The Cyclops (Ancient Greek: Κύκλωψ (Kúklōps), meaning "Round-Eyed" or "Wheel-Eyed"), is a member of a primordial race of humanoid giants with a single eye in the middle of its forehead. In English, the plural cyclopses are also used.
They are characters of Greek mythology. The first group of Cyclopes is Brontes, Steropes, and Arges. Their children are Euryalos, Elatreus, Trachios, and Halimedes. The Elder Cyclopes were the children of Gaia and Ouranós where they later made Zeus' Master Thunderbolt, Poseidon's Trident, and Hades' Helm of Darkness during the Titanomachy. The younger Cyclopes are the sons of Poseidon, who are featured in the Odyssey.
Cyclopes (whose name means 'circle-eyed' or "round eye") are one-eyed giants who first appeared in Greek mythology. They were the children of the Earth (Gaia) and the Sky (Gaia's son Ouranos/Uranus) and are brothers to the Hecatoncheires (Hundred-Handed Ones). The three original cyclops were named Brontes (Thunder), Steropes (Lightning), and Arges (Bright). Their father, Uranus, feared their strength and threw them into the pit of Tartarus with their brothers, the Hundred-Handed Ones, where they were imprisoned. They were later let out by Zeus and forged the thunderbolt for him. Some authors also said that they were the workmen of Hephaestus, and that Apollo slayed them for creating Zeus's thunderbolt, which Zeus used to kill Apollo's son, Asclepius
Later in mythology, cyclopes were depicted as savage and not as civilized as the Greeks. The Greeks believed they lived in a faraway land without law and order. One famous cyclops is Polyphemus, who attacked and was blinded by Odysseus and his men.
