An Explanation of the Natural Philosophers' Tincture: Now Available!
This manuscript concerns the chemical components of alchemy more than the actual crafting of any sorcerers' stone or elixir itself; indeed, it is the general recipe for the precursor materials needed to work the great work itself. The formula is fairly explicit but most of the secondary content used to "prove" the point is religious in nature and heavily metaphorical. Overall, a fine alchemical work of note, from one of the less well known figures within the period. It is slightly similar to some of Hollandus' work.
