One of the three Graeae, Pephredo's name meant 'dread'. Daughters of Phorkys and Keto, the Graeae were, like the Gorgons, three in number, and their names were Deino, Pephredo and Enyo, the last of whom was the goddess of war. The names of the three meant respectively 'alarm', 'dread' and 'horror'. As sisters to the Gorgons, the Graeae were also guardians of the trio, and were represented as misshapen and hideous creatures, hoary and withered from birth, with only one eye and one tooth between them. They lived in a dark cavern, near the entrance to Tartaros.
