’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?’ Leda And The Swan, W.B. Yeats, 1924
