Apta Julia
Apta Julia (Apt), a city of the Vulgientes, on the road from Arelate (Arles), on the Rhone, along the valley of the Durance, to Augusta Taurinorum (Turino). The name Julia implies that it was a colonia, which is proved by inscriptions, though Pliny (3.4; and the note in Harduin‘s edition) calls it a Latin town, that is, a town which had the Jus Latium. The modern town of Apt, on the Calavon or Caulon, a branch of the Durance, contains some ancient remains.
