the hypostyle prayer halls of the friday mosque are a patchwork of different domes and vaults - and not only because of its long building history; it is the result of a design decision in the middle ages to celebrate the talented persian masons or rather: to allow the talented persian masons to celebrate God through their craft.
in this, the northwest prayer hall, every single dome is done to a different design. you will recognize the ribs from the great mosque in cordoba quoted above. behind it, a local iranian muqarnas design. an encyclopedia indeed.
in its ability to take on various functions without compromising the overall design; the way individual artisans display their craft; the respect of its ancient history in every one of its added layers; and finally in the brilliant incrustation of its central courtyard, the friday mosque appears to the european visitor as the ultimate ruskinian monument.
