Lucus Augusti
Eth. Lucus Augusti a town in Gallia Narbonensis, and east of the Rhone, which Tacitus (Tac. Hist. 1.66) calls municipium Vocontiorum;
and Pliny (3.4) names Vasio (Vaison) and Lucus Augusti the two chief towns of the Vocontii. Lucus is placed in the Itins. on a road from Vapincum (Gap) to Lugdunum (Lyon): it is the first stage after Mons Seleucus, and lies between Mons Seleucus and Dea Vocontiorum (Die). The name is preserved in Luc. This town has been destroyed by the fall of a rock, which, having stopped the course of the Drôme, has caused the river to spread out and form lakes which have covered part of its territory: there remains, however, in the neighbourhood and at the outlet of these lakes a place which preserves the name of Luc.
(D'Anville, Notice, &c.) It is stated in the Guide du Voyageur (Richard et Hocquart), that on the mountain called the Pied de Luc, in the commune of Luc-en-Diois, there are considerable remains of old buildings. The column of the public fountain of this little place is a fragment of an old capital, and the basin is a sarcophagus of a single stone.
There is an inscription on it in Roman characters.
