I’m also currently doing some research into the Greek myths that enmesh the Trojan War (because Greek myths are fucking great). I just found this devastating poem by Yeats about Leda’s rape by Zeus when he appeared to her in the form of a swan. She subsequently gave birth to his daughter, the infamous Helen, and Cassandra, who would murder her husband Agamemnon for sacrificing their daughter Iphigenia.
Leda and The Swan
A sudden blow: the great wings beating still
Above the staggering girl, her thighs caressed
By the dark webs, her nape caught in his bill,
He holds her helpless breast upon his breast.
How can those terrified vague fingers push
The feathered glory from her loosening thighs?
And how can body, laid in that white rush,
But feel the strange heart beating where it lies?
A shudder in the loins engenders there
The broken wall, the burning roof and tower
And Agamemnon dead.
Being so caught up,
So mastered by the brute blood of the air,
Did she put on his knowledge with his power
Before the indifferent beak could let her drop?
W. B. Yeats, 1865– 1939
