William Shakespeare’s Sonnet XIV

Not from the stars do I my judgement pluck;   
And yet methinks I have astronomy,   
But not to tell of good or evil luck,   
Of plagues, of dearths, or seasons' quality;   
Nor can I fortune to brief minutes tell,   
Pointing to each his thunder, rain and wind,   
Or say with princes if it shall go well   
By oft predict that I in heaven find:   
But from thine eyes my knowledge I derive,   
And constant stars in them I read such art   
As 'Truth and beauty shall together thrive,   
If from thyself, to store thou wouldst convert';     
  Or else of thee this I prognosticate:     
  'Thy end is truth's and beauty's doom and date.'
