Two other poems are ascribed to Hesiod. Of these the “Aegimius” (also ascribed by Athenaeus to Cercops of Miletus), is thought by Valckenaer to deal with the war of Aegimus against the Lapithae and the aid furnished to him by Heracles, and with the history of Aegimius and his sons. Otto Muller suggests that the introduction of Thetis and of Phrixus (frags. 1-2) is to be connected with notices of the allies of the Lapithae from Phthiotis and Iolchus, and that the story of Io was incidental to a narrative of Heracles’ expedition against Euboea. The remaining poem, the “Melampodia”, was a work in three books, whose plan it is impossible to recover. Its subject, however, seems to have been the histories of famous seers like Mopsus, Calchas, and Teiresias, and it probably took its name from Melampus, the most famous of them all.
