Atreus

Atreus, in Greek mythology, son of Pelops. When the king of Mycenae died without an heir, the notables of the kingdom chose Atreus as their new king. Atreus's brother Thyestes, a rival for the throne, seduced Aërope, wife of Atreus and mother of Agamemnon and Menelaus. In revenge, Atreus murdered two of Thyestes' sons and served them boiled in a cauldron to their father at a banquet. When Thyestes had eaten the loathsome meal, Atreus ordered a dish holding the bloody heads of the children brought in. Thyestes laid a curse on his brother. Atreus later married Pelopia, daughter of Thyestes, not knowing her true identity. Her son Aegisthus killed Atreus at the command of Thyestes.
