Even St. Peter Damiani, generally unmeasured in his invectives against simony, wrote to moderate the frantic zeal of the Vallombrosian monks, which he denounced as unreasonable, intemperate, unjust.
But the refusal of the Pope to gratify their resentment did not quell the vehemence of the monks and the faction adverse to the bishop. The city was in a condition of chronic insubordination and occasional rioting. Godfrey Duke of Tuscany was obliged to interfere; and the monks were driven from their monastery of St. Salvi, and compelled to retire to that of St. Settimo outside of the gates.
Shortly after, Pope Alexander visited Florence. The monks piled up a couple of bonfires, and offered to pass between them in proof of the truth of their allegation. He refused to permit the ordeal, and withdrew, leaving the bishop unconvicted, and therefore unrebuked.
The clergy of Florence now determined to demand of the bishop that he should either go through the ordeal himself, or suffer the monks to do so. As they went to the palace, the people hooted them: "Go, ye heretics, to a heretic! You who have driven Christ out of the city! You who adore Simon Magus as your God!"
The bishop sullenly refused; he would neither establish his innocence in the fire, nor suffer the monks to convict him by the ordeal.
The Podesta of Florence then, with a high hand, drove from the town the clergy who had joined the monastic faction. They went forth on the first Saturday in Lent, 1067, amidst a sympathising crowd, composed mostly of women,[35] who tore off their veils, and with hair scattered wildly over their faces, threw themselves down in the road before the confessors, crying, "Alas! alas! O Christ, Thou art expelled this city, and how dost Thou leave us desolate? Thou art not tolerated here, and how can we live without Thee? Thou canst not dwell with Simon Magus. O holy Peter, didst thou once overcome Simon? and now dost thou permit him to have the mastery? We deemed him bound and writhing in infernal flames, and lo! he is loose, and risen again to thy dishonour."
And the men said to one another, "Let us set fire to this accursed city, which hates Christ."[36]
The secular clergy were in dismay; denounced, deserted, threatened by the people, they sang no psalms, offered no masses. Unable to endure their position, they again visited the bishop, and entreated him to sanction the ordeal of fire. He refused, and requested the priests not to countenance such an unauthorised venture, should it be made. But the whole town was bent on seeing this ordeal tried, and on the Wednesday following, the populace poured to the monastery of St. Settimo. Two piles of sticks were heaped near the monastery gate, measuring ten feet long by five wide, and four and a half feet high. Between them lay a path the length of an arm in width.
Litanies were chanted whilst the piles were reared, and then the monks proceeded to elect one who was to undergo the fire. The lot fell on a priest named Peter, and St. John Gualberto ordered him at once to the altar to say mass. All assisted with great devotion, the people crying with excitement. At the Agnus Dei four monks, one with the crucifix, another with holy water, the third with twelve lighted tapers, the fourth with a full censer, proceeded to the pyres, and set them both on fire.
