Galen's anatomy combines observation with analogy
Animal dissection and clinical experience supported Galen's influential anatomy, but extending animal structures to humans also produced errors.
The story
In Rome, Galen investigated nerves, muscles and organs through anatomical demonstrations. His extensive writings offered a persuasive medical system. There is no reliable evidence that he dissected human bodies, however, and species differences undermined some descriptions. Later Arabic and Latin traditions transmitted his work and developed resources for criticizing it.
Connections and context
Vesalius later compared written descriptions directly with human anatomy. Historical influence and the accuracy of individual conclusions are separate questions.
