Amid the procession of doges and captains that fills the walls of San Zanipolo is a gilded wooden knight missing his right arm: the stump can be seen clearly from below. It is not damage: it is a faithful portrait. That man was Pompeo Giustiniani, called ’Braccio di ferro’ (Iron Arm), and he had really lost the arm. Born in Ajaccio in 1569 to a Genoese family, Giustiniani became a soldier of fortune very young, in Spain’s pay in Flanders.
