A SUDDEN blow: the great wings beating still <br />Above the staggering girl, her thighs caressed <br />By the dark webs, her nape caught in his bill, <br />He holds her helpless breast upon his breast. <br />How can those terrified vague fingers push <br />The feathered glory from her loosening thighs? <br />And how can body, laid in that white rush, <br />But feel the strange heart beating where it lies? <br />A shudder in the loins engenders there <br />The broken wall, the burning roof and tower <br />And Agamemnon dead. <br />Being so caught up, <br />So mastered by the brute blood of the air, <br />Did she put on his knowledge with his power <br />Before the indifferent beak could let her drop?<br /><br />William Butler Yeats<br /><br />http://www.poemhunter.com/poem/leda-and-the-swan/
