| Orestes: son of Agamemnon and Clytaemnestra, brother of Electra.
When Agamemnon sacrificed his daughter Ipheginia to the gods for success in the Trojan War, Clytaemnestra sought revenge. First, she took up a younger, more caring lover. Then, when Agamemnon came home (with Cassandra forced into being his concubine), she killed him.
Electra convinces her younger brother Orestes to then kill their mother Clytaemnestra as revenge. He does so, but is tormented by the Harpies for the sin of matricide. He is then taken before the court of Olympus, and put on trial. Arguing against him is Athena, goddess of wisdom. In his defence is Apollo, god of sun, medicine, etc. Athena makes a good argument that this is matricide, a crime punishable by eternal torment in Tartarus.
However, Apollo makes the following argument: a human is only the offspring of the father, of his seed. The woman is merely an incubator for this seed, and contributes no genetic material (they didn't call it that, but that's what is essentially meant). Since there is nothing of the mother in the child, the child has no obligations to this biped hot-house, and Orestes cannot have committed matricide. A child's duty is to his father, not his mother. With this argument, Orestes is freed from his sin, and women are further considered merely a baby factory.
Long life Clytaemnestra! |
