The Cyclopes were triplet sons of Ouranos and Gaia. Like their elder brothers, the Hecatonchires, they are therefore close relatives of the Olympians. Named Arges, Brontes and Steropes, they were banished first by thier father, then by thier brother Kronus, before finally being freed by their nephew Zeus. They are master craftsmen and work closely with the Olympian Hephaestus.
