Saint Laurentius (San Lorenzo), to whom this church in Saro is dedicated, is one of the early Christian martyrs from a time when Christianity was still forbidden. He was Archdeacon of the Pope and asked by the pagan emperor to hand over the treasure of the Church. Laurentius asked for three days' time, in the meantime he distributed the church property among the poor inhabitants of Rome and, after the agreed time, came with the poor to the emperor in order to present them to him as the church's treasure. He was then martyred to death, legend has it that he was alive on a grate - this attribute can be seen in many depictions of Saint Laurentius - roasted over coals. He is said to have been in good spirits and told his executioner on the one hand he was ready, whether he didn't want to turn him over.
The commemoration of San Lorenzo in the calendar of saints is August 10th.
