In this edition of Sophocles' Electra, one of the greatest tragedies in Greek or any literature, Mr Keels presents the play as a study in revenge, but a subtle whose meaning depends upon the continuous use of dramatic irony. He relates the confrontations of principle and character depicted to the social and political controversies of the period in which Sophocles was writing. The introduction describes the background to the play, explains some of the main features of Sophocles' style, and outlines an interpretation which is fully worked out in the detailed commentary. There are appendices on metre and the text. The edition is intended for use by senior school and undergraduate students, and all those concerned to read and appreciate the play in the original.
