In the chapter on "Conjurations and Exorcisms among the Hungarian Gypsies," I have mentioned the importance which they attach to the being born a seventh or twelfth child. This is the same throughout South Slavonia, where the belief that such persons in a series of births are exceptionally gifted is "shared by both gypsies, with whom it probably originated, and the peasants. What renders this almost certain is that Dr. Krauss mentions that the oldest information as to the subject among the Slavs dates only from 1854, while the faith is ancient among the gypsies. He refers here to the so-called Kerstniki, who on the eve of St. John do battle with the witches. Krstnik is a Greek word, meaning, literally, one who has been baptized. But the Krstnik proper is the youngest of twelve brothers, all sons of the same father. There appears to be some confusion and uncertainty among the Slavs as to whether all the twelve brothers or only the twelfth are "Krstnik"--according to the gypsy faith it would be the latter. These "twelvers" are the great protectors of the world from witchcraft. [17] But they are in great danger on Saint John's Eve, for then the witches, having most power, assail them with sticks and stakes, or stumps of saplings, for which reason it is usual in the autumn to carefully remove everything of the kind from the ground. A krstnik is described by Miklosic as "Clovek kterega vile obljubiju"--"A man who has won the love of a Vila." The Vila ladies, or a certain class of them, are extremely desirous of contracting the closest intimacy--in short, of becoming the mistresses, of superior men. The reader may find numerous anecdotes of such amours in the "Curiosa" of Heinrich Kornmann, 1666, and in my "Egyptian Sketch Book" (Trübner & Co., London, 1874). In the heathen days, as at present among all gypsies and Orientals, it was believed to be a wonderfully lucky thing for a man to get the love of one of these beautiful beings. What the difficulties were which kept them from finding lovers is not very clear, unless it were that the latter must be twelfth sons, or, what is far more difficult to find, young men who would not gossip about their supernatural sweethearts to other mortals, who would remain true to them, and who finally would implicitly obey all their commands and follow their advice. There is a vast array of tales--Gypsy, Arab, Provençal, Norman, German, and Scandinavian, which show that on these points the Vila, or forest-maiden, or spirit of earth or air, or fairy, was absolutely exacting and implacable, being herself probably allowed by occult laws to contract an intimacy only with men of a high order, or such as are-- "Few in a heap and very hard to find."
