"The Renaissance"

Explanation:

Renaissance is the name given in the nineteenth century to a broad cultural movement that took place in Western Europe during the fifteenth and sixteenth centuries. It was a period of transition between the Middle Ages and the beginnings of the Modern Age. Its main exponents are in the field of arts, although there was also a renewal in science, both natural and human. The city of Florence, in Italy, was the birthplace and development of this movement, which later spread throughout Europe.

The Renaissance was the result of the dissemination of the ideas of humanism, which determined a new conception of man and the world. The term "rebirth" was used to claim certain elements of classical Greek and Roman culture, and was originally applied as a return to the values of Greco-Roman culture and the free contemplation of nature after centuries of predominance of a more rigid type of mentality and dogmatic established in medieval Europe. In this new stage a new way of seeing the world and the human being was proposed, with new approaches in the fields of arts, politics, philosophy and sciences, replacing medieval theocentrism with anthropocentrism.
