Clavis sapientiae, das ist, Ein edles vnd köstliches Büchlein vom Stein der Weysen welcher genant wird, der Schlüssel der grössern Weissheit : voretlich hundert Jahren in Lateinischer Sprache beschreiben
A German translation of Artephius's alchemical tract on the philosophers' stone, printed by Peter Schmidt at Halle in Saxony in 1618 for readers of Latin alchemical literature. The only pictures are typographic ornament: a heart-shaped fleuron tailpiece of scrolling foliage and a stepped wedge built from repeated vine-and-leaf cast units, useful as inked, slightly misregistered borders, dividers and page-end stops.
