When a Brandenburg rustic has bought a horse in a neighboring town and rides him homeward, he dismounts at the boundary line of his own village, and, gathering a handful of his native soil, he throws it backward over the line to prevent the animal’s being bewitched. In Bohemia the chief signs of bewitchment in a horse are thought to be shivering, profuse sweating, and emaciation. A charm against this consists in drawing one’s shirt inside out over one’s head, and using it as a wherewithal to groom the animal,—a method which may be acceptable to superstitious jockeys and hostlers, but which will hardly commend itself to a fastidious horse-owner.[159] XII. HORSES’ HEADS AS TALISMANS In early times it was customary to use horses’ heads as talismans, by means of which also the ancient heathen nations practiced various magical arts. Grimm says in his “Teutonic Mythology” that the Scandinavians had a custom of fastening a horse’s head to a pole, with the mouth propped open with a stick. The gaping jaws were then turned in the direction whence an enemy was likely to come, in order to cast over him an evil spell. This contrivance was known as a spite-stake, or nithing-post. In Mallet’s “Northern Antiquities” (p. 156, 1890), it is related that Eigil, a famous Icelandic bard, on being banished from Norway in the ninth century, fixed a stake in the ground and fastened thereon a horse’s head, saying meanwhile: “I here set up a nithing-stake, and turn this my banishment against King Eirek and Queen Gunhilda.” Then, pointing the horse’s head toward the interior of Norway, he uttered a solemn imprecation against the protecting deities of the land, invoking evil upon them, and expressing a wish that they might be compelled to wander about and never find rest until they had driven forth the hated king and queen. In these cases the horse’s head was magically employed as an instrument for working evil upon an enemy, but later the same symbol was widely used among northern peoples as a talisman _against_ evil. Not alone in remote antiquity, but throughout the Middle Ages, the old pagan device of the spite-stake continued to be employed by the Teutonic peoples; and even after the Reformation, as late as the year 1584, a mare’s skull placed upon a pole was a favorite means for driving away rats and other vermin in Germany. The principle involved appears to have been always the same, namely, the power of averting evil supposed to be a magical attribute of horses’ heads; and this power was not only effective against human enemies, but likewise against the spirits of evil.[160] When the Roman general Cæcina Severus reached the scene of Varus’s defeat by the German tribes under their chieftain Arminius, in the year 9 A. D., near the river Weser, he saw numbers of horses’ heads fastened to the trunks of trees. These were the heads of Roman horses which the Germans had sacrificed to their gods.[161]
