The three principal examples in the county are Arbor Low, the Bull Ring, and the Wet-Withens. Arbor Low is situate on the hillside, 1,200 feet above the sea, a mile to the east of Parsley Hay Station, eight miles south-east from Buxton. It has been termed the Stonehenge of the Midlands, and as a megalithic monument, the very grandeur of its loneliness appeals to memories of the days of old and the race that is gone. Its dimensions have already been given, but its general features are a circular plateau, averaging about one hundred and sixty feet in diameter, and surrounded by a broad fosse, enclosed, save at the two entrances, within a high vallum of earth. In the centre of the plateau are three limestone blocks, of which one is fourteen feet in length, and another, now broken, about twelve feet by eight feet six inches; these, before destruction, probably formed a dolmen, or trilithon, similar to those of Stonehenge. Arranged around the edge of the plateau, and seemingly in pairs, which also allows the possibility of a trilithic formation, are forty-six similar stones, all, with one exception, lying prone, and measuring from thirteen feet by six to comparatively small dimensions—the exception referred to, however, lies at a very low angle. They seem to have been selected from the _surface_ limestone of the district, which explains the many weathered and holed stones amongst them; and it must be remembered that a holed stone has always claimed a superstitious veneration. It is present in the circle at Stennis, in our chambered barrows, and in the dolmens of France, Russia, and India. The trilithons of Stonehenge may be its elaboration, and in later times King Alfred caused the Danes to swear their treaty according to their most solemn custom upon the holy ring. Even in mediæval days the superstition connected with St. Wilfred’s Needle at Ripon may probably have been but a survival of this archaic tradition.
