Shakespeare's Birthday

Not from the stars do I my judgment 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 aught 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.
