De peste libri tres
A Latin treatise on plague by Jacques Dalechamps, printed in Lyon by Guillaume Rouillé in 1552 for physicians and medical readers. The single picture is a printer's device: an eagle with spread wings perched on a globe atop a pedestal, flanked by two serpents coiled below. A designer could take a compact, symmetrical emblem structure, with the eagle and serpents framing a central orb, as a model for a logo or seal.
