The ancient Arcadians said that Apollo, incensed at Hercules’ having carried off the tripod from Delphi and brought it to Pheneos, inundated the valley, and that Hercules formed the chasms by which the waters ran off11. […] Three only of the poems ascribed to him have come down to us, viz. the didactic poem named Works and Days, the Theogony, and the Shield of Hercules. […] There were also Heracleiæ, or poems on the subject of Hercules, by Peisander, Panyasis, and other poets, a Theseïs on the adventures of Theseus, poems on the wars of Thebes82, a Titanomachia, an Amazonia, a Danaïs, a Phoronis, etc. […] Such was Prodicus’ beautiful fiction of the Choice of Hercules, and Protagoras’ story of Prometheus and his brother84. […] They are susceptible of injury by mortal weapons : the arrows of Hercules violate the divine bodies of Hera and Hades342; Diomedes wounds both Aphrodite and Ares343.
