One of the most significant contributions of Western culture to the world during these years is that of the Renaissance. The Renaissance was a new artistic, philosophical, and political movement that changed the way in which Europe thought about itself and the world. The Renaissance emphasized the importance of the individual, and that of human experience, as opposed to the afterlife. This led to the study of humanity and human experience. An example of a Renaissance thinker is Leonardo da Vinci. Da Vinci studied humanity with an anatomical and physiological approach. However, he also looked at humanity from an artistic and emotional perspective. Many artists and thinkers such as Da Vinci were only able to complete their work due to the support of patrons. Patrons were wealthy people who invested their money in financing the works of artists, thinkers and other people of talent.
