Pietro Lorenzetti

Pietro Lorenzetti (Italian: [ˈpjɛːtro lorenˈtsetti]; c. 1280 – 1348) or Pietro Laurati was an Italian painter, active between c. 1306 and 1345. Together with his younger brother Ambrogio, he introduced naturalism into Sienese art. In their artistry and experiments with three-dimensional and spatial arrangements, the brothers foreshadowed the art of the Renaissance.
