Fiery Water

But of this secret mercury; if you desire,
the secret for to learn, attend to me:
For this is a water which yet is fire,
which conquers bodies from their degree,
and makes them fly much like a spirit pure,
and this after fixing all flames to endure.

This water it doth flow from a fourfold spring,
which is but three, which two, and which but one,
is the only bath to bathe our king,
This is our maydew, this our flying stone;
our bird of Hermes in the mountains flying,
and without voice or note is always crying.

Marrow of Alchemy, George Starkey
