This portrait is especially done for an exhibition with the theme "Martyrs" that will take place on Nov 2011 in London. Saint Barbara is the patron saint of artillerymen, military engineers, miners and others who work with explosives because of her old legend's association with lightning. She is invoked against thunder and lightning and all accidents arising from explosions of gunpowder. She is the patron of the Italian Navy and is also recognized as the patron saint of U.S. Navy. According to the hagiographies the whip used to torture her miraculously became a peacock feather, so it became part of her iconography.
