AREBRIGIUM a town or village of the Salassi, mentioned only in the Itineraries, which place it on the road from Augusta Praetoria to the pass of the Graian Alps, 25 M. P. from the former city. (Itin. Ant. pp. 345, 347; Tab. Peut.) This distance coincides with the position of Prë St. Didier, a considerable village in an opening of the upper valley of Aosta, just where the great streams from the Southern flank of Mont Blancjoin the Dora, which descends from the Petit St. Bernard. As the first tolerably open space in the valley, it is supposed to have been the first halting-place of Hannibal after his passage of the Graian Alps. (Wickham and Cramer, Passage of Hannibal, p. 113, seq.) It is immediately at the foot of the Cramont, a mountain whose name is probably connected with CREMONIS JUGUM(Liv. 21.38.)
