Galen: Healing with Blood, Sweat, and Ego
Galen’s patients tasted his treatments twice—once in the wound, and once in the biting debate that followed.

Medicine as Theater
Galen didn’t just treat the body—he dazzled the mind. He performed dissections in public, sparring with critics and delighting the Roman elite. Every wound was proof of theory—every cure, a boast.
The Medical World He Inherited—and Remade
Rome's medicine was a tangle of superstition and borrowed Greek science. Galen brought method, experiment, and endless debate. He argued so ferociously that emperors, soldiers, and gladiators alike lined up to be treated, or at least to watch the show.
A Legacy of Certainty—and Blind Spots
For centuries, doctors treated his words as law. Yet Galen’s confidence blinded medicine to new discoveries. Not until the Renaissance would his errors bleed out of Western science.
Galen made a spectacle of medicine—dissecting monkeys in front of crowds, arguing furiously with rivals, and insisting his theories trumped all. His blend of showmanship and certainty shaped medicine for 1,400 years. Sometimes he was right, sometimes dangerously wrong.
