LAUS, or LAOS (anc. geog.), a river of Italy, separating Lucania from the Bruttii, and running from east to west into the Tuscan sea; with a cognominal bay, and a town, the last of Lucania, a little above the sea; a colony from Sybaris, according to Strabo, Pliny, Stephanus. Both town and river are now called Laino, in the Calabria Citra; and the bay, called Golfo della Scalca, or di Polucastro, two adjoining towns, is a part of the Tuscan sea, extending between the promontory Palinurus and the mouth of the Laus.
