of Arezzo, about the year 1450 was made secretary of the Emperor Frederick III. He died at Padua in 1467, leaving a work entitled Monarchia, in five parts, on the powers of the emperor and the pope, in which he endeavors to show that the pope has not authority in temporal matters, and that in spiritual affairs he is subject to the Church. This remarkable work was printed at Venice in 1483, 1587, and is to be found in Goldastus, Monarch. 1, 252-556. It is, of course, placed upon the Index Expurgatorius. — Cave, Hist.
