Mycenae was founded by Perseus, son of Zeus and Danae, and the Perseid dynasty provided many of its rulers. After the last of them, Eurystheus (famous for the labors he imposed on Herakles), the Mycenaeans chose Atreus, son of Pelops and Hippodamia, as their ruler.
But Atreus hated his brother, Thyestes, so much that he offered Thyestes his own children to eat, thereby incurring the wrath of the gods. Thyestes pronounced a fearful curse on Atreus and his progeny; Atreus's heir, the renowned and energetic Agamemnon, was murdered on his return from the Trojan War by his wife, Clytemnestra, and her lover, Aegisthus (Thyestes's surviving son).
Orestes and his sister Electra, the children of Agamemnon, took revenge for this murder, and Orestes became king of Mycenae.
During the rule of his son, Tisamenus, the descendants of Herakles returned and claimed their birthright by force, thus satisfying the wrath of the gods and the curse of Atreus. |
