mother made him a dress of the deer's hide. Afterwards he slew his foster-brother for laughing at him, caught a wild horse, and came to his father's brother's palace. He had never been called other than "Great fool," and when asked his name by his cousin, playing shinty, answered, "Great Fool." His cousin mocked at him, and was forthwith slain. On going into the King's (his uncle's) presence, he answered in the same way. His uncle recognised him, and reproaching himself for his folly in not having slain the mother with the father, went with him, as did all the people.
In my article on the Aryan Expulsion and Return Formula among the Celts ("Folk-Lore Record," vol. iv.), I have shown that this tale is widely distributed in the Celtic Heldensage as well as in the Celtic folk-tale. Before noticing the variants, a word of explanation may be necessary. The term, Arische Aussetzungs-und Rückkehr-Formel, was first employed by J. G. v. Hahn in his Sagwissenschaftliche Studien (Jena, 1876), to describe a tale which figured in the heroic literature of every Aryan race known to him. He examined fourteen stories, seven belonging to the Hellenic mythology, Perseus, Herakles, Oedipus, Amphion and Zethos, Pelias and Neleus, Leukastos and Parrhasius, Theseus; one to Roman mythic history, Romulus and Remus; two to the Teutonic Heldensage, Wittich-Siegfried, Wolfdietrich; two to Iranian mythic history, Cyrus, Key Chosrew; two to the Hindu mythology, Karna, Krishna. I was able to recover from Celtic literature eight well-defined variants, belonging to the Fenian and Ultonian cycles of Irish Heldensage (heroes, Fionn and Cu-Chulaind); to Irish mythic history, Labraidh Maen; to the folk-tale still living in the Highlands, Conall and the Great Fool; to the Kymric Heldensage, Peredur-Perceval, Arthur, and Taliesin. An examination of all these tales resulted in the establishing of the following standard formula, to the entirety of which it will of course be understood none of the tales answer:—
| I. | I. Hero born— |
| (a) | Out of wedlock. |
| (b) | Posthumously. |
| (c) | Supernaturally. |
| (d) | One of twins. |
