With the exception of Dulaure, all the critics have treated Soulavie’s narrative with the most profound contempt, and we must confess that if it was an invention it was a monstrous one, and that the concoction of the famous note in cipher was abominable. “Such was the great secret; in order to find it out, I had to allow myself 5, 12, 17, 15, 14, 1, three times by 8, 3.” But unfortunately for those who would defend the morals of Mademoiselle de Valois, it would be difficult to traduce the character of herself, her lover, and her father, for what one knows of the trio justifies one in believing that the more infamous the conduct imputed to them, the more likely it is to be true. We cannot see the force of the objection that Louvois would not have written in the following terms to Saint-Mars in 1687 about a bastard son of Anne of Austria: “I see no objection to your removing Chevalier de Thezut from the prison in which he is confined, and putting your prisoner there till the one you are preparing for him is ready to receive him.” And we cannot understand those who ask if Saint-Mars, following the example of the minister, would have said of a prince “Until he is installed in the prison which is being prepared for him here, which has a chapel adjoining”? Why should he have expressed himself otherwise? Does it evidence an abatement of consideration to call a prisoner a prisoner, and his prison a prison?

A certain M. de Saint-Mihiel published an 8vo volume in 1791, at Strasbourg and Paris, entitled ‘Le veritable homme, dit au MASQUE DE FER, ouvrage dans lequel on fait connaitre, sur preuves incontestables, a qui le celebre infortune dut le jour, quand et ou il naquit’. The wording of the title will give an idea of the bizarre and barbarous jargon in which the whole book is written. It would be difficult to imagine the vanity and self-satisfaction which inspire this new reader of riddles. If he had found the philosopher’s stone, or made a discovery which would transform the world, he could not exhibit more pride and pleasure. All things considered, the “incontestable proofs” of his theory do not decide the question definitely, or place it above all attempts at refutation, any more than does the evidence on which the other theories which preceded and followed his rest. But what he lacks before all other things is the talent for arranging and using his materials. With the most ordinary skill he might have evolved a theory which would have defied criticism at least as successfully, as the others, and he might have supported it by proofs, which if not incontestable (for no one has produced such), had at least moral presumption in their favour, which has great weight in such a mysterious and obscure affair, in trying to explain, which one can never leave on one side, the respect shown by Louvois to the prisoner, to whom he always spoke standing and with uncovered head.

According to M. de Saint-Mihiel, the ‘Man in the Iron Mask was a legitimate son of Anne of Austria and Mazarin’.

He avers that Mazarin was only a deacon, and not a priest, when he became cardinal, having never taken priest’s orders, according to the testimony of the Princess Palatine, consort of Philip I, Duc d’Orleans, and that it was therefore possible for him to marry, and that he did marry, Anne of Austria in secret.

“Old Madame Beauvais, principal woman of the bed-chamber to the queen mother, knew of this ridiculous marriage, and as the price of her secrecy obliged the queen to comply with all her whims. To this circumstance the principal bed-chamber women owe the extensive privileges accorded them ever since in this country” (Letter of the Duchesse d’Orleans, 13th September 1713).

“The queen mother, consort of Louis XIII, had done worse than simply to fall in love with Mazarin, she had married him, for he had never been an ordained priest, he had only taken deacon’s orders. If he had been a priest his marriage would have been impossible. He grew terribly tired of the good queen mother, and did not live happily with her, which was only what he deserved for making such a marriage” (Letter of the Duchesse d’Orleans, 2nd November 1717).

“She (the queen mother) was quite easy in her conscience about Cardinal Mazarin; he was not in priest’s orders, and so could marry. The secret passage by which he reached the queen’s rooms every evening still exists in the Palais Royal” (Letter of the Duchesse d’Orleans, 2nd July 1719)

“The queen’s, manner of conducting affairs is influenced by the passion which dominates her. When she and the cardinal converse together, their ardent love for each other is betrayed by their looks and gestures; it is plain to see that when obliged to part for a time they do it with great reluctance. If what people say is true, that they are properly married, and that their union has been blessed by Pere Vincent the missioner, there is no harm in all that goes on between them, either in public or in private” [‘Requete civile contre la Conclusion de la Paix, 1649).

The Man in the Iron Mask told the apothecary in the Bastille that he thought he was about sixty years of age [‘Questions sur d’Encyclopedie’). Thus he must have been born in 1644, just at the time when Anne of Austria was invested with the royal power, though it was really exercised by Mazarin.

Can we find any incident recorded in history which lends support to the supposition that Anne of Austria had a son whose birth was kept as secret as her marriage to Mazarin?
