"O no! it is an ever-fixed mark
 That looks on tempests and is never shaken; 
 It is the star to every wandering bark,
 Whose worth's unknown, although his height be taken."
 
 [William Shakespeare, 'True Love']

Eliot once explained (to Philip Mairet, 31 October, 1956; the collection of Violet Welton)
that, even if a poem meant different things to different readers, it was still necessary
to assert its "absolute" meaning.  [Peter Ackroyd, 'T.S. Eliot: A Life']

"Once out of nature I shall never take
 My bodily form from any natural thing,
 But such a form as Grecian goldsmiths make
 Of hammered gold and gold enamelling
 To keep a drowsy Emperor awake;
 Or set upon a golden bough to sing
 To lords and ladies of Byzantium
 Of what is past, or passing, or to come."
 
- WB Yeats, 'Sailing to Byzantium'
