Cesare remained at Flores’s house, sending word to the Pope of his presence, but not attempting to approach the Vatican. On the following day he withdrew to the stronghold of Spoleto.
Meanwhile Rome was thrown into a panic by the young cardinal’s action and the dread of reprisals on the part of France. The quaking municipality sent representatives to Charles to assure him that Rome had had nothing to do with this breach of the treaty, and to implore him not to visit it upon the city. The king replied by a special embassy to the Pope, and there apparently dropped the matter, for a few days later Cesare reappeared at the Vatican.
Charles, meanwhile, despite the threats of Spain, pushed on to accomplish his easy conquest.
King Alfonso had already fled the kingdom (January 25), abdicating in favour of his brother Federigo. His avowed object was to withdraw to Sicily, retire from the world, and do penance for his sins, for which no doubt there was ample occasion. The real spur was probably—as opined by Commines—cowardice; for, says that Frenchman, “Jamais homme cruel ne fut hardi.”
Federigo’s defence of the realm consigned to him was not conspicuous, for the French entered Naples almost without striking a blow within twenty days of their departure from Rome.
Scarcely had Charles laid aside his armour when death robbed him of the second hostage he had brought from the Vatican. On February 25, after a week’s illness, Prince Djem died of dysentery at the Castle of Capua, whither Charles had sent him.
Rumours that he had been poisoned by the Pope arose almost at once; but, considering that twentyeight days had elapsed since his parting from Alexander, it was, with the best intentions in the world, rather difficult to make that poisoning credible, until the bright notion was conceived, and made public, that the poison used was a “white powder” of unknown components, which did its work slowly, and killed the victim some time after it had been administered. Thus, by a bold and brazen invention, an impossible falsehood was made to wear a possible aspect.
And in that you have most probably the origin of the famous secret poison of the Borgias. Having been invented to fit the alleged poisoning of Prince Djem, which it was desired to fasten upon the Pope by hook or by crook, it was found altogether too valuable an invention not to be used again. By means of it, it became possible to lay almost any death in the world at the door of Alexander.
Before proceeding to inquire further into this particular case, let us here and now say that, just as to-day there is no inorganic toxin known to science that will either lie fallow for weeks in the human system, suddenly to become active and slay, or yet to kill by slow degrees involving some weeks in the process, so none was known in the Borgian or any other era. Science indeed will tell you that the very notion of any such poison is flagrantly absurd, and that such a toxic action is against all the laws of nature.
But a scientific disquisition is unnecessary. For our present needs arguments of common sense should abundantly suffice. This poison—this white powder—was said to be a secret of the Borgias. If that is so, by what Borgia was the secret of its existence ever divulged? Or, if it never was divulged, how comes it to be known that a poison so secret, and working at such distances of time, was ever wielded by them?
