OíNeil is one of the greatest American dramatists. He is a prominent dramatist of modern age. He has really protested against the prevailing surface realism or naturalism. Mourning Becomes Electra is as itís suggest a play based on the Greek legend of Orestís as represented in the plays of Aeschylus, Euripides and Sophocles. The Greek overtones and the classical chastity lend a sort of tragic grandeur to this play. In this play OíNeil has recast the famous Greek legend of Agamemnon myth which has been so artistically presented in Aeschylus Orestea trilogy, Sophocles Electra and Euripides Electra in American social climate and Freudís emphasis on psychology.
The problem of OíNeil was how to adapt the Greek circumstances and story to modern American life. But as an inspired artist he exploited the parallel events in Greek and American life.
