Allegory and the Tragic Chorus in Sophocles' Oedipus at Colonus

In this book, Roger Travis brings together poetics and psychology to study the tragic chorus in Sophocles' Oedipus at Colonus. Beginning from Quintilian's definition of allegory as extended metaphor, Travis argues that in Oedipus at Colonus the chorus of old men forms an allegorical relationship with the aged Oedipus, which depends in turn upon the chorus's own likeness to the Athenian audience.
