Historical Context
Atreus comes from the Greek name Ἀτρεύς. In Greek mythology, Atreus was a king of Mycenae, son of Pelops and father of Agamemnon and Menelaus. His bitter conflict with his brother Thyestes became central to the tragic stories of the House of Atreus, retold by ancient Greek writers and later dramatists. The name has therefore endured chiefly through classical literature and mythology rather than continuous everyday use.
