What the source books say

King Iobates orders Bellerophon to kill the Chimera because he expects the mission to destroy the hero. Apollodorus says that even a crowd of men could not easily subdue the creature. It has the power of three beasts, breathes fire, and lays waste to the surrounding country and cattle.[1]

Bellerophon mounts the winged horse Pegasus, flies above the monster, and brings it down with his bow. Hesiod supplies an earlier compact description: the Chimera is immense, swift, strong, three-headed, and fire-breathing, and Pegasus and Bellerophon kill it together.[2]

Source boundary: The selected texts describe a single body composed of three beasts, but they do not prescribe every detail familiar from later art. Colour, size, horns, and the exact way the goat and dragon parts join the lion vary by artist and adaptation.

Description and abilities

Apollodorus places the lion at the front, the dragon at the rear, and a goat’s head in the middle; fire comes from the goat head. Hesiod instead speaks of three heads—lion, goat, and dragon—and stresses the creature’s speed and strength. Both accounts make its composite form and fire breath essential.[1] [2]

  • Combines three different animals in one body
  • Breathes a destructive blast of fire
  • Ravages countryside and livestock
  • Is too dangerous for ordinary numbers to overcome easily
  • Is defeated by an airborne rider and winged horse

Source realm: Lycia

The encounter belongs to Bellerophon’s trials in Lycia, where Iobates rules. The Chimera threatens both cultivated land and herds, while Pegasus changes the battlefield by carrying Bellerophon above the creature’s reach. The episode connects a regional monster to the wider divine geography of Pegasus and the Gorgons.

Role in the myth

An impossible commission

Iobates chooses the Chimera because its reputation makes the task look fatal. The monster is part of a human plot to destroy Bellerophon without openly executing him.

Three dangers in one

The combination of predator, horned animal, serpent-like dragon, and fire makes the Chimera more than an unusually large beast. Its body is itself a catalogue of threats.

Flight changes the contest

Bellerophon succeeds through Pegasus as well as personal skill. The sources pair hero and horse against a creature ordinary fighters cannot readily master.
