"As Mahoba was for some time the headquarters of the early Muhammadan Governors, we could hardly expect to find that any Hindu buildings had escaped their furious bigotry, or their equally destructive cupidity. When the destruction of a Hindu temple furnished the destroyer with the ready means of building a house for himself on earth, as well as in heaven, it is perhaps wonderful that so many temples should still be standing in different parts of the country. It must be admitted, however, that, in none of the cities which the early Muhammadans occupied permanently, have they left a single temple standing, save this solitary temple at Mahoba, which doubtless owed its preservation solely to its secure position amid the deep waters of the Madan-Sagar. In Delhi, and Mathura, in Banaras and Jonpur, in Narwar and Ajmer, every single temple was destroyed by their bigotry, but thanks to their cupidity, most of the beautiful Hindu pillars were preserved, and many of them, perhaps, on their original positions, to form new colonnades for the masjids and tombs of the conquerors."
