ALTINUM (mod. Altino), Venetia, 12m. S.E. of Tarvisium (Treviso), on the lagoons. From a fishing village it became the junction of the Via Postumia and the Via Popilia (see AQv11,EIA). Augustus and his successors made it important as a point on the route between Italy and the north-east parts of the empire. After the foundation of the naval station at Ravenna, it became the practice to take ship from there to Altinum, and thence to con tinue the journey by land. A new road, the Via Claudia Augusta, was constructed by the emperor Claudius from Altinum to the Danube, a distance of 35om.
