AUGUSTA TRICASTINORUM
AUGUSTA TRICASTINORUM as Pliny (
3.4) calls it, or Augusta, as it is simply called in the Itineraries.
It was on the road between Valentia (
Valence), on the Rhone, and Dea Vocontiorum (
Die).
It is said to be
Aoust-en-Diois, on the Drôme a branch of the Rhone, and in the department of
Drôme. D'Anville places Augusta Tricastinorum at
St. Paultrois-Châteaux, north of
Orange; and the Augusta of the Itineraries at
Aouste. There are said to be considerable remains at
Aouste. [
