3. Cromlechs (Celtic = "stone circle"). Circles enclosing barrows or dolmens.
Stonehenge is a highly specialised example of this last class. Round these cromlechs popular myth and superstition have crystallised themselves into tales of the devil and his works (as in the case of Stonehenge), ogres, giants, dwarfs, Sabbath breakers, and infidels, turned to stone. In nearly every case there is some story of the supernatural, which cannot be accidental, but which must have its root in past religious observance.
It is a recognised fact that the worship of stones is more widely distributed than any other primitive cult. Its almost universal distribution can be referred to the tendency of the half savage mind to confuse persons and things, and from seeming likeness of the inanimate to the animate, to endue the lifeless object with the virtue and power of the living object. This mental outlook is better understood in practice than in theory. A Melanesian native may come across a large stone, lying upon the top of a number of smaller stones. It suggests to him a sow with her litter of pigs, and he at once makes an offering to it, in the hope that he will secure pigs. In determining the function of Stonehenge, therefore, it will be useful to compare it with similar existing stone circles. The largest of these in this country is Avebury, not many miles distant from Stonehenge. Unluckily, to-day it is so ruined that its former greatness is hardly to be distinguished by the unskilled observer. Formerly comprising some hundreds of unhewn Sarsen stones, barely a score remain in position at the present day. In Avebury, as it was, can be found the early typic model of which Stonehenge is the final product. The use of the circle as a basic form is common to both. In Avebury the Sarsen is a rough unhewn monolith; in Stonehenge it is squared, dressed, and crowned with its lintel. All evidences of a slow evolution from Neolithic to Bronze culture. But whereas the circle alone is used at Avebury, Stonehenge has in addition the horseshoe series of Trilithons and foreign uprights, and in this particular differs from all other Cromlechs in this country. It is the climax of the Megalithic monument, and its use very certainly must have been connected with the religion of the race which set it up. It was, in short, a religious structure, probably used for the observation of the sun, and possibly connected with "nature worship."
The fact that the sun rises over the Hele Stone on the Summer Solstice, and that it can be observed in direct alignment with the centre of the Great Trilithon, can hardly be due to accident. Chance might bring two stones into such a position on the Solstice, but, in this case, the entire monument is so arranged as to place the rising sun in a due line with its axis on this particular day.
It will be well to consider the facts which must have been within the knowledge of the builders of Stonehenge, and to trace as far as may be their reasoning in the building of it.
To begin with, it is almost certain that at the time of building, there existed some primitive form of priesthood, or body of "wise men." This is quite compatible with the culture of the period. The existence of the Neolithic Long Barrows is sufficient evidence that man had, by this time, arrived at that particular culture which grasps the existence of a "spirit."
Death only terminated the existence of the body, and not that of the spirit. It was even able to return and enter another body, say that of a new-born infant, an animal, or tree. And being after the manner of human beings, spirits could understand human language and become accessible to human petitions. Thus a spirit might even prove a powerful friend or enemy. And the dwellings of these spirits would be those great powers which meant so much to a primitive people; the sun, moon, stars, rivers, forests, and clouds; from which arose the two great classes of spirit, the "ancestral" and the "spirit of nature." From this general body was developed a regular hierarchy of good and evil spirits, gradually ascending to the conception of one great creative spirit, or superior deity.

To these early men, therefore, there was always the problem of maintaining diplomatic relations with the unseen forces about them, and for this purpose a primitive priesthood became necessary. The chieftain would manage the temporal affairs of the tribe, those spiritual would be relegated to a special body of wise men, or intermediaries. These men would certainly, from the nature of their calling, be not so much men of action as men of learning, the recorders of history and tradition, students of the natural phenomena, and of all those signs and portents which concerned the good of the community. One of the earliest facts which impressed itself upon them must have been the horizon. It was above that horizon that the sun rose in the morning, and below that horizon that it sank to rest at night; further, when the sun had set the moon and stars peeped up from that line, and sank below it, all in due course. These were facts easily apprehended. The common people even had grasped them, but the wise men learned more. As the link between man and the spirits of the stars, sun, and moon, they came to recognise that the sun did not rise over the same spot on the horizon every day. In the summer it rose roughly in the north-east and set in the north-west. In the winter, on the other hand, it rose in the south-east and set in the south-west. Moreover, these variations would be found to be regular and recurring. The sun would appear to move every day after the Solstice towards the east, and from the east towards the south, back again towards the east, and once more northwards. A staff set in the ground would determine the range of the sun's apparent journey and its extreme limits or turning points. This would fix the Summer Solstice in the north-east, and the winter Solstice in the south-east. Even such simple learning as this was probably beyond the capacity of the tribesman, whose daily duties took him afield early and late. But it was to his interest that all such observations should be entrusted to individuals who could keep definite count, and know exactly at what part of the horizon the sun might be expected to appear. In this way the solar year might be mapped out and divided into Solstices and Equinoxes. Nor was this a mere arbitrary arrangement. The good of the community depended upon it. The agriculturalist depended upon the sun for his crops. It was essential that he should know the correct time to plough, to sow, and to reap. Without the aid of the "wise men" he had no means of knowing what day it was, or how much longer he could count upon the sun for his primitive agriculture. The "wise man," on his side, realised the importance of his knowledge, and doubtless used it to his own advantage, thus winning support and respect from his simple followers.
