INTRODUCTION TO THE HERACLEIDAE The Legend Eurystheus, king of Argos, was given control over his cousin Heracles through the contrivance of Hera. He persecuted Heracles throughout that hero's life, sending him on the famous and perilous "Labors." After Heracles had died and been transformed into a god, Eurystheus continued to perse- cute the family. Wherever these disinherited refugees went, he would send his herald to demand that they be denied sanc- tuary. He was the most powerful king in Greece, and none dared resist him. But in Attica the Heracleidae finally found a state which was willing to defend their rights; and when Eurystheus invaded Attica to claim them by force, he was defeated and killed. Such were the main outlines of the legend, at least the Athenian legend (there was a Theban variant as well). Aeschy- lus had written a tragedy on the subject, and Athenian play- wrights loved to glorify an ancient Athens which had stood up for the weak and the oppressed (Aeschylus, The Eumen- ides; Sophocles, Oedipus at Colonus; Euripides, The Suppli- ants, Medea, Heracles). There are certain details which Euripides either invented or chose to emphasize. He is the first, as far as we know, to bring in the self-immolation of a daughter of Heracles. He also makes a major character out of lolaus, Heracles* nephew and old companion-in-arms, at the expense of Hyllus, the eldest of the Heracleidae. Some said Hyllus killed Eurystheus, others that lolaus did. Euripides makes Hyllus a son who is of fighting age, and the messenger's account of the battle gives him an honorable part, but Hyllus 127
