anciently called Eridanus, especially by the Greeks; a river famous for the fable of Phaeton, (Ovid). It rises in mount Vesuvius, in the Alpes Cottiae, from three springs, dividing the Cisalpine Gaul into the Transpadana and Cispadana, (Strabo); and, swelled by other rivers falling into it on each side from the Alps and Appennines, it discharges itself with a course from west to east, at seven mouths, into the Adriatic, (Mela). The lake thro' which it discharges itself into the sea, is called by the natives the Seven Seas. Now the Po.
