or LEONTIUM, (anc. geogr.) a town of Sicily on the south side of the river Terias, 20 miles north-west of Syracuse. The territory, called Campi Leontini, was extremely fertile, (Cicero): there were the Campi Leptigronis, anciently so-called; the seat of the Leptigrons, according to the commentators on the poets. The name Leontini is from Leo, the impression on their coin being a lion. Now called Lentini, a town situated in the Val di Noto, in the south-east of Sicily.
