Correspondingly, how did Atreus get revenge on Thyestes?
Thyestes agreed to give the kingdom back when the sun moved backwards in the sky, a feat that Zeus accomplished. Atreus retook the throne and banished Thyestes. Atreus then learned of Thyestes' and Aerope's adultery and plotted revenge. He killed Thyestes' sons and cooked them, save their hands and heads.
Also, what happened during the conflict between Atreus and Thyestes? Brief Summary There's all kinds of bad blood between Atreus and his brother Thyestes (and by bad blood we mean awful, terrible, horrific blood). Thyestes sparks the feud by sleeping with his brother's wife, stealing his golden fleece, and sneakily taking the throne of Mycenae from him.
Similarly, you may ask, what crime did thyestes commit?
According to one version of the story, Agamemnon and Menelaus—sons of Atreus and Aërope—found Thyestes at Delphi and imprisoned him at Mycenae. Aegisthus was sent to murder Thyestes, but each recognized the other because of the sword that Pelopia had taken from her father and given to her son.
