The Greater and Lesser Edifyer contains much of interest to the student of Alchemy, including innumerable cross-references to other Alchemical works, and practical plus allegorical instructions on the practice of the Art. Johann Grasshoff (or Grasshof, Grasse) (1560 - 1623) was a Pomeranian jurist and alchemical writer. He is also recorded as a medical advisor to Ernest of Bavaria, an Episcopal counselor. His writings include the Aperta Arca arcani artificiosissimi (1617) and a Cabala Chymica (1658). The compilation of the 1625 Dyas chymica tripartita is also attributed to him; it includes The Golden Age Restored of Henricus Madathanus, The Book of Lambspring of Nicholas Barnaud, and the Book of Alze.
