Tradition holds that they were acquired in 1101 by Pazzino dei Pazzi, who was among the first Christians to scale the walls and lead to the capture of Jerusalem during the First Crusade.

The flints are linked to the ceremony of Lo Scoppio del Carro and the lighting of fireworks from the Portafuoco after a celebratory mass.
