LAUS, or LAOS, in Ancient Geography, a river of Italy, separating Lucania from the Brutii, 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, Piny, and Stephanus. Both town and river are now called Laino, in the Calabria Citra; and the bay called Golfo della Scala, or di Policestro, two adjoining towns, is a part of the Tuscan sea, extending between the promontory Palinurus and the mouth of the Laus.
