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