The letters in this volume span just 17 months from 13th April 1491 to 13th September 1492. This period marked a critical time for the whole of Florence, occasioned by the death of Lorenzo de' Medici. The youth and inexperience of his son and successor, Piero, led to discontent and instability, a situation that would soon be exploited by the rdadical reforming friar Girolamo Savonarola. On the other hand it was a period of prolific creativity in literature and the arts, described by Ficino as a 'golden age'. 1491 saw the publicaiton of important works in philosophy by Pico della Mirandola and in philology by Poliziano. Ficino himself brought out his great translation of Plotinus with the commentary that had occupied him for several years.
