The highlight at the entrance is the huge 12th-century Romanesque baptismal font (the "Fonte Lustrale"). It is composed of a bowl, covered with a "tempietto", resting on pillars, inside a circular basin. It is the craftmanship of master Roberto (his signature is on the basin) and two unknown masters. The basin is decorated with "The Story of Moses" by a Lombard sculptor. Master Roberto did the last two panels "The Good Shepherd" and the "Six Prophets". The tempietto was sculpted by a Tuscan master, representing the months of the year and the apostles.
