Isaac Hollandus remains one of the foremost names within the realm of alchemy. This work proposes, among other things, that an alchemical cure-all can be made simply by processing lead with vinegar and other materials. The danger associated with alchemy is all the more real here, where the operator is admonished to taste test compounds containing heavy metals. Beyond this, it additionally admonishes the practitioner to heal the sick, do good to the poor, and praise the Christian god.
