And under these names the Italian cities many times suffered serious grievances and changes; and among the rest our city, which was sometimes at the head of one party, and sometimes of the other, according to the citizens in power; so much so that Dante’s ancestors, being Guelfs, were twice expelled by the Ghibellines from their home, and he likewise under the title of Guelf held the reins of the Florentine Republic, from which he was expelled, as we have shown, not by the Ghibellines, but by the Guelfs; and seeing that he could not return, he so much altered his mind that there never was a fiercer Ghibelline, or a bitterer enemy to the Guelfs, than he was. And that which I feel most ashamed at for the sake of his memory is, that it was a well-known thing in Romagna, that if any boy or girl, talking to him on party matters, condemned the Ghibelline side, he would become frantic, so that if they did not be silent he would have been induced to throw stones at them; and with this violence of party feeling he lived until his death. I am certainly ashamed to tarnish with any fault the fame of such a man; but the order of my subject in some degree demands it, because if I were silent in those things in which he was to blame, I should not be believed in those things I have already related in his praise.
