Up to the year 1857 the fame of Guicciardini as a writer, and the estimation of him as a man, depended almost entirely upon the History of Italy, and on a few ill-edited extracts from his aphorisms. At that date his representatives, the counts Piero and Luigi Guicciardini, opened their family archives, and cornmitted to Signor Giuseppe Canestrini the publication of his hitherto inedited MSS.
Portions of his correspondence have been printed at various times, and inedited letters from him are of frequent occurrence in public libraries.
It includes a mass of previously inedited correspondence and other documents, collected by the indefatigable director, Professor Antonio Favaro, among whose numerous publications on Galilean subjects may be mentioned: Galileo e lo studio di Padova (2 vols., 1883); Scampoli Galileani (12 series, 1886-1897); Nuovi Studii Galileani (1891); Galileo Galilei e Suor Maria Celeste (1891).
