On the original Clock Tower, there was carousel of Magi following an angel playing a trumpet. Thanks to a type of organ pipe, the trumpet actually played a sound. After the movement renovation was completed in 1757, Ferracina repaired the Magi carousel. He finished in 1759, and at that time, the carousel's schedule was changed. Now, the procession is only shown fifteen days out of the year. When the procession occurs, the Magi and angel pass in front of this statue of the Virgin Mary.
