Like the murder of Pierre de Castelnau in Languedoc, this crime turned the scale. Its immediate effect was to cause a revulsion of popular feeling, which hitherto had been markedly hostile to the Inquisition. The news of the assassination spread through the city with marvellous rapidity and before dawn the streets were filled with excited crowds shouting "Burn the Conversos who have slain the inquisitor!" There was danger, in the exaltation of feeling, not only that the Conversos would be massacred but that the Judería and Morería would be sacked. By daylight the archbishop, Alfonso de Aragon, mounted his horse and traversed the streets, calming the mob with promises of speedy justice. A meeting was at once called of all the principal persons in the city, which resolved itself into a national assembly and empowered all ecclesiastical and secular officials to proceed against every one concerned with the utmost vigor and without observing the customs and fueros of the kingdom.[656] For some days the Conversos continued to flatter themselves that with money they would disarm Ferdinand's wrath; they had, they said, the whole court with them and the sympathies of all the magnates of the land,[657] but they miscalculated his shrewd resolve to profit to the utmost by their blunder and the consequent weakness of their friends. The royal anger, indeed, was much dreaded and the Diputados, a few days later, wrote to the king reporting what had been done; the criminals had already scattered in flight; the city had offered a reward of five hundred ducats; the judges had written to foreign lands to invoke aid in intercepting the fugitives and both city and kingdom would willingly undergo all labor and expense necessary to avenge the crime. A proclamation was also issued excommunicating all having knowledge of the conspiracy who should not within a given time come forward and reveal what they knew.[658] It was probably in consequence of the murder that Ferdinand and Isabella succeeded in obtaining, from Innocent VIII, papal letters of April 3, 1487, ordering all princes and rulers and magistrates to seize and deliver to the Inquisition of Spain all fugitives who should be designated to them, thus extending its arms everywhere throughout Christendom and practically outlawing all refugees; no proof was to be required, simple requisition sufficed, the surrender was to be made within thirty days and safe-conduct assured to the frontier, under pain of excommunication and the penalties for fautorship of heresy. Fortunately for humanity this atrocious attempt to establish a new international law by papal absolutism was practically ignored.[659] [Sidenote: _THE INQUISITION AT WORK_]
