Locri, Or Locri Epizephyrii, ( " Western Lo-cri"), an ancient city of southern Italy, situated on the S. E. coast of the Bruttian peninsula. It was founded by a colony from Locris, Greece, in the 7th century B. C, and became celebrated by the laws of Zaleucus. In later times Locri was generally an ally of Syracuse, whose tyrant, the elder Dionysius, married a Locrian woman. When Pyrrhus of Epirus invaded Italy in 280, Locri was garrisoned by a Roman force. On his approach the Locri-ans drove out the Romans, and declared for the Epirote, but subsequently rose against the mercenaries whom he had stationed in their citadel during his absence in Sicily. Pyrrhus on his return levied heavy contributions upon them, and carried off a great part of the treasure deposited in the temple of Proserpine. After the departure of Pyrrhus from Italy Locri again submitted to Rome, but in 216, on receiving intelligence of Hannibal's great victory at Cannae, went over to the Carthaginians. In 205 the treachery of the aristocracy enabled the Romans to recover possession of the city.

From this period we hear little of Locri. It existed however as late as the 6th century A. D., and was probably destroyed by the Saracens. Modern travellers have discovered its ruins near the Neapolitan town of Gerace, where are the fragments of a Doric temple, supposed to have been that of Proserpine.
