Der längst gewünschte und versprochene chymisch-philosophische Probier-Stein
A German alchemical and philosophical treatise published in 1740 by Michael Blochberger, attributed to Hermann Fictuld, and written for readers interested in chymical philosophy. Its pictures are letterpress-era woodcuts and engravings: a heraldic crest framed by an arched architectural niche with a tiled floor, a black-letter text page with a decorated initial, and a dense woodcut bouquet of flowers and fruit; a designer could draw on the heraldic framing, the Fraktur lettering and the botanical ornament.
