Divine Bronze of Hephaestus

Mythological · Legendary · Ancient

The metal worked by Hephaestus in his divine forge on Olympus. Described in Homer and Hesiod as categorically different from mortal bronze: impervious to mundane damage, capable of wounding divine flesh, and able to conduct divine power without degradation. The automatons of Hephaestus were wrought from it.
