When Mr. Fergusson commenced the study of Indian Architecture, nothing was really known on the subject. He had first to collect the materials, and after years of work he was able at last to leave the Architecture of India in a classified form. This was in itself a great achievement for one man to do. But he did more than this. He traced back the developments of form and construction in many cases to their early beginnings, and thus gave us their origin. It is only when this has been accomplished that we can truly say “we know” any particular style of architecture. We have still some very interesting problems of this kind to work out in regard to India; and suggestions regarding them, even although they should ultimately be found to have pointed in the wrong direction, may yet be useful in many ways; such speculations may call the attention of men in India to the information that is required, and by this means we have the chance of receiving knowledge. I have often discussed some of these questions of origin with Mr. Fergusson, and he used to refer to some of the unexplored parts of India, where he thought some remains of the older forms of Architecture might yet be found, which would throw light on what we wanted. His mode of expressing himself was, “If some man, with the necessary knowledge, and with an eye in his head, could be sent,” he felt certain that there are old temples in many parts not yet discovered that would clear up most of the doubtful points.
