from Rome, I began to compile this book, in reverence to God and the blessed John, and in commendation of our city of Florence. [Sidenote: 1300 A.D.] Sec. 37.--_How Count Guido of Flanders and two sons of his surrendered to the king of France, and how they were deceived and cast into prison._ Sec. 38.--_How the parties of the Blacks and Whites first began in the city of Pistoia._ [Sidenote: 1300 A.D.] In these times the city of Pistoia being in happy and great and good estate, among the other citizens there was one family very noble and puissant, not however of very ancient lineage, which was called the Cancellieri, born of one Ser Cancelliere, which was a merchant, and gained much wealth, and by his two wives had many sons, which by reason of their riches all became knights, and men of worth and substance, and from them were born many sons and grandsons, so that at this time they numbered more than 100 men in arms, rich and puissant and of many affairs, so that not only were they the leading citizens of Pistoia, but they were among the most puissant families of Tuscany.

By which sinful beginning, not only was the house of the Cancellieri divided, but many violent deaths arose therefrom, and all the city of Pistoia was divided, for some held with one part and some with the other, and they called themselves the Whites and the Blacks, forgetting among themselves the Guelf and Ghibelline parties; and many civil strifes and much peril and loss of life arose therefrom in Pistoia; and not only in Pistoia, but afterwards the city of Florence and all Italy was contaminated by the said parties, as hereafter we shall be able to understand and know. The Florentines, fearing lest the said factions should stir up rebellion in the city to the hurt of the Guelf party, interposed to bring about an atonement between them, and took the lordship of the city, and brought both parties of the Cancellieri from Pistoia, and set them under bounds at Florence. The Black party were kept in the house of the Frescobaldi in Oltrarno, and
