Metals may blazon common beauties; she
30Makes pearls and planets humble heraldry.
As, then, a purer substance is defined
But by a heap of negatives combined,
Ask what a spirit is, you'll hear them cry
It hath no matter, no mortality:
So can I not define how sweet, how fair;
Only I say she 's not as others are.
For what perfections we to others grant,
It is her sole perfection to want.
