The uncanny character thus attributed to a stranger includes not merely the possession of magical powers. In a society where everyone, or at least a large and unknown number of persons, is believed to be endowed more or less with magical powers, this is a matter of course. But a halo of still more mysterious possibility encircles a stranger: he may be a superhuman Power, a dead man, or even a god. Hence arise the numerous stories, many of which have been collected by Mr Gerould in his monograph on _The Grateful Dead_, published by the Folk-Lore Society in 1908. These stories usually represent the stranger as a dead man to whom the hero has rendered some service, such as that of burying his corpse. But perhaps the best known, and among the most ancient is that found in the book of Tobit, where the stranger is the angel Raphael. A tale even older and more widespread is preserved among the Hebrew traditions as that of Lot and the two angels who visited him in Sodom. Probably it was part of the common Semitic stock, and as such would have been known at Babylon. Substantially the same story is that of Baucis and Philemon reported by Ovid; and the tale of Demeter’s wanderings and many another in Greek legend rest on a common basis of belief. Continental folklore down to modern days {287} identifies the unknown beggar as Jesus Christ Himself or, if a woman, his Mother. The Bantu of South-West Africa tell of the great goddess Nzambi who begs in disguise for a little palm-wine to slake the thirst of her child. Refusal is followed in the night by punishment; the smiling valley, like that of Sodom, is covered by the waters of a lake; and the only person saved is he who had taken compassion and granted the poor old mendicant’s request.[287.1] Lest this be thought a tale imported from Europe, let me add that in Annam a similar tale is told to account for three lakes in the province of Thay Nguyen. There a beggar-woman is repulsed by all save an old widow and her son, who give of their poverty food and a night’s lodging to the miserable and unattractive creature. She turns out to be a supernatural personage. She has come down to test the hearts of the devotees who have flocked to a great religious festival periodically held in the place. The hypocrites who repulsed her are all overwhelmed in a deluge of waters; only the widow and her son are saved.[287.2]
