Raimundi Lulli ... de secretis naturae sive quinta essentia libri duo : his accesserunt Alberti Magni ... de mineralibus & rebus metallicis libri quinque
A 1541 alchemy treatise by Ramon Llull with Albertus Magnus's writings on minerals, edited by Walther Ryff and printed by Beck, drawn from a library formerly owned by C.G. Jung. The pictures are crisp woodcuts of glass alembics, flasks and vessels set against tiled floors and arcaded courtyards, with simple ruled frames and dense black-letter text. A designer could draw on their clean outline drawing, hatched shading and geometric tile patterns.
