Note 1523 — Chapter VII
Reading edition
Von Raumer, who has given an analysis of this letter of Antonio Perez, treats it lightly, as coming from "a double-dealing, bitter enemy of Philip," whose word on such a subject was of little value. (Sixteenth and Seventeenth Centuries, vol. I. p. 155.) It was certainly a singular proof of confidence in one who was so habitually close in his concerns as the prince of Eboli, that he should have made such a communication to Perez. Yet it must be admitted that the narrative derives some confirmation from the fact, that the preceding portions of the letter containing it, in which the writer describes the arrest of Carlos, conform with the authentic account of that event as given in the text.
It is worthy of notice, that both De Thou and Llorente concur with Perez in alleging poison as the cause of the prince's death. Though even here there is an important discrepancy; Perez asserting it was a slow poison, taking four months to work its effect, while the other authorities say that its operation was immediate. Their general agreement, moreover, in regard to the employment of poison, is of the less weight, as such an agency would be the one naturally surmised under circumstances where it would be desirable to leave no trace of violence on the body of the victim.
