Name and describe three important artistic concepts developed by Renaissance artists.

The Renaissance, is a period in Europe, from the 14th to the 17th century, considered the bridge between the Middle Ages andmodern history. It started as a cultural movement in Italy in the Late Medieval period and later spread to the rest of Europe, marking the beginning of theEarly Modern Age.

The Renaissance's intellectual basis was its own invented version ofhumanism, derived from the rediscovery of classical Greek philosophy, such as that of Protagoras, who said, that "Man is the measure of all things." This new thinking became manifest in art, architecture, politics, science and literature. Early examples were the development of perspective in oil painting and the recycled knowledge of how to make concrete. Although the invention of metal movable type sped the dissemination of ideas from the later 15th century, the changes of the Renaissance were not uniformly experienced across Europe.

As a cultural movement, it encompassed innovative flowering of Latin and vernacular literatures, beginning with the 14th century resurgence of learning based on classical sources, which contemporaries credited to Petrarch; the development of linear perspective and other techniques of rendering a more natural reality in painting; and gradual but widespread educational reform. In politics, the Renaissance contributed to the development of the customs and conventions of diplomacy, and in science to an increased reliance on observation and inductive reasoning. Although the Renaissance saw revolutions in many intellectual pursuits, as well as social and political upheaval, it is perhaps best known for its artistic developments and the contributions of such polymaths as Leonardo da Vinci And Michelangelo, who inspired the term "Renaissance man".

There is a consensus that the Renaissance began in Florence, in the 14th century. Various theories have been proposed to account for its origins and characteristics, focusing on a variety of factors including the social and civic peculiarities of Florence at the time; its political structure; the patronage of its dominant family, the Medici, and the migration of Greek scholars and texts to Italy following The Fall of Constantinople at the hands of the Ottoman Turks. Other major centres were northern Italian city-statessuch as Venice, Genoa, Milan; Bologna; and finally Rome during theRenaissance Papacy.

The Renaissance has a long and complex historiography, and, in line with general scepticism of discreteperiodizations, there has been much debate among historians reacting to the 19th-century glorification of the "Renaissance" and individual culture heroes as "Renaissance men", questioning the usefulness ofRenaissance as a term and as a historical delineation. The art historian Erwin Panofsky observed of this resistance to the concept of "Renaissance":

It is perhaps no accident that the factuality of theItalian Renaissance has been most vigorously questioned by those who are not obliged to take a professional interest in the aesthetic aspects of civilization-historians of economic and social developments, political and religious situations, and, most particularly, natural science-but only exceptionally by students of literature and hardly ever by historians of Art.

Some observers have called into question whether the Renaissance was a cultural "advance" from the Middle Ages, instead seeing it as a period of pessimism and nostalgia for classical antiquity, while social and economic historians, especially of the longue durée, have instead focused on the continuity between the two eras, which are linked, as Panofsky observed, "by a thousand ties".

The word Renaissance, literally meaning "Rebirth" in French, first appears in English in the 1830s. The word occurs in Jules Michelet's 1855 work, Histoire de France. The wordRenaissance has also been extended to other historical and cultural movements, such as the Carolingian Renaissanceand the Renaissance of the 12th century.
