For 10 points, what lover of Clytemnestra seized power while Agamemnon was  ghting at Troy?
In the Odyssey, Nestor relates that this man marooned a court bard on an island to be eaten by crows and seagulls. He was conceived when his mother, while washing clothes stained with the blood of a sacri cial ewe, was raped by a masked man, whose sword she managed to steal; as a child, this son of Pelopia (peh-LOH-pee-ah) was commanded to use that sword to murder a prisoner revealed to be his own father, Thyestes ("thigh"-ESS-teez), leading him to kill Atreus (AY-tree-us) instead. This man's lover killed her husband by trapping him in a net and beheading him with an axe, motivated by anger at the sacri ce of her daughter Iphigenia; both that woman and this Mycenaean (my-SEE-nee-an) usurper were slain by Orestes, who was avenging his father.
