Science were considered important during the Renaissance period, which as a result Leonardo was vastly ahead of his time. His approach to science was not theoretical, but rather more observational. Da Vinci sketched discrete diagrams of the human skeleton, muscles, sinews, the vascular system and genitalia. On the other hand, Leonardo also dissected and studied the structure of amphibians such as birds and a couple of mammals like horses and cows. Every human muscle would be dissected and was tugged and pulled in order for da Vinci to understand how it functioned. He then went on to create a model of the legs made of copper wires connected to the bones in order to make a skeleton. To this extent, Leonardo da Vinci deserves the title as being the “true Renaissance man” due to fact that not only did he studied the human body system, but also conducted research on amphibians and
