Temples, or stone circles corresponding to temples, might face either to the north-east or south-east, for the Summer or Winter Solstice, marking the end of the sun's journey, or they might be directed towards the east, when the sun would appear in the appointed spot twice in the year; once in his journey southward, and once on his return; in other words, at the two Equinoxes. Stonehenge is so arranged as to mark the sun at its Summer Solstice.
But, interesting as these speculations of the Sun Temple theory may be, the facts recorded by Sir Norman Lockyer in 1901 are even more so, as by independent calculations he has arrived at the same date for Stonehenge as the archæologist. Briefly his task was to calculate the extent of the change in the obliquity of the ecliptic since the building of Stonehenge. The whole process involves a certain knowledge of astronomical operations and calculations, and the reader is referred to Sir Norman Lockyer's book for the actual steps taken to arrive at his conclusion. But on astronomical grounds pure and simple he was able to fix the date of Stonehenge as "lying between 1900-1500 B.C."
It is at all events interesting that his results should tally with those of Mr. Gowland who, working on entirely different lines, came to practically the same conclusion.
Having proceeded thus far it is well, however, not to insist too strongly on the "Sun Temple" theory, on the lines already sketched out. It should be always remembered that the "Hele Stone" is an unworked stone, which stands without the circle, and does not form a symmetrical integer in the structure. Being unwrought it may have been erected at an earlier date, and might belong to an earlier culture. It is possible that Stonehenge may have been a later addition to the Hele Stone. Many of the arguments relating to the "wise men" and the observation of sunrise are matters of analogy rather than direct proof, and though coincidences are ever suggestive and fascinating, they cannot always be entirely accepted as proof. While it is quite possible that the Hele Stone was erected to mark the Solstice and to afford a definite means of determining the year, this may not justify the theory that the entire structure was an astronomical observatory and dedicated entirely to sun worship, with elaborate ramifications, and "observation" mounds for celestial phenomena. Weighing, therefore, the archæologist's and astronomer's evidence, it is fairly safe to conclude that Stonehenge can be dated at about B.C. 1700, and that its use was religious; probably a temple, in which the sun may have been adored in some way. As yet, however, the actual nature of that worship is a matter for speculation. It is of the utmost importance in dealing with a question like this, to observe the greatest caution and to maintain a strictly detached position. The astronomer, archæologist, geologist, and anthropologist have each their share in the solution of the problem, but each also has the bias due to his own special science. The mineralogist solves the problem of the Foreign Stones by suggesting a "glacial drift" without reference to the geologist, who will tell him that the local gravels contain no pebbles which belong to those classes of stones known as Foreign Stones. The astronomer, in his quest for alignments, will convert barrows into observation mounds, without reference to their uses and contents, and without allowing for the ignorance of the period, while the anthropologist often allows his imagination to carry him beyond the limits of actual fact. Time, and constant careful investigation, will pierce some of the mists which must always shroud the origin of Stonehenge, but the true solution will be for the field archæologist, rather than to the weaver of theories or the student in his library.
The circular form, the horseshoe form, the unhewn Hele Stone, all bespeak religious origin. These are actual, visual facts, as is the sunrise on the Solstice. Around these arises a clamour of conflicting claims, each possibly containing much of real importance, each probably expressing some clue to guide the future worker on his way, but none containing that element of finality which is once and for all time to quell the storm of controversy which has ever raged about this ancient monument of the plain.
THE DRUID QUESTION[ToC]
Perhaps one of the most persistent traditions which has been passed on from generation to generation is that which connects Stonehenge with the Druids. There is, indeed, a vast literature on the subject of Druidism, but the actual knowledge of the subject is limited, and the entire question is very obscure. Much of the information existing is derived from a time when Christianity had long been established. The early Celtic religion has in fact been overlaid and embellished by so many later theories as to be particularly confusing to the modern student. Benedictine historians have discovered in Druidism traces of revealed religion by the simple process of confusing similarity with identity. The Gaul adored the oak tree, therefore this must have been a far-off remembrance of the plains of Mamre.
