Castor and Pollux were called the Dioscuri meaning “Zeus’s sons,” even though Castor was mortal because he was the son of Tyndareus and Pollux was immortal because he was the son of Zeus. According to Hermes in Lucians’ "The Dialogues of the Dead", Leda and her daughter (Helen of Troy) are the only women worthy of the title “beauties of old.” Rubens’s depictions of Leda clearly embody the phrase. With Leda’s curvy figure, alabaster skin, and golden hair, she is a sight to behold.
Leda (mythology) not see her brothers among the Achaeans. The narrator remarks that they are both already dead and buried back in their homeland of Lacedaemon, thus suggesting that at least in the Homeric tradition, both were mortal. Another account of the myth states that Nemesis (Νέμεσις) was the mother of Helen, and was also impregnated by Zeus in the guise of a swan. A shepherd found the egg and gave it to Leda, who carefully kept it in a chest until the egg hatched. When the egg hatched, Leda adopted Helen as her daughter. Zeus also commemorated the birth of Helen
