If you walk around the Duomo Cathedral in Florence, you will hit by a powerful wind. Florentine people call this wind "Il Rifrullo del Diavolo."
The legend tells that the Devil was chasing a priest, through the city, to take his soul. When they arrived in Piazza Duomo, the dying wish of clergyman was to pray for the last time. He went inside the Cathedral while Satan was waiting him outside. The clever priest exploited this occasion to escape from a secondary door.
The Devil began to puff for the boredom and, when he learned the trick, the puff became a vortex. Thenceforth, when someone pass through the Cathedral, can still feel the fury of the cheated Devil.
