Stefano Infessura was born at Rome circa 1435 and died there circa 1500. This turbulent spirit was entangled in the conspiracy of Stefano Porcaro against Nicholas V (1453), which aimed at overturning the Papal government and making Rome a republic. His violent bias makes his “Diarium urbis Rome,” a chronicle from 1294 to 1494 (written partly in Latin and partly in Italian), of little value, as he did not hesitate to reproduce any idle scandal, and even to invent notorious calumnies, concerning such Pontiffs as Sixtus IV and Innocent VIII.
