Unfathomable Sea! whose waves are years, <br />Ocean of Time, whose waters of deep woe <br />Are brackish with the salt of human tears! <br />Thou shoreless flood, which in thy ebb and flow <br />Claspest the limits of mortality, <br />And sick of prey, yet howling on for more, <br />Vomitest thy wrecks on its inhospitable shore; <br />Treacherous in calm, and terrible in storm, <br />Who shall put forth on thee, <br />Unfathomable Sea?<br /><br />Percy Bysshe Shelley<br /><br />http://www.poemhunter.com/poem/time-4/
