It is, of course, difficult for those who have never seen a building of the class just described to judge of the effect of these arrangements; and they have seldom been practised in Europe. There is, however, one building in which they have accidentally been employed to a considerable extent, and which owes its whole beauty to the manner in which it follows the arrangement above described. That building is Sir Christopher Wren’s church of St. Stephen’s, Walbrook. Internally its principal feature is a dome supported on eight pillars, with four more in the angles, and two principal aisles crossing the building at right angles, with smaller square compartments on each side. This church is the great architect’s masterpiece, but it would have been greatly improved had its resemblance to a Hindu porch been more complete. The necessity of confining the dome and aisles within four walls greatly injures the effect as compared with the Indian examples. Even the Indian plan of roofing, explained above, might be used in such a building with much less expense and less constructive danger than a Gothic vault of the same extent. PLANS. Up to the present time only one temple has been discovered in India which gives us even a hint of how the plans of the Buddhist Chaitya Halls became converted into those of the Jaina and Hindu temples. Fortunately, however, its evidence is so distinct that there can be very little doubt about the matter. The temple in question is situated in the village of Aiwulli, in Dharwar, in western India, not far from the place where the original capital of the Chalukyan sovereigns is supposed to have been situated, and near the caves of Badami on the one hand and the temples of Pittadkul on the other. Its date is ascertained by an inscription on its outer gateway, containing the name of Vicramaditya Chalukya, whom we know from inscriptions certainly died in A.D. 680, and with less certainty that he commenced to reign A.D. 650.[255] The temple itself may possibly be a little older, but the latter may fairly be taken as a medium date representing its age. It is thus not only the oldest structural temple known to exist in western India, but in fact the only one yet discovered that can with certainty be said to have been erected before the great cataclysm of the beginning of the 8th century.
