The altar owes its origin to Father Francesco Sciocchetti. He elevated San Biago to the patron Saint of Funai and Canapini. He was already the protector of carders because martyred with combs similar to those used to card wool or comb hemp and invoked for throat diseases. The choice of the Saint is certainly due to the fact that the usurping work of Funaio and Canapino exposed the respiratory system to possible and serious disabling diseases.
There are two bas-reliefs at the bottom left and right of the altar dedicated to Funai and Canapini workers. They were sculpted by Father Luigi Sciocchetti: on one side there is the wheel (symbol of Funai) and on the other one there is a comb to card hemp.
The statue of the Saint with the child is placed on a niche. On February 3, 1911 Father Francesco Sciocchetti began the tradition of Mass and breakfast for Funai and their families.
