Echidna (E-kidʹ-na)
.Half-woman, half-serpent. She was mother of the Chimæra, the many-headed dog Orthos, the hundred - headed dragon of the Hesperides, the Colʹchian dragon, the Sphinx, Cerʹberos, Scylla, the Gorgons, the Lernæan hydra, the vulture that gnawed away the liver of Promeʹtheus, and the Nemʹean lion. (Hesiod.)
“[She] seemed a woman to the waist, and fair
But ended foul in many a scaly fold,
Voluminous and vast.”
