Domenico di Leonardo Buoninsegni's Istoria Fiorentina has served numerous historians of Renaissance Florence as a source for the political events which occurred in that city in the Trecento and Quattrocento. Being a narration of Florentine history from the Creation to the autumn of 1460 it has provided modern scholars with numerous details which, seemingly, offered fresh and original insights into the evolution of Florentine history, particularly for the later portion of the Istoria in which the events described coincided with the life of the author himself (b. 1384—d. 1465).
Unfortunately, since its first partial publication by Giorgio Marescotti in 1580 (reissued in 1581), Buoninsegni's Istoria has been subject to a series of misunderstandings and misinterpretations on one of which, ironically, has rested its reputation among scholars.
