Aegisthus
The result
of an incestuous relationship between Thyestes and his daughter Pelopia. Pelopia
married her uncle Atreus, who did not know of their relation, and he took
Aegisthus as his own son.
When Aegistus later found out who he really was, he killed Atreus and soon
became the lover of Queen Clytemnestra while her husband king Agamemnon was
away at Troy.
Agamemnon had left Clytemnestra with a singer, and as long as the singer was
present, Clytemnestra resisted Aegisthus. Aegisthus then took the singer to
a deserted island, and Clytemnestra was seduced. On the kings' return after
the ten-year war, Aegisthus helped Clytemnestra kill Agamemnon, and after
this ruled Mycenae together with her for seven years.
He was eventually killed by Agamemnon's son Orestes.
