Mosque of Omar
Foucault's PendulumThe Mosque of Omar is presented as the possible site of the Plan’s sixth appointment in Jerusalem. In the characters’ reconstruction, a message to go to “the stone” points to the rock venerated by Muslims at the mosque’s center, turning a religious landmark into a coded destination in their imagined Templar itinerary.
The Stone as a Clue
The argument depends on a specific feature of the site: its central rock is sacred to Muslims, and visitors must remove their shoes to see it. The speaker treats these details as the key to the message’s otherwise spare direction to go to the stone. The place is not merely a name on a route; its distinct ritual and religious character supplies the clue that makes the identification seem persuasive.
Place in the Reconstructed Route
The mosque is associated in the account with the former site of the Templars’ Temple. That juxtaposition lets the speaker connect the Muslim-venerated rock to the Templars’ history in Jerusalem and designate the city as the Plan’s sixth appointment. Jerusalem becomes the route’s intended endpoint, while the mosque provides the precise landmark at which the imagined meeting might occur.
The speaker does not claim to know who would have waited there. The possibilities offered are a surviving, disguised Templar core group or a cabal of Kabbalists connected with the Portuguese. This uncertainty remains unresolved even as the route is presented as logical: from Germany, it would pass through the Balkans, where the reconstructed fifth group was supposed to be waiting.
Narrative Significance
The mosque’s role belongs to a speculative reconstruction voiced as an explanation of the Plan, not to a confirmed historical meeting. Its persuasive force comes from joining a terse instruction, a distinctive sacred object, and the Templars’ association with the site. Belbo says he is persuaded, showing how the chain of interpretation can make the Plan seem straightforward and economical; the unidentified people supposedly awaiting the group, however, preserve a gap the explanation cannot close.
