The mystical mathematics were well known to the Sufi craftsmen who designed this part of the mosque. Their system of mathematics was called abjad, and provided a conceptual springboard from which the diverse and inventive geometrical patterns in the roof vaults were derived. Originally it was probably a huge library, but after the siege of Isfahan by Toghril Begh, during which large parts of the mosque were ransacked to provide winter fuel, it was rebuilt in its present form. Reconstruction is still taking place - extensive damage was suffered in this part of the mosque during the Iran-Iraq war, and craftsmen are still repairing much of the brickwork by hand.
It was amongst these strange cloisters that one of the greatest Iranians of all time, Nizam Al Mulk, the vizier of Malek Shah and friend and patron of Omar Khayyam, chose to erect his prayer chamber.
