Circulus anatomico-physiologicus :
Circulus anatomico-physiologicus is a 1686 Latin medical treatise on physiology and comparative anatomy, written by Johannes Bohn and Marcello Malpighi and printed in Leipzig for a learned readership of physicians and naturalists. The three pictures are decorative letterforms and a printed ornamental cartouche: a large foliated initial C with dense scrollwork, a second ornamental initial C beside Latin text, and a symmetrical fruit-and-acanthus headpiece. A designer might take from them the dense interlaced scrollwork of baroque initials and the balanced, fruit-filled symmetry of early modern book ornament.
