"Several of the temple-pillars existing in the mosque and pillar- bases unearthed in the excavations conducted in the south of the mosque (although in the adjoining plot of land) show the same directional alignment. This will convince any student of architecture that two sets of material remains belong to one and the same complex. Secondly, the archaeological history of Islamic glazed ware in India goes back to the eleventh century, not the fifteenth ; in the fifteenth only a particular type of glazed ware was brought to India. Here at Ayodhya one kind of Islamic glazed ware was even a local imitation of the thirteenth century. Therefore, when we observe that here we recovered Islamic glazed ware of different periods, from the thirteenth to the fifteenth century, from below the floor level of the mosque, we are telling the truth of archaeological discoveries."
