For sale: De secretis naturae - Paul Ferguson - 04-09-2025
Second edition of this compilation (first edition was published in Strasbourg 1541), edited by Walther Ryff, and first edition published in Italy.
The first part is a treatise on the quintessence (pp. 1-107), being a Lullian version of the De consideratione quintae essentiae of Joannes de Rupescissa (first printed in Venice, 1514). Although spurious, this treatise had enormous influence on the development of alchemy and is regarded as one of the most authoritative texts on the quinta essentia. The second part comprises Albertus Magnus' De mineralibus, his principal work on mineralogy, metallurgy, and chemistry, dealing with stones, metals and "intermediates" which are neither stones nor metals, but have characteristics of both.
