During the lecture, Professor Plesch emphasized how important the study of perspective was to the progression of art. This almost required a scientific approach to art with some of the cutting edge ideas of the day, including the study of geometry. The philosophies surrounding art were much different than those today. Modern attitudes towards the arts see them as an expressive medium, were imitation is considered one of the least creative things. This differs greatly from how people thought about art for hundreds of years, from antiquity to the Renaissance. Here imitation and expressing the external world to the best of the artists ability were seen as the main goals to make enjoyable art, as nature was seen as one of the most perfect things. This imitation led to in depth studies of nature and the workings of the world, much like what the natural philosophers of the day were studying. I always find it interesting to see as philosophers moved towards the natural sciences, the art of the time period became more and more precise. Today, for most people, art and science are seen as opposite ends of a spectrum, but in the days of mimesis, they were almost on the same level and were sometimes using the same tools to study the same things.
