Florence, the explosion of the wagon

Two oxen pull the chariot in the shape of a 3-storey tower up to the Piazza del Duomo, here the Archbishop lights up a dove-shaped rocket from the altar, the “colombina” through a rope runs along the entire nave of the cathedral until it reaches the wagon on the outside making all the fireworks burst inside it, so the “colombina” continues its journey by going back through the nave.
