Fearless and in earnest, Arnold came to Rome, and began to preach a great change, a great reform, a great revival, and many heard him and followed him; and it was not in the Pope's power to silence him, nor bring him to any trial. The Pierleoni would support any sedition against Innocent; the Roman people were weary of masters, they listened with delight to Arnold's fierce condemnation of all temporal power, that of the Pope and that of the Emperor alike, and the old words, Republic, Senate, Consul, had not lost their life in the slumber of five hundred years. The Capitol was there, for a Senate house, and there were men in Rome to be citizens and Senators. Revolution was stirring, and Innocent had recourse to the only weapon left him in his weakness. Arnold was preaching as a Christian and a Catholic. The Pope excommunicated him in a general Council. In the days of the Crusades the Major Interdiction was not an empty form of words; to applaud a revolutionary was one thing, to attend the sermons of a man condemned to hell was a graver matter; Arnold's disciples deserted him, his friends no longer dared to protect him under the penalty of eternal damnation, and he went out from Rome a fugitive and an outcast. Wandering from Italy to France, from France to Germany, and at last to Switzerland, he preached his doctrines without fear, though he had upon him the mark of Cain; but if the temporal sovereignty against which he spoke could not directly harm him, the spiritual power pursued him hither and thither, like a sword of flame. A weaker man would have renounced his beliefs, or would have disappeared in a distant obscurity; but Arnold was not made to yield. Goaded by persecution, divinely confident of right, he faced danger and death and came back to Rome. He arrived at a moment when the people were at once elated by the submission of Tivoli, and exasperated against Innocent because he refused to raze that city to the ground. The Pierleoni were ever ready to encourage rebellion. The Romans, at the words Liberty and Republic, rose in a body, rushed to the Capitol, proclaimed the Commonwealth, and forthwith elected a Senate which assumed absolute sovereignty of the city, and renewed the war with Tivoli. The institution then refounded was not wholly abolished until, under the Italian kings, a representative government took its place.
