Paolo Uccello, about 1397 - 1475, The Battle of San Romano about 1438-40 © The National Gallery, London
This brilliantly structured and colourful painting depicts part of the battle of San Romano that was fought between Florence and Siena in 1432. The central figure is Niccolò da Mauruzi da Tolentino on his white charger, the leader of the victorious Florentine forces, who is identifiable by the motif of 'Knot of Solomon' on his banner.
This panel is one of a set of three of the same battle, the other two are in the Louvre, Paris, and the Uffizi, Florence. This painting and its two companion panels were commissioned by the Bartolini Salimbeni family in Florence sometime between 1435 and 1460: only the Uffizi panel is signed. Lorenzo de' Medici so coveted them that he had them forcibly removed to the Medici palace.
The wonderful thing about printed paintings on pocket squares is that they can produce a number of different effects depending on how they are folded and creates a great topic for conversation once pulled out of the breast pocket.
