HOUSE OF ATREUS AND THEBAN CYCLE (seven against Thebe)

Cadmus Sowing the Dragon's teeth, by Maxfield Parrish, 1908

In between the Argo and the Trojan War, there was a generation known chiefly for its horrific crimes. This includes the doings of Atreus and Thyestes at Argos. Behind the myth of the house of Atreus (one of the two principal heroic dynasties with the house of Labdacus) lies the problem of the devolution of power and of the mode of accession to sovereignty. The twins Atreus and Thyestes with their descendants played the leading role in the tragedy of the devolution of power in Mycenae.

The Theban Cycle deals with events associated especially with Cadmus, the city's founder, and later with the doings of Laius and Oedipus at Thebes; a series of stories that lead to the eventual pillage of that city at the hands of the Seven Against Thebes and Epigoni. (It is not known whether the Seven Against Thebes figured in early epic.) As far as Oedipus is concerned, early epic accounts seem to have him continuing to rule at Thebes after the revelation that Iokaste was his mother, and subsequently marrying a second wife who becomes the mother of his children — markedly different from the tale known to us through tragedy (e.g. Sophocles' Oedipus the King) and later mythological accounts.
