Book excerpt: “A vibrant, original portrait of a man of contradictions,” the Renaissance-era Swiss father of modern medicine (Publishers Weekly, starred review). Philippus Aureolus Theophrastus Bombast von Hohenheim, who called himself Paracelsus, stands at the cusp of medieval and modern times. A contemporary of Luther, an enemy of the medical establishment, a scourge of the universities, an alchemist, an army surgeon, and a radical theologian, he attracted myths even before he died. His fantastic journeys across Europe and beyond were said to be made on a magical white horse, and he was rumored to carry the elixir of life in the pommel of his great broadsword. His name was linked with Faust, who bargained with the devil. Who was the man behind these stories? Some have accused him of being a charlatan, a windbag who filled his books with wild speculations and invented words. Others claim him to be the father of modern medicine. Philip Ball exposes a more complex truth in The Devil’s Doctor—one that emerges only by entering Paracelsus’s time. He explores the intellectual, political, and religious undercurrents of the sixteenth century and looks at how doctors really practiced, at how people traveled, and at how wars were fought. For Paracelsus was a product of an age of change and strife, of renaissance and reformation. And yet by uniting the diverse disciplines of medicine, biology, and alchemy, he assisted, almost despite himself, in the birth of science and the emergence of the age of rationalism. Praise for The Devil’s Doctor “An enlivening portrait that will spark interest in [Paracelsus’s] role in the rise of science.” —Booklist “A true iconoclast, [Paraclesus] inhabited an ideological landscape somewhere between the medieval and the modern. Ball effectively places Paracelsus in the larger context of Renaissance magic and philosophy, and of a turbulent period. . . . Worth the effort.” —Kirkus Reviews
