In the year 1777 a shaft was sunk from the top of the mound to the base, by order of the then Duke of Northumberland and Colonel Drax, but no record has been preserved of what they found, or rather did not find, for had they made any discovery of the least importance, it certainly would have been communicated to some of the learned societies of the day. Subsequently, in 1849, a shaft was driven nearly horizontally from the southern face on the level of the original soil to the centre, where it met the Duke's shaft; and subsequently a circular gallery was carried round the centre, but in vain; nothing was found in these excavations that would show that the mound had ever been used for sepulchral purposes, or that threw any light whatever on its history or destination.[93]
Judging from the analogies gathered from our knowledge of the parallel Indian series, we ought not to be surprised if this really were the only result. From the accounts of the Chinese travellers who visited India in the fifth and seventh centuries, we learn that about one-half of the topes they saw and described were erected to commemorate events, and not to contain relics, or as simulated tombs. Wherever Buddha or any of his followers performed any miracles, or where any event happened of sufficient importance to make it desirable that the memory of the locality where it happened should be preserved, there a Tope was erected. To take an example as bearing more directly than usual on our present subject. When Dutthagamini, king of Ceylon (161 B.C.), defeated the usurper Ellala, and restored the true faith, "he erected near the capital a dagoba in commemoration of his victory. A stone pillar marks the spot where the action commenced, and another stone pillar exists there with an inscription to the effect that it marks the spot rendered sacred by the death and blood of Ellala."[94] The dagoba is a simple mound of earth, and, so far as known, has never been opened. In Afghanistan, many of the topes opened by Messrs. Masson and Honigberger were found to be what they call "blind topes," but they were not able to detect by any external sign whether their researches were likely to be rewarded with success or to end in disappointment.[95]
Whether these analogies are worth anything or not, nothing appears, at first sight at least, more probable than that, if the fallen chiefs of a victorious army are buried at Avebury, the survivors should have employed their prisoners as slaves to erect a mound on the spot probably where the chiefs were slain and the battle decided. The tradition, however, having been lost, the mound stands silent and uncommunicative, and it is not easy now to read its riddle.
It is very premature, however, to speculate either on these analogies or on the negative results of the explorations made into the hill: these last were undertaken, like the diggings at Avebury, on the empirical assumption that the principal deposit would be found in the centre, and at Silbury on the ground level, which is exactly the place where almost certainly it was not. Supposing that there is a low-level sepulture at Silbury, it probably will be found within 30 or 40 yards of the outer face of the mound, on the side looking towards Avebury, if it is connected with that monument. But the knowledge we have acquired, as will be afterwards detailed, from the examination of the Minning Lowe, Arbor Lowe, Rose Hill tumuli, and other monuments of this class, would lead us to expect to find the principal deposit near the summit. The bit of a bridle ([woodcut No. 18]) and the traces of armour which were found in Stukeley's time, near the summit, mark in all probability the position of the principal graves, and nothing would surprise me less than if five or six entombments were found arranged around the upper plateau at a small depth below the surface. We shall be in a better position to judge how far this is probable when we have finished this chapter; but till the evidence is adduced, it is useless to speculate on its effect.
18. Iron Bit of Bridle. Found in Silbury Hill.
At one time I hoped that the Roman road might be found to have passed under the hill, and if this were the case, it would settle the question as to whether it were pre- or post-Roman. In order to ascertain this, some excavations were made into the hill in 1867, and simultaneously on the high ground to the southward of it. As traces which seemed undoubtedly to mark the existence of the road running past the hill, at about 50 to 100 yards to the southward, were found there, the excavations into the hill were discontinued, and the line of the road considered as established. Owing to various mishaps, no plan of these discoveries has yet been published, but the annexed woodcut, which is traced from the Ordnance Survey sheet, will suffice to explain its bearing on the question.
