Gigantomachy
The war in which the Giants challenge the gods; the Library makes Heracles part of the victory condition.

Overview
The Gigantomachy is a later challenge to Olympian order rather than a simple repetition of the Titan War. Hesiod links the Giants’ origin to the blood that falls on Gaia after Uranus is wounded, while Pseudo-Apollodorus narrates a later war in which the Giants attack the gods. In that version, the gods cannot complete the victory without the mortal hero Heracles. The event therefore binds three layers together: old violence from the succession myth, the threatened authority of Olympus, and the heroic age entering a cosmic conflict.
