Lorenzetti, Ambrogio

▪ Italian painter

born c. 1285, Siena, Republic of Siena

died c. 1348

 younger brother of Pietro Lorenzetti (Lorenzetti, Pietro), who ranks in importance with the greatest of the Italian Sienese painters, Duccio and Simone Martini. Only six documented works of Ambrogio, apparently covering a period of merely 13 years, have survived. They include four scenes from the legend of St. Nicholas of Bari in the Uffizi, Florence, which are parts of an altarpiece painted about 1332 in Florence; the “Good and Bad Government” wall decorations of 1337–39 in the Sala della Pace in the Palazzo Pubblico, Siena, and the signed and dated panels of the “Presentation of Christ in the Temple” (1342) in the Uffizi and of the “Annunciation” (1344) in the Pinacoteca Nazionale, Siena.

      It is not known who Ambrogio's teacher was, but his early works indicate that he early received his main inspiration from the art of Duccio, his brother Pietro, and Giotto. Already his representations reveal a realistic individualism and an intense preoccupation with significant composition and form. These characteristics are most evident in the “Allegories” in the Palazzo Pubblico, the most important Sienese fresco decoration. In it Ambrogio is seen as an acute observer, an empirical explorer of linear and aerial perspective, a student of classical works of art, and a political and moral philosopher. His desire to depict spatial depth convincingly led him to an increasingly accurate rendering of space in his paintings and almost to one-point perspective in his last work, the “ Annunciation.” With his profound interest in perspective and in classical antiquity, Ambrogio anticipated the Renaissance. The art of the Lorenzettis was widely imitated in Siena during the third quarter of the 14th century, and many works by close followers are still commonly attributed to one or the other brother.
