A psychological-historical novel that re-tells of the story of the House of Atreus from Aeschylus' trilogy The Oresteia. As the story unfolds, contemporary themes are struck about mothers and daughters, femininity and masculinity, intergenerational transmission of trauma, the Oedipus complex, and the Electra complex. These and other themes emerge naturally in the narrative relevant to contemporary feminism, gender studies, psychology, classical studies, and historical reconstruction. The story unfolds from the very different perspectives of Clytemnestra and Electra, mother and daughter. Interspersed chapters are narrated by the Eumenides/Furies who offer different accounts of the story first as told in classic Greece and then an earlier version based on the pre-historical, matrifocal era. Clytemnestra's Last Day will be of interest to students of gender studies, classics, history, literature, theater and performing arts, psychology, psychoanalysis, and philosophy.
