The testimony of these two men is tainted. Messer Francesco Guicciardini, who wrote long after the event and solely from hearsay, was a Florentine. Whatever is, and was, of Florence, is cultured, pedantic, artificial, in the highest degree: whatever is, and was, of Rome, is nakedly natural, original, free, and absolute, in the highest degree. It was, and is, a habit of mind in the Florentine to decry Rome and all things Roman. Politically, Messer Francesco Guicciardini was an adherent of the House of Medici; and Medici were naturally the mortal foes of Borgia, seeing that Borgia had acquiesced in and profited by their expulsion from Florence. And he was in the pay of the Roman Colonna, who were Ghibelline by inherited tradition, _i.e._, upholders of the imperial against the papal prerogative. He was born in 1482; and was of the age of twenty-one years at the death of the Lord Alexander P.P. VI. In 1530, having exhorted the Lord Clement P.P. VII to punish Florence for insults which he (Guicciardini) had received in 1527, he turned traitor against the Medici, writing invectives against them till his death in 1540. He divinely wrote at all times a sonorous and courtly Tuscan, which makes his reader believe that one who could write so exquisitely must needs write truly. Yet he did not hesitate to boast that he had a pen of gold for his friends, and a pen of iron for his foes. Regretfully then it must be said that Messer Francesco Guicciardini does not deserve belief unless his statements can be corroborated. Touching the matter of the Borgia venom, and especially of the envenoming of the Lord Alexander P.P. VI and Duke Cesare, he is corroborated by Messer Paolo Giovio. Messer Paolo Giovio was born in 1483, and was of the age of twenty years at the death of the Lord Alexander P.P. VI. He issued no books till twenty-one years later. His first was a quoad-scientific treatise on Roman Fishes (_De Piscibus Romanis_), published in 1524. He was a _dilettante_ of a kind. He practised amniomancy, or the art of divination by inspection of the membrane, Amnios, in which the unborn child is wrapped—fantastic effort of a seeker after Truth. He was one of those double-faced historians, who wrote one set of memoirs for the highest bidder; (Popes whom they despised, Dukes whom they privately reviled,) and a second set of memoirs for the enemies of the patrons of the first. His Life of the Lord Leo P.P. X (Giovanni de’ Medici) is a specimen. Even during his life, he was considered to be a flagrant liar. He used to say, with a dog-like knowledge of his masters the “people” who “desire to be deceived,” that the centuries would give his written lies the force of truth. He used an affected and flamboyant rather than a pure style; and was the inferior of Guicciardini. The Lord Clement P.P. VII (Giulio de’ Medici), to be rid of his incessant importunity, gave him the bishopric of Nocera; and he died in 1552.
