Olympus  (o-lim ´pus ).—A mountain range on the boundary of Macedonia and Thessaly, of great height, and consequently regarded as the abode of the gods. Once the giants tried to reach heaven, and to do so piled Mount Pelion on Mount Ossa (both being high mountains in the neighborhood of Olympus); but Jupiter used his thunderbolts against them, and, with the assistance of Hercules, destroyed them all, and buried them under Mount Ætna.
