The Renaissance (UK /rɨˈneɪsəns/, US /ˈrɛnɨsɑːns/, French pronunciation: [ʁənɛsɑ̃ːs], French: Renaissance, Original Italian: Rinascimento, from rinascere "to be reborn") 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. 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 the development of the conventions of diplomacy, and in science an increased reliance on observation. Historians often argue this intellectual transformation was a bridge between the Middle Ages and the Modern era. 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".
