Black beauty, which above that common light, <br />Whose Power can no colours here renew <br />But those which darkness can again subdue, <br />Do'st still remain unvary'd to the sight, <br /> <br />And like an object equal to the view, <br />Art neither chang'd with day, nor hid with night <br />When all these colours which the world call bright, <br />And which old Poetry doth so persue, <br /> <br />Are with the night so perished and gone, <br />That of their being there remains no mark, <br />Thou still abidest so intirely one, <br />That we may know thy blackness is a spark <br />Of light inaccessible, and alone <br />Our darkness which can make us think it dark.<br /><br />Lord Edward Herbert of Cherbury<br /><br />http://www.poemhunter.com/poem/sonnet-of-black-beauty/
