On Sugar and her Sweetness

Those, Cynthia, that do taste the honey-dew
Of thy moist rosy lips (who are but few).
Or sucketh vapour of thy breath more sweet
Than honeysuckle's juice, they all agree 't
To be Madeira's sugar's quintessence.
Or some diviner syrup brought from thence.
And for the operation, they believe,
It hath a quality provocative :
For Venus in the sugar's propagation
Is said to have a sovereign domination :
But I must not think so, for I have read
Of an extracted sugar out of lead.
Of which I once did taste, which chemists call
Sugar of Saturn, for they therewithal
Cure all venereal heats, for it doth hold
A winter in it like that Planet's cold,
And though 't be strangely sweet, yet doth it quench
All courage towards a mistress or a wench.
Such must I think thy sweetness for to be,
By that experience that is found in me :
For he that shall those sweets of thine but taste.
Shall like thyself become, as cold, as chaste :
For like the mildew new fallen from the sky,
Though dropt from Heaven, yet doth it mortify.
