VENOSA (anc. Venusia), a town of Naples, in the province of Basilicata, in a small plain, 23 miles N.N.E. of Potenza. It has a ruined castle of the fifteenth century, a splendid cathedral, several parish churches, five convents, an hospital, almshouses, an exchange, and a fine Norman abbey, with a church containing many interesting monuments. The ancient Venusia was a flourishing Roman colony; but it is chiefly remarkable as the birthplace of Horace, B.C. 63. Pop. 6000.
