We heard that the Duke of Milan(1) had been stabbed and killed by one of his citizens called Giovanni Andrea,(2) who was moved to commit the crime by certain unjust acts of the duke. He was put to death by the populace, out of zeal for the common good. There were several conspirators; and the first who reached the duke was this Giovanni Andrea, who feigned to offer him a letter with one hand whilst he stabbed him with the other. It happened as with Scevola the Roman, when they took life for life. Such men are rarely found. And I believe that they carry out their crimes by divine permission. This was on the day of Santo Stefano, in church, during the mass. And when they tried to flee, they could not, because the crowd of people, and mostly the women who hindered them by spreading out their gowns(3) in such a way that the barons of the duke, and chiefly a certain Ghezzo who stood next to him, caught and slew the said Giovanni Andrea. And three others were taken and hung. Some people said that these three who were caught were quartered by four horses.

A certain hermit came here to preach and threatened many ills. He had been at Volterra, serving at a leper hospital. He was a lad of twenty-four, barefoot, with a wallet on his back; and he declared that St. John and the Angel Raphael had appeared to him. And one morning he went up on to the ringhierra of the Signori to preach, but the "Eight" sent him away. And each day some incident happened.

And at this time, a son of the Duke of Milan,(1) who was confined within certain boundaries in the territory of Pisa, fled from there, and went to Genoa to the Signor Roberto,(2) and joined him.

(1) This was Ludovico Sforza, called Il Moro, uncle to the reigning duke, and at that moment exiled.

(2) Roberto da Sanseverino.
