Source A: The Fabric of the Human Body

"I have carefully dissected many bodies, and I have drawn the muscles, bones, and organs with precise accuracy, challenging the old authorities that relied on ancient texts. My detailed illustrations and direct observations aim to better understand human anatomy, which was previously misunderstood due to reliance on inaccurate copies of Galen's work. I believe that by studying the actual human body, medicine can progress beyond superstition and traditional beliefs. My work was intended to educate doctors and students, providing a more scientific basis for medicine." Provenance: Andreas Vesalius, 1543, Anatomical textbook
