SIRIO in Gallia, is placed by the Itins. on a road from Burdigala ( Bordeaux) to Aginnum (Agen). The distance is probably corrupt in the Table, which places Sirio x. from Bordeaux;for the true distance is xv. or xvi. Gallic leagues. D'Anville fixes Sirio (the Pont de Siron) near the point where the small river Sironor Cironjoins the Garonneon the left bank.
