This work of seemingly conventional, philologically based criticism challenges many of the traditional views of Sophocles' Oedipus at Colonus. Joseph P. Wilson disputes the received wisdom that Oedipus was a suppliant of the Athenians, arguing rather that the primary relationship that governed Oedipus's dealings with his hosts was "xenia" (hospitality), not "hiketeia" (supplication), Likewise, he considers in detail the disputed reading of "empolin" or "empalin" in verse 637 and the vexed question of whether Oedipus ever became a citizen of Athens. He concludes by investigating the matter of Oedipus' heroic and oracular capabilities and the role that Oedipus' own will plays in creating his heroic persona. Wilson's study offers a radical rereading of the Oedipus riddle and concludes with a substantial discussion of the play's (and playwright's) role in providing a political and moral education for the troubled Athenian "polis" in the last decade of the tumultuous fifth century.
