But the man who brought this new astronomical knowledge was, before he came, astrologer and magician as well, and, further, he was a priest; hence on account of his knowledge of the seasons, he could not only help the aboriginal tiller of the soil as he had never been helped before, by his knowledge; but he could appeal in the strongest way to his superstitious fears and feelings, by his function as the chief sacrificer and guardian of the sacrificial altars and fires. Hence it was that everything relating to the three different classes of things to which I have referred was regarded as very holy because they were closely associated with the astronomer-priests, on whom the early peoples depended for guidance in all things, not only of economic, but of religious, medical and superstitious value. The perforated stones were regarded as sacred, so that passing through them was supposed to cure disease. Whether men and women, or children only, passed through the hole depended upon its size. But a hole large enough for a head to be inserted was good for head complaints. The wells, rivers, and lakes used by the priests were, as holy places, also invested with curative properties, and offerings of garments (skins?), and pins to fasten them on, as well as bread and wine and cheese, were made at these places to the priests. The fact that the tree on which the garment was hung was either a rowan or a thorn shows that these offerings commenced as early as the May-November worship. The holed stones, besides being curative, were in long after years, when marriage had been instituted, used for the interchange of marriage vows by clasping hands through the opening. The cups for the light would also be sacred objects; and many of them have been since used for holy water. The cursus at Stonehenge and the avenues on Dartmoor may be regarded as evidences that sacred processions formed part of the ceremonial on the holy days, but sacrifices and sacred ceremonials were not alone in question; many authors have told us that feasts, games and races were not forgotten. This, so far as racing is concerned, is proved, I think, by the facts that the cursus at Stonehenge is 10,000 feet long and 350 feet broad, that it occupies a valley between two hills, thus permitting of the presence of thousands of spectators, and that our horses are still decked in gaudy trappings on May Day.
