Classic Poem

With open shells in seas, on heavenly dew
A shining oyster lusciously doth feed,
And then the birth of that aethereall seed
Shews, when conceiv'd, if skies looke dark or blew:
So do my thoughts, caelestiall twins, of you,
At whose aspect they first begin and breed,
When they came forth to light, demonstrate true,
If ye then smil'd, or lowr'd in mourning weed.
Pearles then are orient fram'd, and faire in forme,
If heavens in their conceptions do look cleare;
But if they thunder, or do threat a storme,
They sadly darke and cloudy do appeare:
Right so my thoughts and so my notes do change,
Sweet if ye smile, and hoarse if ye look strange.
