Identify the importance of guides in the information of the Renaissance and in defeating the concept of a masterpiece

The Renaissance is one of the most interesting and disputed periods of European history. Many scholars see it as a unique time with characteristics all its own. A second group views the Renaissance as the first two to three centuries of a larger era in European history usually called early modern Europe, which began in the late fifteenth century and ended on the eve of the French Revolution (1789) or with the close of the Napoleonic era (1815). Some social historians reject the concept of the Renaissance altogether. Historians also argue over how much the Renaissance differed from the Middle Ages and whether it was the beginning of the modern world, however defined.
