Of the various forms which the Moslem architecture assumed, "that of Ahmedabad," Fergusson has justly remarked, "may probably be considered as the most elegant, as it certainly is the most characteristic of all. No other form is so essentially Indian, and no one tells its tale with the same unmistakable distinctness." Under the Mahommedan rule the Hindu architects employed introduced forms and ornaments into the works they constructed for their rulers, superior in elegance to any the latter knew or could have invented. Hence there arose a style combining all the beauty and finish of the previous native art with a certain magnificence of conception which is deficient in their own works. The elevations of the mosques have usually been studiously arranged with a view to express at once the structural arrangements, and to avoid monotony of outline by the varied elevation of each division. The central portion of the façade was raised by a storey over the roof of the wings, and to the front of this was attached the minarets, in the earliest mosques forming only small turrets over the façade, but soon after they became richly carved towers of considerable height. The upper storey formed a gallery under the central dome which was supported on pillars connected by open stone trellis work, admitting a subdued light, and providing perfect ventilation (see Plate III. fig. 15). At first the façades were pierced by arched entrances, but at a later date a screen of columns formed an open front and the minarets were removed to the corners, no longer for the _mu'azzin_, but simply as architectural ornaments. The tombs were pillared pavilions of varying dimensions, the central area over the grave covered by a dome standing on twelve pillars. These pillars connected by screens of stone trellis work carved in ever-varying patterns, and round this there might be a verandah with twenty pillars in the periphery, or a double aisle with thirty-two in the outer square. And as these were irregularly spaced in order to allow the inner twelve to support the lintels of a regular octagon for the dome, the monotony of equal spacing was avoided. For further details and examples of this style, however, we must refer the reader to the published volumes of the archaeological survey of Western India relating to Ahmedabad and Gujarat.
