Cyclopes
Three one-eyed brothers whose release by Zeus is answered with the gift of thunder.

Overview
The Cyclopes are represented collectively here as the three brothers Brontes, Steropes and Arges. Hesiod makes them children of Gaia and Uranus, shaped like gods but with one eye in the forehead; their names evoke thunder, lightning and brightness. Uranus hides them, and Zeus later frees them from bondage. The poem calls the release a kindness but does not say Zeus acts to obtain weapons. Remembering the favour, they give thunder, lightning and the thunderbolt, establishing power for the next book’s Titanomachy without narrating that war here. The Titanomachy carries the thunder gift into battle; Pseudo-Apollodorus separately adds Poseidon's trident and Hades's helmet, so the three weapons need to be read by source.
