"In Greek mythology, Aethra or Aithra (Ancient Greek: Αἴθρα, pronounced [ǎi̯tʰra], English: /ˈiːθrə/, the "bright sky") was a daughter of King Pittheus of Troezen and the mother of Theseus (his father was King Aegeus of Athens, or in some versions, Poseidon) and of Clymene (by Hippalces). Aethra was also called Pittheis after her father Pittheus." - (en.wikipedia.org 01.01.2020)
