S ulphur is not the last amongst the Principles, because it is a part of the Metall; yea and the principall part of the Philosophers Stone: and many wise men have left in writing divers, and very true things of Sulphur. Yea Geber himself in his first book of the highest perfection, cha. 28. saith: Through the most High God it illuminates every body: because it is light from light, and Tincture. But before wee treate of it, it seems good to us to first describe the originall of the Principles; especially since of old, Sulphur hath been accounted the chiefest of the Principles. Now very few have hitherto shewed whence the Principles arise, and it is a hard thing to judge of any of the Principles, or anything else, whose originall, and generation is unknowne: what can a blind man judg of a colour? What our predecessors have omitted, that have wee purposed in this Treatise to supply.
