CARSIOLI, an ancient city of Italy (mod. CARSOLI), on the Via Valeria, 42m. E. by N. of Rome. It was founded in the country of the Aequi between 302 and 298 B.C., just after the establishment of Alba Fucens, no doubt as a stronghold to guard the road to the latter. It was sacked in the Social War. The old site does not seem to have been abandoned until the 13th cen tury.- It is now occupied only by vineyards, and lies about 2,f oof t. above sea-level, in a plain surrounded by mountains, now called Piano del Cavaliere. The line of the city walls can be traced, and so can the scanty remains of several buildings, including the base of a temple.
