personal loves and hates; or else for centuries past we have accorded unmerited praise to the historians who have described impossible events to us in the most vivid colours. In fact, how could it possibly be that so much good sense should breed so much disorder? How, too, in the midst of this disorder, with the vessel of the State at the mercy of every wind that blew, could art, science, and literature give forth so glorious a harvest? Undoubtedly history, as we interpret it to-day, was unknown to the ancients. We seek the causes of events, whereas they merely described them. We wish to know the laws, manners, ideas, and prejudices of mankind, whereas our forefathers were exclusively concerned with human passions and actions. In the fifteenth century political science was chiefly a study of human nature, while at this day it is mainly a study of institutions. Modern history aims at the examination of mankind and society in every form, and from every point of view. That is why we have had to so often re-fashion the work that, nevertheless, had been splendidly performed by writers of old. Leaving aside all compilers of those fables and legends on the origin of Florence found repeated in even later works, Florentine historians may be divided into two great schools. First come the authors of Chronicles or Diaries, who flourished chiefly in the fourteenth century, although they continued long after that period. These writers record day by day the events they have witnessed and in which they have often taken part; stirred by the very passions they describe, they sometimes rise to eloquence, and the heat of their own words leaves them no time to dwell on abstract ideas. They presuppose in their readers their own detailed knowledge of the political institutions among which their lives were spent, but which are unknown to us, and the object of our keenest desire. Frequently, however, some fourteenth-century chronicler, such as Giovanni Villani, with his incomparable gift of observation, supplies such minute descriptions of events, reports so many details, that, almost unawares, we find ourselves carried back to his day. Sometimes, when descending to particulars, he apologises for detaining the reader on topics of small moment, little foreseeing what value we later generations would attach to all those details of the trade, instruction, revenue, and expenditure of the Republic, or how we should long for more facts of the same kind. But as soon as these writers touch upon times and events outside their own experience, they have either to copy verbatim from other chroniclers, or their narratives remain cold, colourless, and devoid of merit or authority. We pass at once from the most lively and graphic descriptions to the strangest fables, the greatest incoherence, since these men are incapable of using any discernment even in copying literally from others. Proofs of this are seen in their puerile accounts of the foundation of Florence.
