The striking talents of Gregorovius are occasionally marred by the egotism and pedantry sometimes characteristic of the scholars of his nation. He is too positive; he seldom opines; he asserts with finality the things that only God can know; occasionally his knowledge, transcending the possible, quits the realm of the historian for that of the romancer, as for instance--to cite one amid a thousand--when he actually tells us what passes in Cesare Borgia’s mind at the coronation of the King of Naples. In the matter of authorities, he follows a dangerous and insidious eclecticism, preferring those who support the point of view which he has chosen, without a proper regard for their intrinsic values. He tells us definitely that, if Alexander had not positive knowledge, he had at least moral conviction that it was Cesare who had killed the Duke of Gandia. In that, again, you see the God-like knowledge which he usurps; you see him clairvoyant rather than historical. Starting out with the positive assertion that Cesare Borgia was the murderer, he sets himself to prove it by piling up a mass of worthless evidence, whose worthlessness it is unthinkable he should not have realized. “According to the general opinion of the day, which in all probability was correct, Cesare was the murderer of his brother.” Thus Gregorovius in his Lucrezia Borgia. A deliberate misstatement! For, as we have been at pains to show, not until the crime had been fastened upon everybody whom public opinion could conceive to be a possible assassin, not until nearly a year after Gandia’s death did rumour for the first time connect Cesare with the deed. Until then the ambassadors’ letters from Rome in dealing with the murder and reporting speculation upon possible murderers never make a single allusion to Cesare as the guilty person. Later, when once it had been bruited, it found its way into the writings of every defamer of the Borgias, and from several of these it is taken by Gregorovius to help him uphold that theory. Two motives were urged for the crime. One was Cesare’s envy of his brother, whom he desired to supplant as a secular prince, fretting in the cassock imposed upon himself which restrained his unbounded ambition. The other--and no epoch but this one under consideration, in its reaction from the age of chivalry, could have dared to level it without a careful examination of its sources--was Cesare’s jealousy, springing from the incestuous love for their sister Lucrezia, which he is alleged to have disputed with his brother. Thus, as l’Espinois has pointed out, to convict Cesare Borgia of a crime which cannot absolutely be proved against him, all that is necessary is that he should be charged with another crime still more horrible of which even less proof exists.
