Ambrogio Lorenzetti (or Ambruogio Laurati) (c. 1290 – 9 June 1348); Italian painter of the Sienese school. Active from approximately 1317 to 1348. He painted The Allegory of Good and Bad Government in the Sala dei Nove (Salon of Nine or Council Room) in Siena's Palazzo Pubblico. His elder brother was the painter Pietro Lorenzetti. Lorenzetti was highly influenced by both Byzantine art and classical art forms, and used these to create a unique and individualistic style of painting. His work was exceptionally original. Individuality at this time was unusual due to the influence of patronage on art. Because paintings were often commissioned, individualism in art was infrequently seen. It is known that Lorenzetti engaged in artistic pursuits that were thought to have their origins during the Renaissance, such as experimenting with perspective and physiognomy, and studying classical antiquity. His body of work clearly shows the innovativeness that subsequent artists chose to emulate. His work, although more naturalistic, shows the influence of Simone Martini. The earliest dated work of the Sienese painter is a Madonna and Child (1319, Museo Diocesano, San Casciano). His presence was documented in Florence up until 1321. He would return there after spending a number of years in Siena. Later he painted The Allegory of Good and Bad Government. The frescoes on the walls of the Room of the Nine (Sala dei Nove) or Room of Peace (Sala della Pace) in Siena's Palazzo Pubblico are one of the masterworks of early Renaissance secular painting.... Annunciation, 1344 Lorenzetti's final piece, contains the first use of clear linear perspective. ...The first evidence of the existence of the hourglass can be found in the fresco, Allegory of Bad Government and Its Effects on Town and Country. Like his brother, he is believed to have died of bubonic plague in 1348.[5] Giorgio Vasari includes a biography of Lorenzetti in his Lives.
