By Clytaemnestra, Agamemnon had three daughters, Iphigeneia (Iphianassa), Electra (Laodice), Chrysothemis, and a son, Orestes.
The murder of Agamemnon was avenged by his son Orestes.
In this new country it was her duty to sacrifice to the goddess all strangers; and as her brother Orestes came to search for her and to carry off to Attica the image of the goddess, she was about to sacrifice him, when a happy recognition took place.
Orestes and Iphigeneia fled, takini with them the image; at Delphi they met Electra, the sister of Orestes, who having heard that her brother had been sacrificed by the Tauric priestess, was about to tear out the eyes of Iphigeneia.
Another story is that a rock hung over his head ready to fall and crush him (Euripides, Orestes, 5).
