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

The art of this period is familiar, since the world of the Realists, Impressionists and Post-Impressionists is much like our own. More and more people lived in cities and worked in factories or shops for wages. Scientific and technological advances increased dramatically during this period and although there was dislocation and privation, standards of living increased sharply. In essence, modern mass culture was born. Artists responded sometimes by embracing these radical changes, and at other times by resisting them. Key here is understanding the authority of the various art academies in Europe, which controlled matters related to taste and art, and which were, to some extent, always connected to the government. A small number of artists rebelled against the strictures of the academy, and against the demand for art to tell clear stories for a middle class audience, and formed what we know as the
