Note 540 — THE VISION OF JUDGMENT. BY QUEVEDO REDIVIVUS.
Reading edition
[The "Man in the Iron Mask," or, more correctly, the "Man in the Black Velvet Mask," has been identified with Count Ercole Antonio Mattioli, Secretary of State at the Court of Ferdinando Carlo Gonzaga, Duke of Mantua. Mattioli was convicted of high treason, and at the instance of Louis XIV. was seized by the Maréchal Catinat, May 2, 1679, and confined at Pinerolo. He was deported to the Iles Sainte-Marguerite, March 19, 1694, and afterwards transferred to the Bastille, September 18, 1698. He died November 19, 1703. Baron Heiss was the first to solve the mystery. Chambrier, Roux-Fazillac, Delort, G. A. Ellis (see a notice in the Quart. Rev., June, 1826, vol. xxxiv. p. 19), and others take the same view. (See, for confirmation of this theory, an article L'Homme au Masque de Velours Noir, in the Revue Historique, by M. Frantz Funck-Brentano, November, December, 1894, tom. 56, pp. 253-303.)]
