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.

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.
Now the place where Djem died, and the date of his death, were public facts about which there was no mystery; they were to be ascertained--as they are still--by any painstaking examiner. His poisoning, on the other hand, was admittedly a secret matter, the truth of which it was impossible to ascertain with utter and complete finality. Yet of this poisoning they know all the secrets, these four nimble writers who cannot correctly tell us where or when the man died!
