1111-1155.] ROME 793 suffers hunger, and, being leagued with the devil, only thirsts for the blood of souls." In 1142 we find Arnold a wanderer in Switzerland, and then, suddenly reappearing in Italy, he arrived in Home. Three different elements entered into his nature and inspired his eloquence an exalted and mystic tempera- ment, a great and candid admiration for classic antiquity added to an equal admiration for republican freedom independent of the church and the empire, and a pro- found conviction, derived from the Vaudois and Paterine doctrines, that the church could only be purified by the renunciation of temporal wealth. Finding Rome already revolutionized in accordance with his own ideas, he immediately began to preach there. His mystic exhorta- tions against the riches of the church had an inflammatory effect, while his classical reminiscences aroused the enthusi- asm of the .Romans, and his suggestion that they should imitate the republican institutions of Upper Italy met the necessities of the time that had created the revolution. He urged the reconstitution of the ancient senate and senatorial order, which indeed was already partially accomplished, and of the ancient equestrian order, and the reconstruction and fortification of the Capitol. His pro- posed senate was a body somewhat resembling the com- munal councils of Upper Italy, his equestrian order a mounted force composed of the lesser nobility, since at Rome, as elsewhere, the lower classes had neither time nor means to form part of it. All his suggestions were accepted ; the citizens laboured strenuously on the fortifica- tion of the Capitol. The pope soon beheld the revolution spread beyond the walls, and several cities of the state proclaimed their independence. The barons of the Cam- pagna profited by the opportunity to act as independent sovereigns. Thus the whole domain of the church was threatened with dissolution. The pope marched towards Rome with his newly gathered army, but hoped to come to terms. The Romans in fact recognized his authority, and he in his turn recognized the republic. The office of patrician was abolished, and seems to have been replaced by that of gonfalonier, and the prefect, answering to the podesta of the other republics, was revived. The senators received investiture from the pope, who returned to Rome at Christmas 1145. The republic now seems to have been fully constituted. The senate was drawn from the lower classes and the petty nobility, and this was the special characteristic of the new revolution. In 1144 there were fifty-six senators, pro- bably four to each of the fourteen regions, but the number often varied. By the few existing documents of the period we notice that the senators were divided into senatores consiliarii and ordinary senators. The former constituted a smaller council, which, like the credenza or lesser council found in other cities, consulted with the head or heads of the republic on the more urgent and secret affairs of the state. And, conjointly with the rest of the senators, it formed the greater council. Thus classic traditions were identified with new republican usages, and the commonwealth of Rome resembled those in other parts of Italy. But, of course, every republic had special local customs of its own. So the Roman senate had judicial as well as political attributes, and there was a curia senatus composed of senators and legal experts. As was easily to be foreseen, the agreement with the pope was of short duration. The revolution could not be checked ; the Romans desired independence, and their spiritual lord fled to France, whence, in 1147, he pro- claimed a new crusade, while the Romans were employed in demolishing Tivoli, banishing its inhabitants, and waging war on other cities. Giordano Pierleone was gonfalonier and head of the republic, and Arnold, sup- ported by the popular favour and the enthusiasm of the lower clergy, was preaching with even greater fervour than before. But the pope now re-entered Italy, pro- claimed Arnold a schismatic, and then advancing to Tusculum assembled an army in order to attack Rome. In this emergency the Romans applied to Conrad III., the first emperor of the house of Hohenstaufen ; and their urgent letters are clearly expressive of Arnold's theories and his medley of ancient and modern, sacred and profane, ideas. "Rome," "so they said, "is the fountain of the empire confided to you by the Almighty, and we seek to restore to Rome the power possessed by her under Constantine and Justinian. For this end we conquered and destroyed the strongholds of the barons who, together with the pope and the Normans, sought to resist us. These are now attacking us on all sides. Haste to Rome, the capital of the world, thus to establish thy imperial sway over the Italian and German lands." After long hesitation the king of the Romans at last replied to these appeals, stating that he would come " to re-establish order, reward the faithful, and punish the rebellious." These words promised ill. In fact Conrad had already arranged terms with the pope ; but his life came to an end on the 15th February 1152. He was succeeded by Frederick I. surnamed Barbarossa, Frederi who took no notice of the numerous letters urging him to I. come and receive the empire from the Roman people, which alone had the right of conferring it. In accordance with his design of subduing all the independent cities, he made an agreement with the pope, in which he vowed to give no truce to the Romans, but subject them to their spiritual lord, whose temporal power should be restored. The pope, on his side, promised to crown him emperor. Thereupon the people again rose to arms, and Arnold broke off all negotiations with Eugenius III. The senate was re- organized, formed of one hundred members, and, according to the old Roman precedent, had two consuls, one for in- ternal and the other for external affairs. Frederick was a daring statesman, a valiant soldier in command of a powerful army, and was no friend of half measures. Accordingly the nobles ventured on reaction. Finally, to increase the gravity of the situation, an English pope, Hadrian IV., was elected (1154-59), who was also a man of strong and resolute temper. In fact, even before being able to take possession of the Lateran, he requested the Romans to banish Arnold, who, with greater eloquence than ever, was directing his thunders against the papacy. These utterances increased the wrath of Hadrian, who, encouraged by the knowledge that Frederick and his host were already in Italy, at last launched an interdict against Rome. It was the first time that a pope had ventured to curse the Eternal City. The interdict put a summary stop to the religious life of the inhabitants. Men's minds were seized with a sudden terror, and a fierce tumult broke out. Thereupon the senators, whose opposition to the pope was less courageous than that of the fallen magnates, prostrated themselves at his feet and implored pardon. But Hadrian demanded the expulsion of Arnold before consenting to raise the interdict. Arnold was therefore obliged to leave Rome. After having for nine years preached successfully in favour of liberty, after having been the moving spirit of the new revolution, the new con- stitution, he was now abandoned by all, and forced to wander from castle to castle, in the hope of reaching some independent city capable of shielding him from the fierce enmity of the pope. Meanwhile Frederick I. had achieved his first victories in Lombardy, and, leaving ruined cities and bloodshed in his track, was rapidly advancing towards central Italy. The pope sent three cardinals to him, with a request for the capture and consignment of Arnold, who XX. 100
