William Shakespeare, Sonnet xix
Devouring Time, blunt thou the lion's paws, 
And make the earth devour her own sweet brood; 
Pluck the keen teeth from the fierce tiger's jaws, 
4
And burn the long-lived phœnix  in her blood; 
Make glad and sorry seasons, as thou fleets, 
And do whate'er  thou wilt, swift-footed Time, 
To the wide world, and all her fading sweets; 
8
But I forbid thee one most heinous crime: 
O carve not with thy hours my love's fair brow, 
Nor draw no lines there with thine antique pen; 
Him in thy course untainted do allow, 
12
For beauty's pattern to succeeding men. 
Yet, do thy worst, old Time: despite thy wrong, 
My love shall in my verse ever appear young.
