The mirror held your fair, my Fair, <br />A fickle moment's space. <br />You looked into mine eyes, and there <br />For ever fixed your face. <br /> <br />Keep rather to your looking-glass <br />Than my more constant eyes: <br />It told the truth - Alas! my lass, <br />My faithful memory lies.<br /><br />Hilaire Belloc<br /><br />http://www.poemhunter.com/poem/the-mirror-50/
