"To some it might seem, considering the interests of religion alone, desirable to omit all biographical reference to the popes; but this cannot be done with justice to the subject. The essential principle of the papacy, that the Roman pontiff is the vicar of Christ upon earth, necessarily obtrudes his personal relations upon us. How shall we understand his faith unless we see it illustrated in his life? Indeed, the unhappy character of those relations was the inciting cause of the movements in Germany, France, and England, ending in the extinction of the papacy as an actual political power, movements to be understood only through a sufficient knowledge of the private lives and opinions of the popes. It is well, as far as possible, to abstain from burdening systems with the imperfections of individuals. In this case they are inseparably interwoven. The signal peculiarity of the papacy is that, though its history may be imposing, its biography is infamous. I shall, however, forbear to speak of it in this latter respect more than the occasion seems necessarily to require; shall pass in silence some of those cases which would profoundly shock my religious reader, and therefore restrict myself to the ages between the middle of the eighth and the middle of the eleventh centuries, excusing myself to the impartial critic by the apology that these were the ages with which I have been chiefly concerned in this chapter. "On the death of Pope Paul I, who had attained the pontificate A. D. 757, the Duke of Nepi compelled some bishops to consecrate Constantine, one of his brothers, as pope; but more legitimate electors subsequently, A. D. 768, choosing Stephen IV, the usurper and his adherents were severely punished; the eyes of Constantine were put out; the tongue of the Bishop Theodoras was amputated, and he was left in a dungeon to expire in the agonies of thirst. The nephews of Pope Adrian seized his successor, Pope Leo III, A. D. 79, in the street, and, forcing him into a neighboring church, attempted to put out his eyes and cut out his tongue; at a later period, this pontiff, trying to suppress a conspiracy to depose him, Rome became the scene of rebellion, murder and conflagration. His successor, Stephen V, A. D. 816, was ignominiously driven from the city: his successor, Paschal I, was accused of blinding and murdering two ecclesiastics in the Lateran Palace; it was necessary that imperial commissioners should investigate the matter, but the pope died, after having exculpated himself by oath before thirty bishops. John VIII, A. D. 872, unable to resist the Mohammedans, was compelled to pay them tribute; the Bishop of Naples, maintaining a secret alliance with them, received his share of the plunder they collected. Him John excommunicated, nor would he give him absolution unless he would betray the chief Mohammedans and assassinate others himself. There was an ecclesiastical conspiracy to
