This is a transitional period. In the art of Florence and Siena there is a move away from medieval abstract depictions of space and the human body as artists began to focus on the illusion of mass and space and the expression of human emotion. With hindsight, it is possible to trace elements of Renaissance art back to this period. This century saw the creation of the beautiful poetry of Dante and Petrarch, but it is also the century that saw the worst outbreak of the Bubonic plague (known then as the Black Death) which wiped out close to half the population of Europe

This is the century that sees the full realization of the Renaissance and the end of the medieval way of thinking about the world. The Humanist rediscovery of ancient Greek and Roman culture is supported by the wealth accumulated in prosperous cities such as Bruges, Florence, and Venice. New wealth and increasing trade created a demand for an art based on the world we see. The second half of the century saw the invention of the printing press, and Columbus

If there was one century in the past that saw radical changes in established ways of thinking comparable to the 20th Century, it would be the 16th. Before this, in Western Europe, there was only one type of Christianity

The 17th Century is the era of the Baroque style, characterized by energy, drama, and movement. The Church in Rome needed art that spoke to its resurgent power even as the conflict between Protestant and Catholics continued. A new realism
