The wooded mountain range of Parspatunik(Matiani mts.) was also known in Antiquity as Αρμενιωο Ορη - the Armenian Mountains, in which there was a passage Αρμενιων πυλών - Armenian Gate (Դրունք Հայոց), what was described in the III-rd century B.C. by a Greek author Eratosthenes(280-202 B.C.) and mentioned again by a XIV-th century Muslim historiographer Hamballah Ghazvini. The road passing through the Armenian Gate in the Middle Ages led to the famous Khudapery Bridge.
