Source-derived summary

Aegisthus (; Ancient Greek: Αἴγισθος, romanized: Aigisthos, lit. 'goatherd' or 'sustained by a goat'; [ǎi̯ɡistʰos]) was a figure in Greek mythology. Aegisthus is known from two primary sources: the first is Homer's Odyssey, believed to have been first written down by Homer at the end of the 8th century BC, and the second from Aeschylus's Oresteia, written in the 5th century BC. Aegisthus also features heavily in the action of Euripides's Electra (c. 420 BC), although his character remains offstage.

Family

Aegisthus was the son of Thyestes and Thyestes's own daughter Pelopia, an incestuous union motivated by his father's rivalry with the house of Atreus for the throne of Mycenae. Aegisthus murdered Atreus in order to restore his father to power, ruling jointly with him, only to be driven from power by Atreus's son Agamemnon. In another version, Aegisthus was the sole surviving son of Thyestes after Atreus killed his brother's children and served them to Thyestes in a meal.

While Agamemnon laid siege to Troy, his estranged queen Clytemnestra took Aegisthus as a lover. The couple killed Agamemnon upon the king's return, making Aegisthus king of Mycenae once more. Aegisthus ruled for seven more years before his death at the hands of Agamemnon's son Orestes.

Mythology

Early life

Thyestes felt he had been deprived of the Mycenean throne unfairly by his brother, Atreus.

Editorial summary

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 224-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Aegisthus, Thyestes and Greek providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Aegisthus”, the useful work is to connect “son of Thyestes in Greek mythology” to the records capable of establishing context and consequence.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 9, 2026.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
