To sum up, on July 1, 1669, the valet of the Huguenot intriguer,
Roux de Marsilly, the valet resident in England, known to his master
as 'Martin,' was 'wanted' by the French secret police. By July 19,
a valet, of the highest political importance, had been brought to
Dunkirk, from England, no doubt. My hypothesis assumes that this
valet, though now styled 'Eustache Dauger,' was the 'Martin' of Roux
de Marsilly. He was kept with so much mystery at Pignerol that
already the legend began its course; the captive valet was said to
be a Marshal of France! We then follow Dauger from Pignerol to Les
Exiles, till January 1687, when one valet out of a pair, Dauger
being one of them, dies. We presume that Dauger is the survivor,
because the great mystery still is 'what he HAS DONE,' whereas the
other valet had done nothing, but may have known Dauger's secret.
Again, the other valet had long been dropsical, and the valet who
died in 1687 died of dropsy.

In 1688, Dauger, at Sainte-Marguerite, is again the source and
centre of myths; he is taken for a son of Oliver Cromwell, or for
the Duc de Beaufort. In June 1692, one of the Huguenot preachers at
Sainte-Marguerite writes on his shirt and pewter plate, and throws
them out of window.* Legend attributes these acts to the Man in the
Iron Mask, and transmutes a pewter into a silver plate. Now, in
1689-1693, Mattioli was at Pignerol, but Dauger was at Sainte-
Marguerite, and the Huguenot's act is attributed to him. Thus
Dauger, not Mattioli, is the centre round which the myths
crystallise: the legends concern HIM, not Mattioli, whose case is
well known, and gives rise to no legend. Finally, we have shown
that Mattioli probably died at Sainte-Marguerite in April 1694. If
so, then nobody but Dauger can be the 'old prisoner' whom Saint-Mars
brought, masked, to the Bastille, in September 1698, and who died
