Thyestes- Greek FigureMortal"King of Mycenae"

The Golden Lamb

Thyestes was born to Pelops and Hippodamia, heir to a bloodline already cursed by his grandfather Tantalus, who had carved up his own son and served him to the gods. The taint resurfaced in the rivalry between Thyestes and his brother Atreus over the throne of Mycenae. When a golden-fleeced lamb appeared in Atreus's flock — a portent of divine favor and rightful kingship — Thyestes seduced Atreus's wife Aerope and persuaded her to steal the lamb and deliver it to him. He presented the fleece before the Mycenaean assembly as proof of his claim.

Zeus settled the matter by reversing the course of the sun, a sign that Atreus was the true king. Thyestes was driven into exile, but Atreus's fury only deepened when he discovered the adultery behind the theft.

The Feast and Its Aftermath

Atreus feigned reconciliation, sending word that his brother should return with his sons for a banquet at Mycenae. Thyestes came, hoping the feud was ended. Atreus had already slaughtered the boys — he butchered their bodies, boiled and roasted the flesh, and served it to their unknowing father at a lavish table. Thyestes ate his fill. When the meal was done, Atreus produced the children's heads and hands on a covered platter, revealing what his brother had consumed.

Thyestes overturned the table and fled, calling down a curse of unending bloodshed upon his brother's line. He consulted the Delphic oracle, which gave a terrible instruction: to gain his vengeance, he must father a child upon his own daughter. He found Pelopia performing nocturnal rites to Athena at Sicyon and forced himself upon her without revealing his identity. The child of this union was Aegisthus, raised unknowingly in Atreus's own household. When the truth of his parentage came to light, Aegisthus killed Atreus and restored Thyestes briefly to the Mycenaean throne — though Agamemnon soon drove him into a final exile from which he never returned.
