Theories & Explanations

  • The Ercole Mattioli Theory contradicts The Eustache Dauger Theory — The Dauger reading treats the prisoner as a low-status valet jailed for what he knew; the Mattioli reading rests on the burial register name 'Marchioly' and casts him as a disgraced diplomat, an identity of a different order entirely.

Places
