Andreas Vesalius was an anatomist and physician. He created a famous book (1543) of anatomical drawings named “De humani corporis fabrica” meaning Fabric of the Human Body. He was the one who realised that Galen’s work could not all be completely true as due to religious reasons Galen only dissected animals. He believed surgery was very important and dissected human bodies to study anatomy.
When I undertake the dissection of a human cadaver I pass a stout rope tied like a noose beneath the lower jaw and through the zygomas up to the top of the head… The lower end of the noose I run through a pulley fixed to a beam in the room so that I may raise or lower the cadaver as it hangs there or turn around in any direction to suit my purpose; … You must take care not to put the noose around the neck, unless some of the muscles connected to the occipital bone have already been cut away.
