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? The very nature of its alleged action was such as utterly to conceal the hand that had administered it; yet here, on the first recorded occasion of its alleged use, it was more or less common knowledge if Giovio and Guicciardini are to be believed! Sagredo(1) says that Djem died at Terracina three days after having been consigned to Charles VIII, of poison administered by Alexander, to whom Bajazet had promised a large sum of money for the deed. The same is practically Giovio’s statement, save that Giovio causes him to die at a later date and at Gaeta; Guicciardini and Corio tell a similar story, but inform us that he died in Naples. 1 In Mem. Storiche dei Monarchi Ottomani. It is entirely upon the authority of these four writers that the Pope is charged with having poisoned Djem, and it is noteworthy that in the four narratives we find different dates and three different places given as the date and place of the Turk’s death, and more noteworthy still that in not one instance of these four is date or place correctly stated.
