Ocra Mons
ἡ Ὄκρα
Ocra Mons (ἡ Ὄκρα), is the name given by Strabo to the lowest part of the Julian or Carnic Alps, over which was the pass leading from Aquileia to Aemona (Laybach), and from thence into Pannonia and the countries on the Danube. (Strab. iv. p.207, vii. p. 314.) The mountain meant is evidently that between Adelsberg and Laybach, which must in all ages have been the principal line of communication from the Danube and the valley of the Save with Italy.
