Worse invectives even, no less forcible than those of later reformers, he hurled against Rome. "In the flames and torments of hell is thy place!... Thou hast the appearance of an innocent lamb, but inwardly thou art a raging wolf, a crowned snake, begotten by a viper, the friend of the devil!" Even the good-natured German minnesinger, Walter von der Vogelweide, found bitter words against Rome: "They point our way to God and go to hell themselves." Bernard of Clairvaux, the supporter of the Church, sharply criticised the abuses of pope and clergy in his book, _De Consideratione_: "The property of the poor is sown before the door of the rich, the gold glitters in the gutter, the people come hurrying up from all sides; but not to the neediest is it given, but to the strongest and to him who is first on the spot." He accused the pope of extravagance and luxury: "Was Peter clothed in robes of silk, covered with gold and precious stones? Was he carried in a litter surrounded by soldiers and vassals?" And he uttered a word which to this day is a historical truth: "In all thy splendour thou art the successor of Constantine rather than the successor of Peter." Dissatisfaction with the life of the clergy and the tyranny of Rome was the more external reason which, although it vexed even those who were indifferent to religion, did not question the sacred tradition; the other reason was more a matter of principle; it was rooted in the desire for a religious revival and openly attacked perverted truths. The dreaded, hated, and cruelly persecuted heretics were fearless men, sturdily fighting for their convictions. The fundamental ideal of these reformers was the suppression of the outward pomp of the Church and the return to the simplicity of the gospels. Their fates varied. The gentle St. Francis of Assisi was canonised; the illumined Eckhart, on the other hand, was tortured; most of them, like the ardent Arnold of Brescia, were burnt at the stake. This conduct of the hierarchy towards the truly religious men is easily explained. The Church was faced by a problem; on the one hand, the genuine and profound piety of these men was unmistakable, but on the other, the contrast of their teaching with Church tradition was too obvious, and by many of them too strongly emphasised to be silently ignored.
