We heard that the Pisans had risen and taken possession of the city; and pulling down a certain marble marzocco, had dragged it all over Pisa, and then thrown it into the Arno, crying, "Liberta!" We also heard that Piero and his brothers were at Bologna; and such a crowd of French and Swiss were coming into Florence, that there was great confusion and alarm and suspicion amongst all classes. You may think what it was to have all this crowd in our houses, and everything left as usual, with the women about, and to have to serve them with whatever they needed, at the greatest inconvenience.
Entry from "A Florentine Diary" by Luca Landucci:
There was much whispering amongst the people, who said suspiciously: "This king doesn't know what he wishes; he has not yet signed the agreement." And many declared that some of his counsellors were endeavouring to hinder it, as there was a certain Signore di Bre,(1) lodging in the house of Giovanni Tornabuoni, who said that he had promised some people to get Piero reinstated, and to persuade the king to ask for this, but perhaps it was not true. This was, as I say, the opinion of many of the citizens, and therefore they were in great dread; still more so when it was said that the king was going this morning to dine in the Palagio with the Signori and that he had caused all the armed men to be removed from the Palagio, and he was going there with many armed men, so that everyone suspected him of evil designs. There was no one who did not take pains this morning to fill his house with bread and with weapons and with stones, and to strengthen his house as much as possible, everyone being of the mind and intention to die fighting, and to slay anyone if needful, in the manner of the Sicilian Vespers. And fear was so widespread(2) that when at the dinner hour people began to say Serra, serra! (Shut everything!), it came about that the whole of Florence locked itself in, one fleeing here and another there, without any fresh cause or disturbance, the consequence being that many of the French rushed to the Porta a San Friano and took possession of the Ponte alia Carraia. And in Borgo Ognissanti and in Via Palazzuolo, and in Borgo San Friano, so many stones were thrown from the windows that they were not able to get to the gates; and when they asked the reason of it, no one knew. Therefore the king did not go to dine in the Palagio; and, by divine permission, the French became so uneasy that it caused them to change their evil intentions towards us who only had good ones. Anyone can see that God does not abandon Florence, but we are not sufficiently grateful. At this time we heard that the French troops which had been in Romagna were passing by in the neighbourhood of Dicomano.
(1) Some Florentines historians call him di Bles, and it was Philippe de Bresse, afterwards Duke of Savoy.
(2) The greatest confusion seems to have been caused by the Swiss, who were quartered near the Porta al Prato inside and out, and who tried to force their way through Borgo Ognissanti, in order to approach the king's quarters.
