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.

What we know of the age of the older caves is principally derived from a long inscription on the front of the oldest, known as the Hathi Gumpha, or Elephant Cave.[170] From it we learn that it was engraved by a king called Aira, who ascended the throne of Kalinga in his twenty-fourth year, and spread his power by conquest over neighbouring rajas. He seems at first to have vacillated between the Brahmanical and Buddhist faiths, but finally to have adopted the latter and distributed infinite alms. Among other good works, he is said “to have constructed subterranean chambers—caves containing a chaitya temple, and pillars.”

Palæographically, the forms of the letters used in this inscription are identical with those used by Asoka in the copy of his edicts on the Aswatama rock close by, and that recently found at Aska, near the northern corner of the Chilkya lake. The first presumption, therefore, is that they may be of about the same date. This is justified by the mention of Nanda in the past tense, while there seems no reason for doubting that he was one of the kings of that name who immediately preceded the revolution that placed Chandragupta on the throne. Beside these, there are other indications in this inscription which seem to make it almost certain that Aira was contemporary with the great Mauryan dynasty of Magadha; but whether he preceded or followed Asoka is not quite so clear. Still it appears unlikely that Asoka would have been allowed to set up two copies of his edicts in the dominions of such powerful kings as Aira and his father seem to have been, and as unlikely that Aira should make such a record without some allusion to the previously promulgated edicts, had they then existed. On the whole, I am inclined to believe that Aira lived before Asoka, and, if so, that this is the oldest inscription yet found in India. Be this as it may, the cave in which it is found is certainly the oldest here. It is a great natural cavern, the brow of which has been smoothed to admit of this inscription, but all the rest remains nearly in a state of nature. Close to it is a small cave, the whole “fronton” of which over the doorway is occupied by a great three-headed Naga, and may be as old as the Hathi cave. The inscription on it merely says that it is the unequalled chamber of Chulakarma, who seems also to have excavated another cave, here called the Pawan Gabha,[171] or Purification Cave.

Besides these, and smaller caves to be noticed hereafter, the great interest of the Udayagiri caves centres in two—the so-called Ganesa cave, and that called the Raj Rani, or Rani Hanspur, from a tradition—Hindu—that it was excavated by the Rani of Lelat Indra Kesari, the celebrated builder of the Bhuvaneswar temple in the 7th century.

70. Ganesa Cave.
(From a Plan by Mr. Locke.) Scale 50 ft. to 1 in.

The former is a small cave, consisting of two cells, together 30 ft. long by 10 ft. wide, in front of which is a verandah, slightly longer, that was once adorned with five pillars, though only three are now standing ([Woodcut No. 70]). There is an inscription on this cave in the Kutila characters, dedicating it to Jaganath; but this is evidently an addition in modern times.[172] The style of the architecture may be judged of from the annexed woodcut, representing one of its pillars ([Woodcut No. 71]). They are of extreme simplicity, being square piers, changing into octagons in the centre only, and with a slight bracket of very wooden construction on each face. The doorways leading into the cells are adorned with the usual horseshoe formed canopies copied from the fronts of the chaitya halls, and which we are now so familiar with from the Bharhut sculptures, and from the openings common to all wooden buildings of that age.
