"Pietro Lorenzetti (Italian pronunciation: [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." - (en.wikipedia.org 09.06.2021)
