（τὰ Ῥιπαῖα ὄρη
). The name of a lofty range of
mountains in the northern part of the earth, respecting which there are diverse statements in
the ancient writers. The name seems to have been given by the Greek poets quite indefinitely

sometimes called the Hyperborei Montes. (See Hyperborei

northeast of Mount Alaunus on the frontiers of Asiatic Sarmatia, and state that the
Tanaïs rises in these mountains. According to this account the Rhipaean Mountains may
be regarded as a western branch of the Ural Mountains (Mela, i.
