A range of mountains separating Thrace and Msia, called by the classic writers Cold Hmos. (Greek, cheimon, winter; Latin, hiems; Sanskrit, hima.)
O'er high Pieria thence her course she bore, O'er fair Emathia's ever-pleasing shore; O'er Hæmus' hills with snows eternal crown'd, Nor once her flying foot approached the ground.
Pope: Homer's Iliad, xiv.
