The event of the Scoppio del Carro has its origins in the First Crusade, when Europeans laid siege to the city of Jerusalem in a conflict to claim Palestine for Christianity.
In time, this tradition evolved to something similar to what is seen today; a cart bearing a large candle was rolled through the city to the cathedral, from where the holy fire would be distributed.
Since the event involves a display of great noise and light to ensure a good harvest, farmers from the Florentine countryside still observe the Scoppio del Carro with interest for this traditional reason.
On the morning of Easter Sunday, the 30-foot-tall (9.1 m) antique cart (in use for over 500 years), moves from the Porta al Prato to the Piazza del Duomo.
Hauled by a team of white oxen festooned with garlands of the first flowers and herbs of spring, the cart is escorted by 150 soldiers, musicians, and people in 15th century dress.
