The Romans had two important roads built from Clavenna: the itineraries demonstrate that the route up the Valle Spluga to Splügen Pass was frequented in ancient times; as well as another, which separated from it at Clavenna, and led by a more circuitous route up the Val Bregaglia (Val Chiavenna) and across Septimer Pass to Curia (modern Chur), where it rejoined the preceding road. (Itin. Ant. pp. 277, 278; Tab. Peut.; P. Diac. vi. 29.) These passes had already played an important role as a line of supply for the Roman legion. It was by one or other of the roads that Magister militium Stilicho crossed the Alps in midwinter, a feat celebrated by Claudian (de B. Get. 320-358).
