Erigone (daughter of Aegisthus)

In Greek mythology, Erigone (Ἠριγόνη) was the daughter of Aegisthus and Clytemnestra, rulers of Mycenae. Some accounts said that by her half-brother, Orestes, Erigone was the mother of Penthilus and Tisamenus.

Mythology
Erigone would have been slain by Orestes along with her brother Aletes if not for the intervention of Artemis, who rescued her and made her a priestess in Attica. In some stories, she hangs herself after the child is born, though this may be a confusion with Erigone, daughter of Icarius. Also, after Hermione died, she is said to have married Orestes and gave birth to Penthilus. Or it is said she sued Orestes for the murder of her parents.
