Higgins is of the opinion that Stonehenge is the work of the same era with the caves of India, the pyramids of Egypt, and the stupendous monument at Carnac--a structure which, it is claimed, must have required for its construction an amount of labor equal to that of the pyramids. Undoubtedly there has never been a religious shrine which has excited more curiosity than has Abury, of which, unfortunately, nothing now remains, although in the early part of the eighteenth century enough had been preserved to prove the identity of its signification with other ancient religious monuments both in the British Isles and in the countries of the East. Perhaps there is no way by which this shrine can be better understood than by quoting the exact language of those who have written upon the subject. Especially is this true concerning the testimony of those who, after personal investigation, have given to the public the results of their research. In the History of Wiltshisre, published by Sir R. Colt Hoare, Bart., appears the following from Dr. Stukeley: "The situation of Abury is finely chosen for the purpose it was destined to, being the more elevated part of a plain, from whence there is almost an imperceptible descent every way. But as the religious work in Abury, though great in itself, is but a part of the whole (the avenues stretching above a mile from it each way), the situation of the whole design is projected with great judgment, in a kind of large, separate plain, four or five miles in diameter. Into this you descend on all sides from higher ground. The whole Temple of Abury may be considered as a picture, and it really is so. Therefore the founders wisely contrived that a spectator have an advantageous prospect of it as he appeared within view. When I frequented this place, which I did for some years together, to take an exact account of it, staying a fortnight at a time, I found out the entire work by degrees. The second time I was here, an avenue was a new amusement; the third year another. So that at length I discovered the mystery of it, properly speaking, which was, that the whole figure represented a snake transmitted through a circle. This is an hieroglyphic or symbol of highest note and antiquity.
