Basilica chymica is a 1609 Frankfurt medical and pharmacological treatise by the German physician Oswald Croll, written in Latin for physicians and apothecaries, with an appended tract on the internal signatures of things. The pictures here are decorative woodcut initials, the large ornamental letter R with a figure, a small boxed A, and foliate C and S, whose scrolled acanthus borders suggest a designer's model for historic letterforms and frame ornament.
