are not wanting, which soil so darkly the path of his no less famous descendants. Pelops slew Myrtilus, the charioteer by whose aid he had won the race that was the beginning of his greatness; and it was the Fury of this Myrtilus--or "his blood crying to Heaven," as in Christian style we should express it--that, according to one poet (Eurip. Orest. 981), gave rise to the terrible retributions of blood by which the history of the Pelopidan family is marked. Of Pelops, according to the common account, Atreus and Thyestes were the sons. These having murdered their stepbrother, Chrysippus, were obliged to flee for safety to Mycenæ, in Argolis, where, in the course of events, they afterwards established themselves, and became famous for their wealth and for their crimes. The bloody story of these hostile brothers commences with the seduction, by Thyestes, of Aerope, the wife of Atreus; in revenge for which insult, Atreus recalls his banished brother, and, pretending reconciliation, offers that horrid feast of human flesh--the blood of the children to the lips of the father--from which the sun turned away his face in horror. The effect of this deed of blood was to entail, between the two families of Thyestes and Atreus, a hereditary hostility, the fruits of which appeared afterwards in the person of Ægisthus, the son of the former, who is found, in this first play of the trilogy, engaged with Clytemnestra in a treacherous plot to avenge his father's wrongs, by the murder of his uncle's son.
