Cyclops

            The Cyclopes were almost like human beings but of a gigantic size and with only one eye in the middle of their heads. Essentially there were three of them: Brontes,  Steropes, and Arges.

The Cyclopes were said to be the first smiths and volcanos were believed to be the aftermath of their underground work. When Cronus came to power he had imprisoned the Cyclopes. They were released by Zeus and fought with him against the Titans. As a reward for their release the Cyclopes gave Zeus his weapons of lighting and thunder. They continued as his workers at Mount Olympus, forging his thunderbolts.
