Cyclops

In Greek and later Roman mythology, the Cyclopes are giant, one-eyed creatures; ancient sources distinguish separate kinds of Cyclopes. One group are the sons of Uranus and Gaia, gigantic smiths credited with forging Zeus's thunderbolts; another appears in Homer's Odyssey as a race of lawless, cave-dwelling shepherds, including Polyphemus, who traps and is later blinded by Odysseus; a third group is credited by later tradition with building the massive stone walls of Mycenaean cities, work still described today as Cyclopean masonry.
