Heracles Driven Mad

Now it came to pass that after the battle with the Minyans Hercules was driven mad through the jealousy of Hera and flung his own children, whom he had by Megara, and two children of Iphicles into the fire; wherefore he condemned himself to exile, and was purified by Thespius, and repairing to Delphi he inquired of the god where he should dwell. The Pythian priestess then first called him Hercules, for hitherto he was called Alcides. And she told him to dwell in Tiryns, serving Eurystheus for twelve years and to perform the ten labours imposed on him, and so, she said, when the tasks were accomplished, he would be immortal.
