After this declaration Voltaire made no further reference to the Iron Mask. This last version of the story upset that of Sainte-Foix. Voltaire having been initiated into the state secret by the Marquis de Richelieu, we may be permitted to suspect that being naturally indiscreet he published the truth from behind the shelter of a pseudonym, or at least gave a version which approached the truth, but later on realising the dangerous significance of his words, he preserved for the future complete silence.
We now approach the question whether the prince who thus became the Iron Mask was an illegitimate brother or a twin-brother of Louis XIV. The first was maintained by M.

She even permitted him to take off and keep one of her gloves, and his vanity leading
