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.
