How does perspective change during renaissance from the prior medieval art?

The transition from the Middle Ages to the Modern Age was marked by changes in Europe: trade intensified, as cities developed, a bourgeoisie became a very powerful social group, while a nobility and a client lost prestige. And, of course, these changes cause new ways of living and thinking in the world, or that result in a broad artistic and scientific movement called the Renaissance.

The development of new tools (eg paints, brushes, mortars), a better understanding of nature, anatomy, mathematics, the use of concepts such as "light and shadow" and perspective allowed these artists to create works (painting, sculpture, architecture, literature) that brilliantly expressed this new European mentality: dynamic, grandiose, naturalistic and anthropocentric.

All the transformations in the field of the arts aroused the interest of the bourgeoisie, who saw in this new proposal a mirror of their own values, and for this reason, many bourgeoisie started to sponsor the artists, being called patrons (protectors of the arts).
