One other stone is deserving of some note, from the vague records which tradition has preserved of its connexion with the rites of a long extinct creed. Mr. Wakeman remarks, in his Archæologia Hibernica,[121] "Perforated stones, very similar to the ordinary pillar stone, are found in many parts of Ireland, Scotland, and even, as appears from Mr. Wilford's Asiatic Researches, in India. Abroad as well as at home their origin is shrouded in the deepest obscurity, nor is it likely that the subject can ever be elucidated." They are by no means so common, however, as this would imply. At Applecross, in the west of Ross-shire, a perforated stone occupies the centre of a stone circle; and at Tormore, in the parish of Kilmorie, Buteshire, there is a celebrated monolithic circle, styled _Siudhe choir Fhionn_, or Fingal's cauldron seat, one of the columns of which is perforated, and is commemorated in old Highland traditions as the stone to which the Celtic hero was wont to tie his dog Bran. Immediately adjoining the circle are three huge unhewn columns, about fifteen feet in height above the surface of the moor. Along with these examples may be noted a curious group in the parish of Maddern, Cornwall, consisting of three stones, the centre one of which is pierced with a large circular hole, through which, Borlase informs us,[122] rheumatic patients were wont to crawl as a sovereign remedy for their disease. Perforated stones must once have been common in England, and probably in Scotland also, as the Anglo-Saxon laws repeatedly denounce similar superstitious practices; but they are now of the rarest occurrence. Tradition has preserved some curious associations with one of the most interesting Scottish examples, which may perhaps be thought to throw some doubtful light on the use to which such perforated pillars were devoted at a comparatively late period of our island history. The celebrated STONE OF ODIN, near the Loch of Stennis, in Orkney, which has had a new interest added to it by being interwoven with the romantic incidents of the "Pirate," was one of the remarkable monolithic group called The Stones of Stennis. It formed no part, however, either of the Great Ring of Brogar, or of the neighbouring circle of Stennis, but stood apart, to the north-east of the latter group; though it can scarcely be doubted that it bore some important relation to these ancient and mysterious structures. The Stone of Odin is described as standing about eight feet high, and perforated with an oval hole large enough to admit a man's head. A curious, though rudely executed bird's-eye view of the Stones of Stennis is given in the Archæologia Scotica,[123] from a drawing executed by the Rev. Dr. Henry, about the year 1780, and there a man and woman are seen interchanging vows, plighted by the promise of Odin, which Sir Walter Scott refers to as "the most sacred of northern rites yet practised among us." The vow was sworn while the
