In the year of Christ 1282, the city of Florence being under government of the order of the fourteen good men as the Cardinal Latino had left it, to wit eight Guelfs and six Ghibellines, as we afore made mention, it seemed to the citizens that this government of fourteen was too numerous and confused; and to the end so many divided hearts might be at one, and, above all, because it was not pleasing to the Guelfs to have the Ghibellines as partners in the government by reason of the events which were come to pass (such as the loss which King Charles had already sustained of the island of Sicily, and the coming into Tuscany of the imperial vicar, and likewise the wars begun in Romagna by the count of Montefeltro on the Ghibelline side), for the safety and welfare of the city of Florence they annulled the said office of the fourteen and created and made a new office and lordship for the government of the said city of Florence, to wit, the Priors of the Arts; the which name, Priors of the Arts, means to say "the first," chosen over the others; and it was taken from the Holy Gospel, where Christ says to His disciples, "Vos estis priores."

And they were shut up to give audience (sleeping and eating at the charges of the commonwealth), in the house of the Badia where formerly, as we have aforesaid, the Ancients were wont to assemble in the time of the old Popolo, and afterwards the fourteen. And there were assigned to the said priors six constables and six messengers to summon the citizens; and these priors, with the Captain of the Popolo, had to determine the great and weighty matters of the commonwealth, and to summon and conduct councils and make regulations. And when the office had endured the two months, it was pleasing to the citizens; and for the following two months they proclaimed six, one for each sesto, and added to the said three greater Arts the art of the doctors and apothecaries, and the art of the Porta Santae Mariae, and that of the furriers and skin-dressers; and afterwards from time to time all the others were
