Century Dictionary and Cyclopedia

1. n. A disciple of Arnold of Brescia, who in Italy in the twelfth century preached against the ambition and luxury of ecclesiastics, not sparing the pope himself. He maintained the subordination of the ecclesiastical to the temporal power, and proclaimed the necessity of both a civil and an ecclesiastical revolution. In 1146 he put himself at the head of a temporarily successful insurrection against the temporal power of the pope. He was put to death in 1155.
