Pĕlŏpēa

, or Pĕlŏpīa , a daughter of Thyestes the brother of Atreus. She had a son by her father, who had offered her violence in a wood, without knowing that she was his own daughter. Some suppose that Thyestes purposely committed the incest, as the oracle had informed him that his wrongs should be avenged, and his brother destroyed, by a son who should be born from him and his daughter. This proved too true. Pelopea afterwards married her uncle Atreus, who kindly received in his house his wife’s illegitimate child, called Ægysthus, because preserved by goats ( αἰγες ) when exposed in the mountains. Ægysthus became his uncle’s murderer. See: Ægysthus . Hyginus , fable 87, . — Ælian , Varia Hist or i a , bk. 12 .— Ovid , Ibis , li. 359 .— Seneca , Agamemnon .
