W. B. Yeats presented the mythological story of the relationship between Zeus and Leda in an artistic way. The Mother of Helen and Clytemnestra in Ancient Greek Mythology, Leda was seduced by Zeus who had transformed himself into a swan. The poem deals with both the event and the consequences of the event. A sonnet including an octave and a sestet, the poem narrates the event in the octave and comments on the consequences of the event in the sestet. Towards the end of the poem, Yeats is concerned with the relation of power to knowledge, both of which owned by Zeus and none of them adapted by Leda.
