Observationum medicinalium libri sex
Observationum medicinalium libri sex is a Latin medical casebook by physician François Valleriole, printed in Lyon by Antoine Gryphius in 1573, aimed at practising physicians and students of medicine. Its pictures are a printer's title-page cartouche with a winged creature perched on a block, a large decorated initial P with a small figure beside it, and dense text pages with small marginal headings, showing how a sixteenth-century scholarly page balanced ornament, type and white space.
