LABICI, an ancient city of Latium, the modern Monte Compatri, about 17 m. S.E. from Rome, on the northern slopes of the Alban Hills, 1739 ft. above sea-level. It occurs among the thirty cities of the Latin League, and it is said to have joined the Aequi in 419 B.C. and to have been captured by the Romans in 418. After this it does not appear in history, and in the time of Cicero and Strabo was almost entirely deserted if not destroyed. Traces of its ancient walls have been noticed. Its place was taken by the respublica Lavicanorum Quintanensium, the post-station established in the lower ground on the Via Labicana (see Labicana, Via), a little S.W. of the modern village of Colonna, the site of which is attested by various inscriptions and by the course of the road itself.
