A little lower down the hill is the small church dedicated to S. Costanzo. For some obscure reason this saint, who is purely local, has become the patron saint of lovers, and on his feast day all the lovers of the neighbourhood assemble at the shrine. If the eye of S. Costanzo blinks at the young man or the girl who kneel before his image, they feel a happy certainty that the course of their affection will run smooth, and that the year will end in happy union. S. Costanzo was converted to the Christian faith by S. Ercolano I., whom he succeeded as bishop of Perugia, and Ciatti gives us a long list of his virtues and his miracles. The blind of the city received their sight from him, we hear, and the lame were made to walk. But all his miracles and his conversions made him an object of hatred to the pagans, and one day he was seized together with his followers, and thrown into prison. They were then put into scalding baths, "but," says Ciatti, "the Holy Ghost, who filled their souls with fire, tempered the external heat, and they sang hymns to signify their great tranquillity." Their only discomfort lay in the darkness all around them, but soon "a wonderful brightness appeared unto them from heaven which comforted them exceedingly." Then the pagans continued their tortures and forced the Saint to walk on burning embers, but as these did him no harm he was stripped and covered with red hot coals; and all the time he went on singing much to the annoyance of his tormentors. Finally he and his followers made their escape and fled to Spello, where fresh conversions, followed by fresh tortures, are recounted. At last, in 154 A.D., he met his death at Spoleto. His body was taken back to Perugia by a certain Serviano da Foligno, who found it "surrounded by a choir of rejoicing angels, and in a shroud of heavenly light. The holy burden was too heavy for Serviano to carry alone, and he called on two men who were passing by to help him. At first they refused and scoffed at the miracles he related, whereupon they were both struck blind, and trembling, they prayed for mercy to the God of the Christians. On touching the body of the Saint they received their sight, whereat they gladly helped to carry it into Perugia. They entered by Porta S. Pietro, and were met by many of the faithful." The body of S. Costanzo is buried in the little church outside the Porta S. Pietro, rebuilt by the present Pope, and the beautiful byzantine doorway seems a fit entrance to the tomb of this suffering and much tormented martyr of Perugia. CHAPTER VII _Piazza del Papa, S.
