The ancients considered Exilles the first place in Italy coming from Gaul over the Alpine passes. As Scingomagus (Ancient Greek: Σκιγγόμαγος), Exilles is first mentioned by Strabo,[6] who, when speaking of one of the passes of the Alps, says that from Ebrodunum (modern Embrun) on the Gallic side through Brigantium (modern Briançon) and Scingomagus and the pass of the Alps to Ocelum, the limit of the land of Cottius (the Alpes Cottiae) is 159 kilometres (99 mi); and at Scingomagus Italy begins, the distance from Scincomagus to Ocelum being 43 kilometres (27 mi). Pliny the Elder also makes Italy extend to the Alps at Scingomagus, and then he gives the breadth of Gallia from Scingomagus to the Pyrenees and Illiberis.
