Human anatomy, by Leonardo Da Vinci (1509-1510)At a time in history when few people had methodically attempted to document human anatomy both inside and outside the body, Renaissance artist Leonardo Da Vinci did both. He produced over 200 drawings, based on dissections he observed, of human musculature and skeletal structure. Not only were these images beautiful, but they were among the most accurate medical diagrams created in Europe up to that point. By combining scientific observation with his art, Da Vinci helped to invent modern anatomy studies.
