April 7th was the day fixed for the _Sperimento del Fuoco_. In the Piazza de’ Signori a huge pile of wood, plentifully reinforced with gunpowder, sulphur, oil, and spirits, was built with a gangway through which the champions were to pass; it was to be lighted at one end, and after they entered fire was to be set at the other to preclude retreat. All Florence assembled to witness the spectacle, and patiently endured the peltings of a terrible storm. The day was spent, however, in wrangling over questions skilfully raised by the Franciscans, the chief one being whether Fra Domenico should carry in his hand a consecrated host. It had been revealed to one of his brethren that this was indispensable, and Savonarola adhered to it firmly. When evening came the Signoria announced that the ordeal was abandoned. The crowd was enraged at the loss of the promised exhibition; the Dominicans had so confidently promised a miracle that the drawn battle was universally regarded as their defeat, an armed guard was required to protect their return to their convent, and Savonarola’s power over the Florentine populace was gone. His enemies lost no time in pushing their advantage. The next evening the mob assailed San Marco; he was seized and conveyed to prison, and after prolonged and repeated tortures he was hanged and burnt on May 23d.[983] It will be observed that the ordeal of fire was principally affected by ecclesiastics in church affairs, perhaps because it was of a nature to produce a powerful impression on the spectators, while at the same time it could no doubt in many instances be so managed as to secure the desired results by those who controlled the details. In like manner, it was occasionally employed on inanimate matter to decide points of faith or polity. Thus, in the question which excited great commotion in Spain, in 1077, as to the substitution of the Roman for the Gothic or Mozarabic rite, after a judicial combat had been fought and determined in favor of the national ritual, the partisans of the Roman offices continued to urge their cause, and the ordeal of fire was appealed to. A missal of each kind was committed to the flames, and, to the great joy of all patriotic Castilians, the Gothic offices were unconsumed.[984] More satisfactory to the orthodox was the result of a similar ordeal during the efforts of St. Dominic to convert the Albigenses. In a dispute with some heretics he wrote out his argument on the points of faith, and gave it to them for examination and reply. That night, as they were seated around the hearth, the paper was produced and read, when one of them proposed that it should be cast into the flames, when, if it remained unconsumed, they would see that its contents were true. This was promptly done, when the saintly document was unharmed. One, more obstinate than the rest, asked for a second and then for a third trial, with the same result. The perverse heretics, however, closed their hearts against the truth, and bound
