The cult of the Madonna dell'Arco dates back to the 1400s, when a young believer, after losing a game of pallamaglio, threw a ball in anger at a portrait of the Madonna under a Roman arch. The Madonna began to bleed. The crowd wanted to punish the boy for his wicked deed. The Count of Sarno decided to have him hanged from a tree. A few hours later, the tree withered. This is the myth that has always accompanied the oldest Marian cult in Campania (Italy).
