was sent back to his provincial with orders to subject him to a punishment that would prevent a repetition of the sacrilege. Yet successive popes encouraged the cult of San Piero until Sixtus V., in 1586, designated him as the second head of the Inquisition after St. Dominic, and as its first martyr, and in 1588 granted plenary indulgence to all who should visit for devotion the Dominican churches on the days of St. Dominic, Peter Martyr, and Catharine of Siena. In the seventeenth century an enthusiastic Spaniard declared that he was crowned with three crowns, “_como Emperador de Martyres_.” In 1373, Gregory XI. granted permission to erect a small oratory on the spot of the murder, which grew to be a magnificent church with a splendid convent, through the offerings of the innumerable pilgrims who flocked thither. The authenticity of the martyr’s sanctity was proved when, in 1340, eighty-seven years after death, the body was translated to a tomb of marvellous workmanship, and was found in a perfect state of preservation; and when the sepulchre was opened in 1736 it was still found uncorrupted, with wounds corresponding exactly to those described in the annals.[239] The enthusiasm excited by the career of San Piero was turned to practical account by the organization in most of the Italian cities of _Crocesegnati_, composed of the principal cavaliers, who swore to defend and assist the inquisitors at peril of their lives, and to devote person and property to the extermination of heretics, for which service they received plenary remission of all their sins. These associations were wont to assemble on the feast of San Piero in the Dominican churches, which were the seats of the Inquisition, and hold aloft their drawn swords during the reading of the Gospel, in testimony of their readiness to crush heresy with force. They continued to exist until the last century, and Frà Pier-Tommaso Campana, who was inquisitor at Crema, relates with pride how, in 1738, he presided over such a ceremony in Milan. The Crocesegnati, moreover, furnished material support to the inquisitors, supplying them when necessary with both men and money for the performance of their functions. In fact, they were subject to excommunication if they refused to give money when called upon by the inquisitor. It can readily be conceived how greatly the effectiveness of the Inquisition was increased by such an organization.[240]
