SUASA(σουάσα: Eth. Suasanus: Ru. near Castel Leone), a town of Umbria mentioned both by Ptolemy and Pliny, of whom the latter reckons it among the municipal towns of that country. Ptolemy places it, together with Ostra, in the district of the Senones, and it was therefore situated on the northern declivity of the Apennines. Its site is clearly identified at a spot between S. Lorenzoand Castel Leonein the valley of the Cesano, about 18 miles from the sea. Considerable ruins were still extant on the spot in the time of Cluver, including the remains of the walls, gates, a theatre, &c. and inscriptions found there left no doubt of their identification. (Cluver, Ital. p. 620.)
