Yon black man-of-war-hawk that wheels in <br />the light <br />O'er the black ship's white sky-s'l, sunned <br />cloud to the sight, <br />Have we low-flyers wings to ascend to his <br />height? <br />No arrow can reach him; nor thought can <br />attain <br />To the placid supreme in the sweep of his <br />reign.<br /><br />Herman Melville<br /><br />http://www.poemhunter.com/poem/the-man-o-war-hawk/
