[extract] ... This article will discuss brick temples at two little known sites. A couple of years ago, I gave a talk in Ahmedabad attended by Professor M.A. Dhaky and, among slides of dozens of temples, showed an image of one of the temples in question, from Kalayat, Kaithal District, Haryana. This was the only one that Dhaky did not know – a good reason to make it the starting point for a contribution to this volume. The other site is some 500 km to the south-east of Kalayat, at Nasirabad in Sitapur District, Uttar Pradesh. Both sites belong to the era when northern India was dominated by the Pratīhāra dynasty, and both in different ways fill gaps in our knowledge of the Nāgara tradition of temple architecture (see Map). As well as publishing the unpublished and filling in knowledge, this paper will consider the question of how the material used for the construction of a temple affects its design.
