"There is no inscription on the building (Jama Masjid at Mathura), but people ascribe it to Aurungzib, who is said to have pulled down the great Hindu temple of Kesava Deva or Keso Ray, that formerly stood on this high mound, a most noble position, which commands a fine view of the whole city. Curiously enough I have been able to verify this charge against Aurungzib by means of some inscriptions on the pavement slabs, which were recorded by Hindu pilgrims to the shrine of Kesava Ray. In relaying the pavement the Muhammadan architect was obliged to cut many of the slabs to make them fit into their new places. This was proved by several slabs bearing incomplete portions of Nagari inscriptions of a late date. One slab has ‘bat. 1713, Phalgun,’ the initial Sam of Sambat having been cut off. Another slab hes the name of Keso Ray, the rest being wanting; while a third bears the date of S. 1720. These dates are equivalent to ‘A.D. 1656 and 1663; and, as the latter is five years subsequent to the accession of Aurangzeb, it is certain that the Hindu temple was still standing at the beginning, of his reign."
