Origins
Leda and the Swan was a Greek myth in which the God Zeus transformed into a swan and raped the girl Leda.
Different versions of the myth disagree on whether Leda was actually raped or seduced by Zeus.
In the myth, Leda gave birth to four children, who hatched from eggs. One of the children was Helen of Troy, the woman the Trojan War was fought over.

It has three stanzas, and line 11 is broken off into two lines. Yeats uses three stanzas to distinguish the internal divisions in the poem. Line 11 is broken up in order to heighten the drama of Agamemnon being dead and to show how the poem shifts back to Leda's perspective after leaping forward into the future.
