Controversiarum medicarum et philosophicarum libri decem.
Controversiarum medicarum et philosophicarum libri decem is a 1582 medical and philosophical treatise by Francisco Valles, printed at Frankfurt am Main by the heirs of Andreas Wechel for a learned readership of physicians and scholars. Its pictures are woodcut printers' devices and ornaments: a winged horse above caduceus and palm branches over a cloud-wreathed cartouche, and a Mannerist frame of scrolls, putti and caryatid figures that a designer could borrow for emblem or title-page layouts.
