Like beautiful bodies of the dead, who had not grown old 
and they shut them with tears, in a magnificent mausoleum, 
with roses at the head and jasmine at the feet -- 
that is how desires look that have passed 
without fultillment; without one of them having achieved 
a night of sensual delight, or a moonlit morn.
Constantine P. Cavafy
