Arno

Arno (classic Arnus), a river of Italy, which, rising in Monte Falterona, in the Apennines, flows first south, then north, then west, and, after a course of 180 miles, enters the Mediterranean by an artificial channel eight miles below Pisa. It has one tributary, the Elsa. The valley of the Arno is one of the most beautiful and fertile in Italy, but in winter the stream becomes a dangerous and swollen torrent. Florence occupies a charming position on both banks about 50 miles from the sea.
