Images of mechanical prosthetics as designed by Ambroise Paré in his book Dix livres de la chirurgie (Ten books of Surgery). Paré was the official royal surgeon for kings Henry II, Francis II, Charles IX and Henry III and is considered to be one of the fathers of surgery and modern forensic pathology. As well as a designer of surgical instruments, he was also a leader in surgical techniques and battlefield medicine, especially the treatment of wounds. (Wikipedia)
