Grand Masters of the Priory of Sion

The mythical Priory of Sion was supposedly led by a "Nautonnier", an Old French word for a navigator, which means Grand Master in their internal esoteric nomenclature. The following list of Grand Masters is derived from the Dossiers Secrets d'Henri Lobineau compiled by Pierre Plantard (1920-2000) under the nom de plume of "Philippe Toscan du Plantier" in 1967. All those named on this list had died before that date. The names of most of these men are also found on lists of alleged “Imperators” (supreme heads) and/or “distinguished members” of the various Rosicrucian orders operating in England, France and Germany. Also, most of those named share the common characteristic of being known for having an interest in mysticism and/or the occult.

The Dossiers Secrets state that the Priory of Sion and the Knights Templar always shared the same Grand Master until a schism occurred during the "Cutting of the Elm" incident in 1188 A.D. Following that event, the Grand Masters of the Priory of Sion are identified as follows:

1.  Jean de Gisors (1188–1220)
