Both men were endeavouring to exculpate themselves, and therefore both statements are subject to suspicion.
He was one of the Scots who met Elizabeth's representatives at York in 1568; here he showed a desire to exculpate Mary and to marry her to the duke of Norfolk, a course of action probably dictated by a desire to avoid all revelations about the Darnley murder.
The notes' bearing upon the interview which he obtained with the king show that he had begun to see more clearly the nature and extent of the offences with which he was charged, that he now felt it impossible altogether to exculpate himself, and that his hopes were directed towards obtaining some mitigation of his sentence.
It also created a great impression in England, where it was believed that the Bandieras' correspondence with Mazzini (q.v.) had been tampered with, and that information as to the proposed expedition had been forwarded to the Austrian and Neapolitan governments by the British foreign office; recent publications, however, especially the biography of Sir James Graham, tend to exculpate the British government.
On the other hand, it is urged that, though Guyon and Du Verdier were in a sense contemporaries, they wrote long after the events, and that the testimony of the former is vitiated, not merely by its extreme vagueness, but by the fact .that it occurs in a plaidoyer, tending to exculpate physicians from the charge of unorthodoxy; that Du Verdier in another place assigns the Pantagrueline Prognostication to this same unknown student of Valence, and had therefore probably confused and hearsay notions on the subject; that the rasher and fiercer tone, as well as the apparent repetitions, are sufficiently accounted for on the supposition that Rabelais never finally revised the book, which indeed dates show that he could not have done, as the fourth was not finally settled till just before his death; and that it is perfectly probable, and indeed almost certain, that it was prepared from his papers by another hand, which is responsible for the anachronous allusions above referred to.
