The Renaissance, from French: Renaissance \"re-birth\", was a cultural movement that spanned the period roughly from the 14th to the 17th century, beginning in Italy in the Late Middle Ages and later spreading to the rest of Europe. Though availability of paper and 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. There is a consensus that the Renaissance began in Florence, Italy, in the 14th century. It is perhaps no accident that the factuality of the Italian 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.
