Sources.- From J. F. Campbell's manuscript collection now deposited at the Advocates' Library in Edinburgh (MS. 53, vol. xi.). Collected in Gaelic, February 14, 1862, by Hector MacLean, from Roderick MacNeill, in the island of Menglay : MacNeill learnt the story about 1840 from a Barra man. I have omitted one visit of the Black Horse to Greece, but otherwise left the tale untouched. Mr. Nutt gave a short abstract of the story in his report on the Campbell MSS. in Folk-lore, i. 370.

Parallels.- Campbell gives the following parallels in his notes on the tale, which I quote verbatim. On the throwing into the well he remarks: "So this incident of' Lady Audley's Secret' was in the mind of a Barra peasant about 1840. Part of a modern novel may be as old as Aryan mythology, which was one point to be proved." [The incident of throwing into the well almost invariably forms a part of the tales of the White Cat type.] With regard to the Black Horse, Campbell notes that a Gaelic riddle makes a Black Horse identical with the West Wind, and adds "It is for consideration whether this Horse throws light on the sacred Wheel in Indian Sculptures it is to be noted that a Black Horse is the sacrificial colour."

"The Cup is a well-known myth about winning a Fairy Cup which pervades Scandinavian England in many forms." "A silver ring, two quaint serpents heads pointing opposite ways, is a common Scandinavian wedding-ring many were to be got in Barra and elsewhere in 1869, sold by emigrants bound for America."

"Those who can account for myths must settle the geography of the Snow Mountain. Avalanches and glaciers are In Iceland, in the Caucasus, and in Central Asia. There are none within sight of Menglay. Hindoo cosmogony, which makes the world consist of seven rings, separated by seas and by a wall of mountains, may account for this in some sort."

On the spikes driven into the Horse, Campbell compares the Norse story of " Dapple-grim" and the Horse sacrifice of the Mahabharata. On the building of the Magic Castle, Campbell remarks : "Twashtri was the Carpenter of the Vedic gods : can this be his work?" On the Horse's head being struck off Campbell comments: "This was the last act in the Aryan Horse's sacrifice, and the first step in the Horse apotheosis."

Remarks .- Campbell has the following note at the end of the tale, from which it would seem that in 1870 at least he was very nearly being an Indiamaniac.

"So ends this horse-riding story. Taking it as it is, with the test of language added, nothing short of an Asian origin will account for it. A Gaelic riddle makes 'a black horse' mean the invisible wind, and a theorist might suppose this horse to be the air personified. As Greece is mentioned, he might be Pegasus, who had to do with wells. But he had wings, and he was white, and there is nothing in classical fable like this Atlantic myth.

'The enchanted horse' of Arabian Nights was a flying machine, and his adventures are quite different. This is not the horse of Chaucer's Squire's Tale. He is more like 'Hrimfaxi,' the horse of the Edda, who drew the car of Nstt in heaven, and was ridden round the earth in twelve hours, followed by Dagr and his glittering horse Skinfaxi. The black horse who always arrives at sunrise is like the horse of night, but there is no equivalent story in the Edda. 'Dapple-grim' in Norse tales is clad in a spiked bull's hide, and is mixed up with a blazing tar-barrel, but his adventures won't fit, and he was grey.

"The story is but an imperfect skeleton. The cup was to give strength; he had to open seven gates after he got the cup, but it does nothing. The hood is to hide with; he went in and out of the palace unseen after he had got the hood, but it plays no part. The light shoes were the shoes of swiftness of course, but they never showed their paces. Baldr's horse was led to the funeral pile with all his gear; and Odin laid the gold ring Draupnir on the pile. Such rites might account for the ring in the blazing lake. Hermothr's ride northwards and downwards to the abode of Hel to seek Baldr, his leap over the grate, and his return with the ring (Edda 25), might account for one adventure.

"The many-coloured horses of the sun in the Indian mythology and solar myths may account for all these horses, astronomically or meteorologically. The old Aryan Aswa Medha or sacrifice of a black horse, and the twelve adventures of Arjuna as told in the Mahabbarata, are something like this story in some general vague way. But the simplest explanation of this Menglay myth, fished out of the Atlantic, is to admit that 'the black horse' and all this mythical breed came west with men who rode from the land where horses were tamed, which is unknown."
