 The "Theogony" mentions a second ambiguous “she” as the mother of the Chimera (a fire-breathing beast that was part lion, part goat, and had a snake-headed tail) which may refer to Echidna, though possibly the Hydra or even Ceto was meant instead.Hesiod next names two more descendants of Echidna, the Sphinx, a monster with the head of a woman and the body of a winged lion, and the Nemean lion, killed by Heracles as his first labor.According to Hesiod, these two were the offspring of Echidna's son Orthrus and another ambiguous "she", read variously as the Chimera, Echidna herself, or even Ceto.
