Top Questions

  • Were all the Greek creatures enemies of the gods and heroes?

    Many of the Greek myths describe battles between a fearsome creature and a god or hero—between Typhoeus and Zeus, for example, or Medusa and Perseus, or the Chimera and Bellerophon. But some creatures, including the Centaur Chiron or even some of the Cyclopes, were friends and benefactors of gods and mortals.

  • Were any Greek mythical creatures immortal?

    Though many creatures could be killed, others were immortal, including Cerberus (the guard dog of the Underworld), the Hecatoncheires, the elder Cyclopes, and the centaur Chiron.

  • Were creatures ever worshiped in ancient Greece?

    The ancient Greeks generally did not worship creatures or monsters from myth, though some of them were associated with the chthonic gods who presided over death and the subterranean world.


Greek mythology is full of fantastic and terrifying creatures, many of whom were born at the dawn of creation. The one-eyed Cyclopes and the Hecatoncheires (“Hundred-Handers”), for example, were offspring of Gaia, the primordial earth deity. But there were countless other creatures in Greek mythology, diverse in appearance and abilities.

These creatures were often enemies of the gods and heroes. They represented a class of “chthonic” gods associated with death, darkness, and the earth—the antithesis of the Olympians, who stood for life, light, and the heavens.

Because of this, many of these creatures were killed by either the Olympians themselves or by the heroic mortals they championed. Typhoeus, for example, was killed by Zeus; Python by Apollo; Medusa by Perseus. Heracles was especially notable among the Greek heroes for his monster-slaying prowess, which cleared the path for the beginnings of civilization.
