Gaffarillus. An Alchemist and philosopher who lived in the middle of the seventeenth century. He is the first philosopher known to maintain that every natural object (e.g., plants, living creatures, etc.), when burned, retained its form in its ashes and that it could be raised again from them. This claim was justified by the eminent chemist Du Chesne, and after him Kircher, Digby and Vallemont have assured themselves of the fact, by demonstrating that the astral forms of burned plants could be raised from their ashes. A receipt for raising such astral phantoms of flowers is given in a work of Oetinger, Thoughts on the Birth and Generation of Things.
