Stone circles have given rise to much discussion. They are perhaps best known by their popular name of Druidical temples. Whatever were the other purposes served by them, there is hardly any doubt that they were primarily associated with interments. Dr. Joseph Anderson has pointed out that a certain archæological succession can be traced. Thus we find first, burial cairns minus stones round them, then cairns plus stones, and finally, stones minus cairns. At one time there was a widely-spread belief that men could be transformed into standing stones by the aid of magic. This power was attributed to the Druids. There are also traditions of saints thus settling their heathen opponents. When speaking of the island of Lewis, Martin says, "Several other stones are to be seen here in remote places, and some of them standing on one end. Some of the ignorant vulgar say that they were men by enchantment turned into stones. Such monoliths are still known to the Gaelic-speaking inhabitants of Lewis as Fir Chreig, i.e., false men. We learn from the "New Statistical Account of Scotland" that the two standing stones at West Skeld, in Shetland, were believed by the islanders to have been originally wizards or giants. Close to the roadside on Maughold Head, in the Isle of Man, stands an ancient runic cross. A local tradition states that the cross was once an old woman, who, when carrying a bundle of wool, cursed the wind for hindering her on her journey, and was petrified in consequence. With superstitions thus clinging to standing-stones it is not to be wondered that springs in their neighbourhood should have been regarded with special reverence. In the "Old Statistical Account of Scotland" allusion is made to Tobir-Chalaich, i.e., Old Wife's Well, situated near a stone circle in the parish of Keith, Banffshire, and to another well not far from a second circle in the same parish. The latter spring ceased to be visited about the middle of last century. Till then offerings were left at it by persons seeking its aid. The writer of the article on the island of Barry, Inverness-shire, in the same work, says, "Here, i.e., at Castle-Bay, there are several Druidical temples. Near one of these is a well which must have been once famous for its medicinal quality, as also for curing and preventing the effects of fascination. It is called Tobbar-nam-buadh or the Well of Virtues." Under the heading "Beltane," in "Jamieson's Scottish Dictionary," the following occurs:--"A town in Perthshire, on the borders of the Highlands, is called Tillie (or Tullie) Beltane, i.e., the eminence or rising ground of the fire of Baal. In the neighbourhood is a Druidical temple of eight upright stones, where it is supposed the fire was kindled. At some distance from this, is another temple of the same kind, but smaller, and near it a well still held in great veneration. On Beltane morning, superstitious people go to this well and drink of it, then they make
