 In any case, the lyric poet Lasus of Hermione (6th century BC), has Echidna and Typhon as the parents of the Sphinx, while the playwright Euripides (5th century BC), has Echidna as her mother, without mentioning a father.While mentioning Cerberus and "other monsters" as being the offspring of Echidna and Typhon, the mythographer Acusilaus (6th century BC) adds the Caucasian Eagle that ate the liver of Prometheus.Pherecydes also names Prometheus' eagle, and adds Ladon (though Pherecydes does not use this name), the dragon that guarded the golden apples in the Garden of the Hesperides (according to Hesiod, the offspring of Ceto and Phorcys).
