a creature fearful,
 great, swift footed and strong, who had three heads, one of a
 grim-eyed lion, another of a goat, and another of a snake, a fierce
 dragon; in her forepart she was a lion; in her hinderpart, a dragon;
 and in her middle, a goat, breathing forth a fearful blast of blazing
 fire. Her did Pegasus and
 noble Bellerophon slay; but Echidna was subject in love to Orthus and
 brought forth the deadly Sphinx which destroyed the Cadmeans, and the
 Nemean lion, which Hera, the good wife of Zeus, brought up and made to
 haunt the hills of Nemea , a
 plague to men. There he preyed
 upon the tribes of her own people and had power over Tretus of
 Nemea and Apesas: yet
 the strength of stout Heracles overcame him. And Ceto was joined in
 love to Phorcys and bore her youngest, the awful snake who
 guards the apples all of
 gold in the secret places of the dark earth at its great bounds. This
 is the offspring of Ceto and Phorcys.
