“This anxiety, caused by the pressure of public business, was most probably only dwelt on as a pretext for a pretended attack of illness.  Anne of Austria had no cause for worry and anxiety till 1649.  She did not begin to complain of the despotism of Mazarin till towards the end of 1645” (Ibid., viol. i. pp. 272, 273).

“She went frequently to the theatre during her first year of widowhood, but took care to hide herself from view in her box.” (Ibid., vol. i. p. 342).

Abbe Soulavie, in vol. vi. of the ‘Memoires de Richelieu’, published in 1793, controverted the opinions of M. de Saint-Mihiel, and again advanced those which he had published some time before, supporting them by a new array of reasons.

The fruitlessness of research in the archives of the Bastille, and the importance of the political events which were happening, diverted the attention of the public for some years from this subject.  In the year 1800, however, the ‘Magazin encyclopedique’ published (vol. vi. p. 472) an article entitled ’Memoires sur les Problemes historiques, et la methode de les resoudre appliquee a celui qui concerne l’Homme au Masque de Fer’, signed C. D. O., in which the author maintained that the prisoner was the first minister of the Duke of Mantua, and says his name was Girolamo Magni.

In the same year an octavo volume of 142 pages was produced by M. Roux-Fazillac.  It bore the title ’Recherches historiques et critiques sur l’Homme au Masque de Fer, d’ou resultent des Notions certaines sur ce prisonnier’.  These researches brought to light a secret correspondence relative to certain negotiations and intrigues, and to the abduction of a secretary of the Duke of Mantua whose name was Matthioli, and not Girolamo Magni.

In 1802 an octavo pamphlet containing 11 pages, of which the author was perhaps Baron Lerviere, but which was signed Reth, was published.  It took the form of a letter to General Jourdan, and was dated from Turin, and gave many details about Matthioli and his family.  It was entitled ‘Veritable Clef de l’Histoire de l’Homme au Masque de Fer’.  It proved that the secretary of the Duke of Mantua was carried off, masked, and imprisoned, by order of Louis XIV in 1679, but it did not succeed in establishing as an undoubted fact that the secretary and the Man in the Iron Mask were one and the same person.

It may be remembered that M. Crawfurd writing in 1798 had said in his ‘Histoire de la Bastille’ (8vo, 474 pages), “I cannot doubt that the Man in the Iron Mask was the son of Anne of Austria, but am unable to decide whether he was a twin-brother of Louis XIV or was born while the king and queen lived apart, or during her widowhood.”  M. Crawfurd, in his ‘Melanges d’Histoire et de Litterature tires dun Portefeuille’ (quarto 1809, octavo 1817), demolished the theory advanced by Roux-Fazillac.

In 1825, M. Delort discovered in the archives several letters relating to Matthioli, and published his Histoire de l’Homme au Masque de Fer (8vo).  This work was translated into English by George Agar-Ellis, and retranslated into French in 1830, under the title ’Histoire authentique du Prisonnier d’Etat, connu sons le Nom de Masque de Fer’.  It is in this work that the suggestion is made that the captive was the second son of Oliver Cromwell.
