Around this square is a niche, with a stone text plaque underneath. In this plaque you’ll find a name. This name will be your guide trough finding my lastname.
On the plaque is a text written:
Chi recita un credo innanzi questa cappella guandagna 100 giorni dindulgenza concessa da s eccarcivescovo di Palermo (NAME)
Who recites a creed before this chapel gains 100 days of indulgence granted by the bishop of Palermo (NAME)
The name of the bishop is the key of the cryptography. In a way that the number one refers to the first letter, number two to the second, and so on.
Fill in the name of the bishop as a password to the next step. Use his first and last name with a space in between.
