Ambroise Pare, born in France around 1510, was chief surgeon to both Charles IX and Henri III. In one of the first attempts to explain birth defects, Pare produced On Monsters and Marvels, an illustrated encyclopedia of curiosities, of monstrous human and animal births, bizarre beasts, and natural phenomena. Janice Pallister's acclaimed English translation offers a glimpse of the natural world as seen by an extraordinary Renaissance natural philosopher.
