Poggio Bracciolini’s last work, the Historiae Florentini populi, was edited and dedicated to Federico di Montefeltro by Jacopo di Poggio in 1472. Jacopo also translated the work into the volgare and had it printed in Venice in 1476. In the light of the manuscript tradition, Jacopo’s editorial changes were more considerable than has hitherto been thought. The propagation of his edition and translation would seem to be intimately connected with his political aspirations ending in his unfortunate participation in the Pazzi conspiracy of 1478.
