As detailed books where being written, lavishly illustrated and universities where using them to teach students, people began to look for a way to mass-produce books. The printing press was invented. With this colossal improvement copies of new books could be distributed all over Europe, as well as the new books old books such as the works of Galen could be viewed by everyone. People where really starting to think about things.
With all this wealth around it is only human nature to want more, as a result several wars broke out during the 13th century. However, the renaissance managed to bring good from these wars. Surgeons like Pare were put under immense pressure; this forced them to find better ways of doing things.
Away from the battlefield people set their creative minds to inventing. Watches clocks and pumps were all created. People looked at the machines and the human body and saw that there isn’t much difference. William Harvey realised that the water pump performs a similar job to the heart, even though this went against the theories of ancient doctors, he still experimented with his ides by cutting open live reptiles to watch how the blood flowed trough the body.
A combination of great minds, technological advances, a decline in the Roman Catholic Church and experimenting and testing enabled the improvements to be made.
During the renaissance the painful and often lethal process of cauterising was replaced with ligatures. The process of boiling oil to heal wounds was replaced with ointments and bandaging. The human body was opened up for the entire world to see. And the circulatory system was uncovered.
But now people new where the heart was and how it worked, they still didn’t now how to cure fevers or prevent plagues so what good did the renaissance really do.
