A name given to three distinct classes of mythological beings: a set of one-eyed savage giants infesting the coasts of Sicily and preying upon human flesh; a set of Titans, also one-eyed, belonging to the race of the gods, three in number, viz., Brontes, Steropes, and Arges—three great elemental powers of nature, subjected by and subject to Zeus; and a people of Thrace, famed for their skill in building.
