The term Renaissance was first used to describe a specific period in history by Balzac in a novel in 1829. It subsequently gained currency in intellectual circles. In 1855, it was used by Jules Michelet for the title of his book La Renaissance, 1855, and in 1860 is was employed definitively by Jacob Burckhardt in his The Civilization of the Renaissance in Italy. It was also used by Ruskin, Stones of Venice in 1851, and by Trollope, Summer in Brittany, in 1840.
