"For the credit of the city, the name of the duke of Athens ought to be consigned to oblivion. His cruel and tyrannical disposition, however, might have taught us wisdom and instructed us how to live; but no sooner was he expelled than we handled our arms, and fought with more hatred, and greater fury than we had ever done on any former occasion; so that the ancient nobility were vanquished the city was left at the disposal of the people. It was generally supposed that no further occasion of quarrel or of party animosity could arise, since those whose pride and insupportable ambition had been regarded as the causes of them were depressed; however, experience proves how liable human judgment is to error, and what false impressions men imbibe, even in regard to the things that most intimately concern them; for we find the pride and ambition of the nobility are not extinct, but only transferred from them to the people who at this moment, according to the usual practice of ambitious men, are endeavoring to render themselves masters of the republic; and knowing they have no chance of success but what is offered by discord, they have again divided the city, and the names of Guelph and Ghibelline, which were beginning to be forgotten (and it would have been well if they had never been heard among us), are repeated anew in our ears. "It seems almost necessarily ordained, in order that in human affairs there may be nothing either settled or permanent, that in all republics there are what may be called fatal families, born for the ruin of their country. Of this kind of pest our city has produced a more copious brood than any other; for not one but many have disturbed and harassed her: first the Buondelmonti and the Uberti; then the Donati and the Cerchi; and now, oh ridiculous! oh disgraceful thought! the Ricci and the Albizzi have caused a division of her citizens.
