Gianozzo da Salerno was at this time in Bologna.  He held a command under Charles of Durazzo, a descendant of the kings of Naples, who, designing to undertake the conquest of the dominions of Queen Giovanna, retained his captain in that city, with the concurrence of Pope Urban, who was at enmity with the queen.  Many Florentine emigrants were also at Bologna, in close correspondence with him and Charles.  This caused the rulers in Florence to live in continual alarm, and induced them to lend a willing ear to any calumnies against the suspected.  While in this disturbed state of feeling, it was disclosed to the government that Gianozzo da Salerno was about to march to Florence with the emigrants, and that great numbers of those within were to rise in arms, and deliver the city to him.  Upon this information many were accused, the principal of whom were Piero degli Albizzi and Carlo Strozzi:  and after these Cipriano Mangione, Jacopo Sacchetti, Donato Barbadori, Filippo Strozzi, and Giovanni Anselmi, the whole of whom, except Carlo Strozzi who fled, were made prisoners; and the Signory, to prevent any one from taking arms in their favor, appointed Tommaso Strozzi and Benedetto Alberti with a strong armed force, to guard the city.  The arrested citizens were examined, and although nothing was elicited against them sufficient to induce the Capitano to find them guilty, their enemies excited the minds of the populace to such a degree of outrageous and overwhelming fury against them, that they were condemned to death, as it were, by force.  Nor was the greatness of his family, or his former reputation of any service to Piero degli Albizzi, who had once been, of all the citizens, the man most feared and honored.  Some one, either as a friend to render him wise in his prosperity, or an enemy to threaten him with the fickleness of fortune, had upon the occasion of his making a feast for many citizens, sent him a silver bowl full of sweetmeats, among which a large nail was found, and being seen by many present, was taken for a hint to him to fix the wheel of fortune, which, having conveyed him to the top, must if the rotation continued, also bring him to the bottom.  This interpretation was verified, first by his ruin, and afterward by his death.

After this execution the city was full of consternation, for both victors and vanquished were alike in fear; but the worst effects arose from the apprehensions of those possessing the management of affairs; for every accident, however trivial, caused them to commit fresh outrages, either by condemnations, admonitions, or banishment of citizens; to which must be added, as scarcely less pernicious, the frequent new laws and regulations which were made for defense of the government, all of which were put in execution to the injury of those opposed to their faction.  They appointed forty-six persons, who, with the Signory, were to purge the republic of all suspected by the government.  They admonished thirty-nine citizens,
