The Private Life Of A Masterpiece
Is a set of three paintings by the Florentine painter Paolo Uccello depicting events that took place at the battle of San Romano in 1432. The paintings are in tempera on wooden panels, being each over 3 metres long. They were commissioned by the Bartolini Salimbeni family. They are significant as revealing the development of linear perspective in Early Italian Renaissance painting, and are unusual as a major secular commission.
The painting were much admired in the 15th century. They passed into the hands of the Medici family to whom they belonged for about 300 years. They are now divided between three collections, the National Gallery, London, the Galleria degli Uffizi and the Musée du Louvre, Paris.
