Du Junca kept two private registers: in the first he recorded those who entered the Bastille; in the second he recorded those who left, either by being freed or by dying. His entry for the mysterious prisoner, who had long ago lost his name and his identity, reads:

In the margin, Du Junca added: ‘I have since learned that they named him on the register M de Marchiel; that they paid 40 livres for the funeral.'
The prisoner was indeed buried on 20 November 1703 in the churchyard of Saint-Paul-des-Champs. This was, as Du Junca noted, the parish church which served the Bastille, Situated on what is today the corner of the rue Saint-Paul and rue Neuve Saint-Pierre, it was closed in 1790 and its register was destroyed in a fire set by the Communards in May 1871. Happily, the register's contents had already been copied by historians. The entry for the Iron Mask's burial read:
'On the 19th [November], Marchioly, aged 45 years or thereabouts, died at the Bastille, whose body was buried in the churchyard of St. Paul, his parish, the 20th of the present month, in the presence of M. Reglhe [sic], surgeon major of the Bastille, who signed.’
It was then signed by Rosarges and Reilhe.
