our stone according to Hollandus

The White Stone of Urine - Forums

our Stone costs little and can easily be found everywhere, in all street corners, in all secret chambers; on dung heaps and in caverns and vaults or in stables, there is an abundance of it.

It grows and greens in all places where its water is found and where it lies quietly. Our Stone also grows out of the foul, stinking Materi in which it is white and clear, just as glass grows out of the foul earth and is also beautiful and clear.

Therefore the ancients and wise men write: Our Stone purified itself and separates itself from all uncleanliness. The ignorant ones, who do not understand this, rebuke the ancients for having said this, and believe that it is mercury. And further, our Stone rises above all Faeces and ascends up high, where it collects.
