Backyard of the royal palace of Mycenae. The maids comment on the
strange and sullen conduct of Electra, daughter of Agamemnon, who
has left the family home after his death to live her pain apart
from everyone, rejecting human contact. When he is alone, Electra
exposes the objective of his existence: avenge his father, killed
by his wife Clitemnestra and his lover Egisto on his return from
the Trojan War. For this he trusts his brother Orestes, who remains
missing and who waits to help him consummate his desires.
Crisotemis, the younger sister of Electra, appears who tries to
prevent her against the plan of her mother and her lover: lock her
up to avoid her accusative attitude. Resigned to the death of her
father, Crisotemis only wishes she could lead a normal life, join a
man and have children. She implores Electra to give up her attitude
and returns to the palace after preventing her against her mother,
who is very disturbed by a dream that torments her.
Pale and jeweled, Clitemnestra makes its appearance. The queen
looks suspiciously at her daughter, but insists on being alone with
her and makes her part of his nightmares, which undermine her
existence. Electra advises him to make a human sacrifice to end his
torment, and describes with deletion that that sacrifice has to be
the death of Clitemnestra herself, at the hands of Orestes. The
terrified woman is immobilized by panic, but changes her attitude
when her trusted lady appears and whispers something in her ear.
Then he orders to illuminate the palace and leaves the courtyard
with a triumphant gesture.
A piercing scream takes Electra out of her confusion: it is
Crisotemis, who announces to Electra the death of Orestes, trampled
by her horses. Electra goes from initial despair to deciding that
both have to be the avengers of Agamemnon, and tries in vain for
her sister to join her purposes, being dejected and alone.
A young man appears in the courtyard and expresses his desire to
see the queen. Electra receives him with distrust, but he confesses
that Orestes is alive, and ends up showing himself as his brother,
who comes to avenge his father. She urges him to consummate his
purpose, and shortly after he hears the cry that announces the
death of Clitemnestra at his hands.
The patio is dark and silent. Egisto arrives and is surprised when
he sees the conciliatory attitude of Electra, which lights his way
and urges him to enter the palace so that he can celebrate the
death of Orestes. After crossing the door, his cries for help are
heard while he is killed.
Crisotemis arrives joyful: his brother is alive and the murderers
dead. He urges Electra to join the celebration, but she gives
herself to a dance of wild happiness and falls dead before her
