Surgery and Science Go Hand in Hand

In the 1550s, Leonardo Fiorevanti performed surgery on a patient's spleen. He requested his spectators to relieve themselves into the patient's open abdomen. Skin grafting was actually more or less the same operations that farmers would perform just on plants. It was so close he called it transplant surgery, the agriculture of the body. And this seems like quite a normal approach to us now in a way. But back in the Renaissance, it was seen by medical authorities as quite backwards.
