there was a rise in humanism in the Renaissance period
they started to believe in exploration and experimentation especially in medicine

people returned to the texts of Galen and Hippocrates but new translations were being produced
more experimentation was being carried out as the Church had less authority, Galen was being proven wrong by more known in human anatomy through Vesalius
