Narrative
Hesiod pairs Phorcys and fair-cheeked Ceto, children of Pontus and Gaia, as parents of the terrors at the world’s rim. First they bear the Graeae—Pemphredo of fine robes and saffron-garbed Enyo (handbooks add Deino)—gray-haired from birth, whom gods and men call the Old Women; they share one eye and one tooth among them and dwell where night meets the west. Next the Gorgons: Stheno, Euryale, and Medusa, who lives by the Hesperides beyond Ocean; Stheno and Euryale are immortal, Medusa mortal. When Perseus later takes Medusa’s head, Chrysaor and the horse Pegasus spring from her neck—Poseidon’s children by her—so the Phorcid line feeds both monster-slaying and wonder-birth.
In the same genealogical stretch Hesiod nests further Phorcid or Ceto-linked beings: the serpent Ladon coiled about the golden apples, and Echidna in her cave, from whom (with Typhon) spring Orthrus, Cerberus, Hydra, and Chimera. This file isolates the Phorcys–Ceto marriage and the Graeae/Gorgon core as the sea-monster genealogy proper—distinct from Pontus’s full first generation and from Echidna’s labor-brood list—so Perseus’s helpers and victims have a clear theogonic parentage.
