leda's marriage to tyndareus is followed by the births of clytemnestra, timandra and phylonoe, the last of whom artemis made immortal. clytemnestra and agamemnon had two daughters, electra and iphimede, the name used in the poem for the woman later and more famously known as iphigenia. it had been prophesied that she must be sacrificed to artemis before the greek fleet could sail for troy, but in the "catalogue" version of events the goddess replaced her with an "eidolon" and immortalized iphimede as "artemis enodia", or hecate. next orestes' birth and matricide are reported, the earliest extant account of his killing clytemnestra, as the planned sacrifice of iphimede/iphigenia is first found in the "catalogue". timandra's marriage to echemus follows, followed in turn by leda's bearing the dioscuri to zeus in several damaged lines. it is unknown if helen's birth was reported here, for the testimonia leave her parentage uncertain. althaea lies with ares and bears meleager, whose heroic qualities are described along with his death at the hands of apollo during the conflict with the curetes that was the sequel to the hunt for the calydonian boar. among althaea's children by oeneus, deianeira is singled out for her role in the death and apotheosis of heracles. the poet next turns his attention to the porthaonids (see above) and closes out his account of the female aeolids with the sirens, daughters of sterope and achelous.
