AETHRA

daughter of Pittheus, king of Troezen, mother of Thresus by Aegeus. or, according to another account, by Poseidon. While Homer merely mentions her as a servant of Helen at Troy, later legend adds that, when the Dioscuri took Aphidnae and set free their sister whom Theseus had carried off, they conveyed Aethra to Sparta as a slave, whence she accompanied Helen to Troy; and that on the fall of that city, they brought her grandsons Acamas and Demophoon back to Athens.
