Gaspare Fossati - Louis Haghe - Vue générale de la grande nef, en regardant l'occident (Hagia Sophia - Ayasofya Mosque nave), Louis Haghe, 1852

"vue générale de la grande nef, en regardant l'occident" - an illustration of the nave of the ayasofya mosque/hagia sophia from the period when it was in use as a mosque. This appears to be a very accurate depiction, compare this (somewhat badly degraded) photograph from fifty years later. Date: 1852.
