Librum Hypernaturalae 033 Picture

Echidna of Arima, wife of Typhon. She is among the most infamous of the Phorcydes, the children of Phorcys and Ceto.
Her epithet, "Mother of Monsters," is quite well-earned, as her children by Typhon, and according to Hesiod, by her son, the two-headed hound, Orthrus, were among the most famous monsters of Greek Mythology.

Besides Orthrus, a few of Echidna's better known spawn included the Hydra, Cerberus, the Chimera, the Nemean Lion, and the Teumessian Vixen.
