The excavations conducted by General Cunningham, at the same place, are hardly more satisfactory in their result. The two buildings he explored seem to bear the relation to one another of a vihara 60 ft. square over all, and a temple of little more than half these dimensions with a projecting porch on each face.[168] Only the foundation of these buildings now remains, and nothing to indicate how they were originally finished. We may eventually hit on some representation which may enable us to form definite ideas on this subject, but till we do this we probably must be content with the interiors as seen in the rock-cut examples. BENGAL CAVES. None of the Behar caves can, properly speaking, be called viharas, in the sense in which the word is generally used, except perhaps the Son Bhandar, which, as before mentioned, General Cunningham identifies with the Sattapanni cave, in front of which the first convocation was held 543 B.C. It is a plain rectangular excavation, 33 ft. 9 in. long by 17 ft. wide, and 11 ft. 7 in. to the springing of the curved roof.[169] It has one door and one window, but both, like the rest of the cave, without mouldings or any architectural features that would assist in determining its age. The jambs of the doorway slope slightly inwards, but not sufficiently to give an idea of great antiquity. In front there was a wooden verandah, the mortice holes for which are still visible in the front wall. The other caves, at Barabar and Nagárjuna, if not exactly chaityas in the sense in which that term is applied to the western caves, were at least oratories, places of prayer and worship, rather than residences. One Arhat or ascetic may have resided in them, but for the purpose of performing the necessary services. There are no separate cells in them, nor any division that can be considered as separating the ceremonial from the domestic uses of the cave, and they must consequently, for the present at least, be classed as chaityas rather than viharas. The case is widely different when we turn to the caves in Orissa, which are among the most interesting, though at the same time the most anomalous, of all the caves in India. They are situated in two isolated hills of sandstone rock, about twenty miles from Cuttack and five from Bhuvaneswar. The oldest are in the hill called Udayagiri; the more modern in that portion designated Khandagiri. They became Jaina about the 10th or 11th century, and the last-named hill is crowned by a Jaina temple, erected by the Maharattas in the end of the last century.
