The Bijāpūr monument was built under similar circumstances a few years before Shah Jahān commenced the wonderful memorial to his beloved wife.

In order to understand the history of the Mogul or of any Indo-Muhammadan school of building, one must first consider the effect of Islam's war-like propaganda upon the building traditions of India. Before the Muhammadan conquest the Indian hereditary builders, whose traditions of technique and design went back in an unbroken line to some of the most ancient cities of the world, had for many centuries borrowed no structural ideas from outside India, but kept strictly to the craft ritual laid down in their own sacred writings. Though it is written in the Silpa-Sāstrās that the master-builder should be "conversant with all the sciences," it is probable that, as in the present day, every branch of the Indian building craft had become highly specialised, common traditions co-ordinating the different branches and preserving unity of structure and design.
Many centuries of practice within these lines had developed extraordinary technical skill without exhausting the immense fertility of invention possessed by the
