Apennīnus

A great chain of mountains in Italy, branching off from the Maritime Alps, in the neighbourhood of Genoa, running diagonally from the Ligurian Gulf to the Adriatic, in the vicinity of Ancona; from thence continuing nearly parallel with the latter gulf, as far as the promontory of Garganus, and again inclining to the Maré Inferum, until it finally terminates in the promontory of Leucopetra near Rhegium. The length is about 700 miles (Polyb. ii. 16).
