The Kaibo Zonshinzu anatomy scrolls, painted in 1819 by Kyoto-area physician Yasukazu Minagaki (1784-1825), consist of beautifully realistic, if not gruesome, depictions of scientific human dissection.
Unlike European anatomical drawings of the time, which tended to depict the corpse as a living thing devoid of pain (and often in some sort of Greek pose), these realistic illustrations show blood and other fluids leaking from subjects with ghastly facial expressions.
