from a famous temple of Juno. The latter site is now occupied only by a farm house and a ruined church, known as Sta. Maria di Falari, but a large portion of the ancient walls, with their gates and towers, still exists.
