It was reserved for the only Englishman who ever attained to the papacy to visit Rome with the punishment she had so often inflicted upon others. Nicolas Breakspear--Adrian IV.--put the Eternal City under interdict, thereby ending the republic which the partisans of Arnold of Brescia had set up. But in this he was greatly aided by a change of sentiment in many of the inhabitants of Rome, who had found to their cost that it was more profitable for their city to be the centre of Christianity than the seat of a phantom republic. [Sidenote: Murder of Arnold of Brescia.] As an equivalent for his coronation by Adrian, Frederick Barbarossa agreed to surrender to the Church Arnold of Brescia. With indecent haste, the moment she had obtained possession of her arch-enemy she put him to death--not delivering him over to the secular arm, as the custom had been, but murdering him with her own hand. Seven centuries have elapsed, and the blood of Arnold is still crying from the ground for retribution. Notwithstanding a new--the third--crusade, things went from bad to worse in the Holy Land. Saladin had retaken Jerusalem, A.D. 1187. Barbarossa was drowned in a river in Pisidia. Richard of England was treacherously imprisoned; nor did the pope interfere for this brave soldier of the Cross. [Sidenote: Birth of Frederick II.] In the meantime, the Emperors of Germany had acquired Sicily by marriage--an incident destined to be of no little importance in the history of Europe; for, on the death of the Emperor Henry VI. at Messina, his son Frederick, an infant not two years old, was left to be brought up in that island. What the consequences were we shall soon see. [Sidenote: Review of the preceding events.] If we review the events related in this chapter, we find that the idolatry and immorality into which Rome had fallen had become connected with material interests sufficiently powerful to ensure their perpetuation; that converted Germany insisted on a reform, and therefore made a moral attack on the Italian system, attempting to carry it into effect by civil force. This attack was, properly speaking, purely moral, the intellectual element accompanying it being derived from Western or Arabian influences, as will be shown in the next chapter; and, in its resistance to this, the papacy was not only successful, but actually was able to retaliate, overthrowing the Emperors of Germany, and being even on the point of establishing a European autocracy, with the pope at its head. It was in these events that the Reformation began, though circumstances intervened to postpone its completion to the era of Luther. Henceforth we see more and more plainly the attitude in which the papacy, through its material interests, was compelled to stand, as resisting all intellectual advancement. Our subject has therefore here to be left unfinished until we shall have described the Mohammedan influences making pressures on the West and the East. CHAPTER II.
