Vesalius vs Galen
The Flemish physician, Andreas Vesalius, published this illustration of a human skull resting atop a dog’s skull in his ground-breaking book, "On the Fabric of the Human Body" in 1543. He liked this drawing enough that he used it as a chapter heading twice. You have to know a little bit about the history of anatomy to understand that Vesalius was being a cheeky bastard. Up until this time, most of our understanding of the internal workings of the human body was based on a 3rd Century Greek physician, Galen's dissections of dogs. I think Vesalius was pretty pleased with himself for demolishing Galen's theories.
