They had a thunderbolt, which their hands had shaped, like the many that the Father hurls down from all over heaven upon earth, in part already polished, while part remained unfinished. Three shafts of twisted hail they had added to it, three of watery cloud, three of ruddy flame and the winged South Wind; now they were blending into the work terrifying flashes, noise, and fear, and wrath with pursuing flames. Elsewhere they were hurrying on for Mars a chariot and flying wheels, with which he stirs upmen and cities; and eagerly with golden scales of serpents were burnishing the awful aegis, armour of wrathful Pallas, the interwoven snakes, and on the breast of the goddess the Gorgon herself, with neck severed and eyes revolving. Apollodorus
The mythographer Apollodorus, gives an account of the Hesiodic Cyclopes similar to that of Hesiods, but with some differences, and additional details. According to Apollodorus, the Cyclopes were born after the Hundred-Handers, but before the Titans (unlike Hesiod who makes the Titans the eldest and the Hundred-Handers the youngest).Uranus bound the Hundred-Handers and the Cyclopes, and cast them all into Tartarus, "a gloomy place in Hades as far distant from earth as earth is distant from the sky." But the Titans are, apparently, allowed to remain free (unlike in Hesiod). When the Titans overthrew Uranus, they freed the Hundred-Handers and Cyclopes (unlike in Hesiod, where they apparently remained imprisoned), and made Cronus their sovereign.
In Greek mythology and later Roman mythology, the Cyclopes ( sy-KLOH-peez; Greek: Κύκλωπες, Kýklōpes, "Circle-eyes" or "Round-eyes"; singular Cyclops  SY-klops; Κύκλωψ, Kýklōps) are giant one-eyed creatures. Three groups of Cyclopes can be distinguished. In Hesiods Theogony, the Cyclopes are the three brothers Brontes, Steropes, and Arges, who made for Zeus his weapon the thunderbolt. In Homers Odyssey, they are an uncivilized group of shepherds, the brethren of Polyphemus encountered by Odysseus. Cyclopes were also famous as the builders of the Cyclopean walls of Mycenae and Tiryns. In Cyclops, the fifth-century BC play by Euripides, a chorus of satyrs offers comic relief based on the encounter of Odysseus and Polyphemus. The third-century BC poet Callimachus makes the Hesiodic Cyclopes the assistants of smith-god Hephaestus; as does Virgil in the Latin epic Aeneid, where he seems to equate the Hesiodic and Homeric Cyclopes. From at least the fifth century BC, Cyclopes have been associated with the island of Sicily and the volcanic Aeolian Islands. Kinds
Three groups of Cyclopes can be distinguished: the Hesiodic, the Homeric and the wall-builders. In Hesiods Theogony, the Cyclopes are the three brothers: Brontes, Steropes, and Arges, sons of Uranus and Gaia, who made for Zeus his characteristic weapon, the thunderbolt. In Homers Odyssey, the Cyclopes are an uncivilized group of shepherds, one of whom, Polyphemus, the son of Poseidon, is encountered by Odysseus. Cyclopes were also said to have been the builders of the Cyclopean walls of Mycenae and Tiryns.
