engaging parties joined hands through the perforation in the stone; and though it is difficult to decide how much of the tradition may be ascribable to modern embellishment and the adaptation of a genuine heirloom of primitive superstition to the preconceived theories of local antiquaries, there cannot be a doubt of the popular sacredness attached to this sacramental stone in former times. An illustration of the practice from which this originated is supposed to be traceable in an ancient Norse custom, described in the Eyrbiggia Saga, by which, when an oath was imposed, he by whom it was pledged passed his hand, while pronouncing it, through a massive silver ring sacred to this ceremony.[124] The solemnity attached to a vow ratified by so awful a pledge as this appeal to the Father of the Slain, the severe and terrible Odin, continued to maintain its influence on the mind till a comparatively recent date. Dr. Henry, writing in 1784, refers to the custom as having fallen into disuse within twenty or thirty years of the time he wrote, and adds, "this ceremony was held so very sacred in those times, that the person who dared to break the engagement was counted infamous, and excluded all society." Principal Gordon, of the Scots College, Paris, who visited Orkney in 1781, thus refers to a curious example, showing probably the latest traces of this venerable traditionary relic of Scandinavian superstition:[125] "At some distance from the semicircle stands a stone by itself, eight feet high, three broad, nine inches thick, with a round hole on the side next the lake. The original design of this hole was unknown, till about twenty years ago it was discovered by the following circumstance: A young man had seduced a girl under promise of marriage, and she proving with child, was deserted by him. The young man was called before the Session; the elders were particularly severe. Being asked by the minister the cause of so much rigour, they answered, You do not know what a bad man this is; he has broke the promise of Odin. Being further asked what they meant by the promise of Odin, they put him in mind of the stone at Stenhouse, with the round hole in it, and added, that it was customary when promises were made, for the contracting parties to join hands through this hole; and promises so made were called the promises of Odin."[126]
