This mountain [al-Judi] is one of those that divide Armenia on the south, from Mesopotamia, and that part of Assyria which is inhabited by the Kurds, from whom the mountains took the name Cardu, or Gardu, by the Greeks turned into Gordyae, and other names. ... Mount Al-Judi (which seems to be a corruption, though it be constantly so written by the Arabs, for Jordi, or Giordi) is also called Thamanin ..., probably from a town at the foot of it.
