 In most accounts of this event, Helen was quite young; Hellanicus of Lesbos said she was seven years old and Diodorus makes her ten years old.On the other hand, Stesichorus said that Iphigenia was the daughter of Theseus and Helen, which obviously implies that Helen was of childbearing age.In most sources, Iphigenia is the daughter of Agamemnon and Clytemnestra, but Duris of Samos and other writers followed Stesichorus' account.
