Ar'arat, MOUNT, a celebrated mountain of Armenia, in western Asia, on which, tradition says, Noah's ark rested. It rises in two volcanic cones, the higher one of which is 17,260 feet above sea level. Frightful earthquakes visit the region. In 1840, masses from the mountain were thrown into the plain, destroying the gardens, convent and chapel of the village of Arguri, and burying many people. Here Russian, Turkish and Persian territories meet, the summit of the mountain being Russian territory.
