Hyginus Fabulae, 92.4-5 Judgment of Paris.

[The ParisHelen are these:]      Paris preferred the last gift to the first two and he judged Venus to be the fairest; for this reason Juno and Minerva were hostile to the Trojans. Alexander was subject to Venus' drive when he abducted Helen from Sparta, even from his host Menelaus, and he led her off to Troy. He kept her as his wife tended to by two maids, Aethra and Thisadie, two captives Castor and Pollux had granted him who once had been queens.

     92. Paridis Iudicium
      ...Paris donum posterius prioribus anteposuit, Veneremque pulcherrimam esse iudicauit; ob id Iuno et Minerua Troianis fuerunt infestae. Alexander Veneris impulsu Helenam a Lacedaemone ab hospite Menelao Troiam abduxit eamque in coniugio habuit cum ancillis duabus Aethra et †Thisiadie, quas Castor et Pollux captiuas ei assignarant, aliquando reginas.
