On June 24, Hildebrand, now Gregory VII., wrote to the Margravine Beatrice to abstain from all relations with the excommunicated bishops of Lombardy; on June 28, to William, Bishop of Pavia, to oppose the usurper, the excommunicate Godfrey of Milan; on July 1, to all the faithful of Lombardy to refrain from that false bishop, who lay under the apostolic ban. From Capua, on September 27, he wrote to Herlembald, exhorting him to fight valiantly, and hold out Milan against the usurper Godfrey. Again, on October 9, to Herlembald, bidding him be of good courage; he hoped to detach the young Emperor from the party of Godfrey, and bade him receive amicably those who, with true sentiments of contrition, came over to the Patarine, that is, the Papal side.

On March 10, 1074, Gregory held one of the most important synods, not of his reign only, but ever held by any Pope. The acts of this assembly have been lost or suppressed, but its most important decisions were summed up in a letter from Gregory to the Bishop of Constance. This letter has not been printed in the Registrum; but fortunately it has been preserved by two contemporary writers, Paul of Bernried, and Bernold of Constance, the latter of whom has supplied a detailed apology for the law of celibacy promulgated in that synod. Gregory absolutely forbade all priests sullied with the crimen fornicationis, which embraced legitimate marriage, either to say a mass or to serve at one; and the people were strictly enjoined to shun their churches and their sacraments; and when the bishops were remiss, he exhorted them themselves to enforce the pontifical sentence.[41]

The results shall be described in the words of a contemporary historian, Sigebert of Gemblours. "Many," says he, "seeing in this prohibition to hear a mass said by a married priest a manifest contradiction to the doctrine of the Fathers, who believed that the efficacy of sacrament, such as baptism, chrism, and the Body and Blood of Christ, is independent of the dignity of the minister, thence resulted a grievous scandal; never, perhaps, even in the time of the great heresies, was the Church divided by a greater schism. Some did not abandon their simony, others disguised their avarice under a more acceptable name; what they boasted they had given gratuitously, they in reality sold; very few preserved continence. Some through greed of lucre, or sentiments of pride, simulated chastity, but many added false oaths and numerous adulteries to their debaucheries. The laity seized the opportunity to rise against the clerical order, and to excuse themselves for disobedience to the Church. They profaned the holy mysteries, administering baptism themselves, and using the wax out of their ears as chrism. They refused on their death-beds to receive the viaticum from the married priests; they would not even be buried by them. Some went so far as to trample under foot the Host, and pour out the precious Blood consecrated by married priests."[42]

The affairs of the church of Milan continued in the same unsatisfactory condition. The contest between the Patarines and their adversaries had taken greater dimensions. The question which divided them was now less that of the marriage of the clergy than which of the rival archbishops was to be acknowledged. Godfrey was supported by the Emperor, Otto by the Pope. The parties were about even; neither Godfrey nor Otto could maintain himself in Milan; the former fortified himself in the castle of Brebbio, the latter resided at Rome. Henry IV., in spite of all the admonitions of the Pope, persisted in supporting the cause of Godfrey. Milan was thus without a pastor. The suffragan bishops wished to execute their episcopal functions in the city, and to consecrate the holy oils for the benediction of the fonts at Whitsuntide. Herlembald, when one of the bishops had sent chrism into the city for the purpose, poured it out on the ground and stamped on it, because it had been consecrated by an excommunicated prelate.

In March, 1075, another conflagration broke out in the city, and raged with even greater violence than the fire of 1071. Herlembald had again poured forth the oils, as he had the year before; and had ordered Leutprand, a priest, as Easter came, to proceed to the consecration of chrism. This innovation roused the alarm of the Milanese; the subsequent conflagration convinced them that it was abhorrent to heaven. All the adversaries of the Patarines assembled outside the city, and swore to preserve intact the privileges of St. Ambrose, and to receive only the bishop nominated or approved by the King. Then, entering the city, they fell unexpectedly on the Patarines. Leutprand was taken and mutilated, his ears and nose were cut off. The standard of St. Peter was draggled in the dust, and Herlembald fell with it, cut down by a noble, Arnold de Rauda. Every insult was heaped on the body of the "Defender of the Church," and the sacred banner was trampled under foot.

Messengers were sent to Henry IV. to announce the triumph, and to ask him to appoint a new Archbishop of Milan. Henry was so rejoiced at the victory, that he abandoned Godfrey, and promised the Milanese a worthy prelate. His choice fell on Tebald, a Milanese sub-deacon in his Court.

Pope Urban II. canonised Herlembald. Ariald seems never to have been formally enrolled among the saints, but he received honours as a saint at Milan, and has been admitted into several Italian Martyrologies, and into the collection of the Bollandists. Baronius wisely expunged Herlembald and Ariald from the Roman Martyrology; nevertheless, the disgraceful fact remains, that the ruffian Herlembald has been canonised by Papal bull.

The seeds of fresh discord remained. Leutprand, or Liprand, the priest, was curate of the Church of St. Paul;[43] having suffered mutilation in the riot, he was regarded in the light of a Patarine confessor. But no outbreak took place till the death of Anselm IV., Archbishop of Milan (September 30, 1101), at Constantinople, where he was on his way with the Crusaders to the Holy Land. His vicar, the Greek, Peter Chrysolaus, Bishop of Savonia, whom the Lombards called Grossulani, perhaps because of the coarse habit he wore (more probably as a corruption for Chrysolaus), had been left in charge of the see of Milan. On the news of the death of the Archbishop reaching that city, the Primicerius convoked the electors to choose a successor. The vote fell on Landulf, Ordinary of Milan; but he was not yet returned from Jerusalem, whither he had gone as a crusader. Grossulani declared the election informal. Thereupon the Abbot of St. Dionysius, at the head of a large party of the electors, chose Peter Grossulani. There is no evidence of his having used bribery in any form; but he may have acted unjustly in cancelling the election of Landulf. It is, however, fair to observe that Landulf, on his return, supported Grossulani; consequently, it is probable that the latter acted strictly in accordance with law and precedent.

But the election displeased Liprand and the remains of the Patarines. They appealed to Rome, but Grossulani, supported by the Countess Matilda and St. Bernard, abbot of Vallombrosa, overcame their objections. Pope Paschal II. ratified the election, and sent the pall to the Archbishop. Ardericus de Carinate had been sent to Rome on behalf of Grossulani. The people came out of the gates, on his approach, to learn the result. Ardericus, hanging the pall across his umbrella (protensi virga), waved it over his head, shouting, "Ecco la stola! Ecco la stola!" (Here is the pall!) and led the way into the cathedral, whither Grossulani also hastened, and ascending the pulpit in his pontifical habit, placed the coveted insignia about his neck.
