Offenbarung der Natur vnnd Natürlicher Dingen, auch mancherley subtiler würckungen
A 1559 German treatise on natural science and curious natural phenomena, attributed to Girolamo Cardano and Heinrich Pantaleon and printed by Petri, probably for scholars and curious readers. Its pictures are woodcut decorative initial letters with dense interlaced flourishes and scrolls, plus one plain geometric diagram of a triangle with labelled points, which a designer could draw on for ornamental lettering and simple line-based schematic work.
