The trilogy " mourning becomes Electra" dynamically combines not only ancient Greek tragedy but also contemporary theories of psychoanalysis, the puritanical culture of New England, and American history. This work is exciting in its plot and dynamically placed in time and space, while the stories and personalities of its characters are well-developed and crystal clear.

From the first confrontation between mother and daughter, Christine and Lavinia, in the First Part of the trilogy titled "The Return," the unfolding of the plot begins to twist and tighten like a huge python that will swallow all the members of the doomed Mannon House. The Mannon family members are driven to their self-destructive behavior by internal needs and compulsions that they can neither understand nor control.

O'Neill, in this fusion of Greek mythology and modern psychology, ultimately proved his prowess as a great global dramatist, creating the first true essence of his literary creation, which was undeniably the trilogy "mourning becomes Electra."
