(Cæsar, Strabo); Araris, (Dio Cassius); Saone, (Amian): A river of Celtic Gaul, now the Saone; which rises out of Mount Vogelus on the confines of Lorraine, runs through the Franche Comté and Burgundy, and below Lyons falls into the Rhone. It is so incredibly slow, that the eye cannot distinguish which way it moves, (Cæsar); and therefore Pliny calls it the sluggish river. Its course is from north to south. It is famous for a bridge of Cæsar, which was built by the soldiers in one day. It is navigable equally with the Rhone.
