If knots are supposed to kill, they are also supposed to cure. This follows from the belief that to undo the knots which are causing sickness will bring the sufferer relief. But apart from this negative virtue of maleficent knots, there are certain beneficent knots to which a positive power of healing is ascribed. Pliny tells us that some folk cured diseases of the groin by taking a thread from a web, tying seven or nine knots on it, and then fastening it to the patient's groin; but to make the cure effectual it was necessary to name some widow as each knot was tied. O'Donovan describes a remedy for fever employed among the Turcomans. The enchanter takes some camel hair and spins it into a stout thread, droning a spell the while. Next he ties seven knots on the thread, blowing on each knot before he pulls it tight. This knotted thread is then worn as a bracelet on his wrist by the patient. Every day one of the knots is untied and blown upon, and when the seventh knot is undone the whole thread is rolled up into a ball and thrown into a river, bearing away (as they imagine) the fever with it.
Again knots may be used by an enchantress to win a lover and attach him firmly to herself. Thus the love-sick maid in Virgil seeks to draw Daphnis to her from the city by spells and by tying three knots on each of three strings of different colours. So an Arab maiden, who had lost her heart to a certain man, tried to gain his love and bind him to herself by tying knots in his whip; but her jealous rival undid the knots. On the same principle magic knots may be employed to stop a runaway. In Swazieland you may often see grass tied in knots at the side of the footpaths. Every one of these knots tells of a domestic tragedy. A wife has run away from her husband, and he and his friends have gone in pursuit, binding up the paths, as they call it, in this fashion to prevent the fugitive from doubling back over them. A net, from its affluence of knots, has always been considered in Russia very efficacious against sorcerers; hence in some places, when a bride is being dressed in her wedding attire, a fishing-net is flung over her to keep her out of harm's way. For a similar purpose the bridegroom and his companions are often girt with pieces of net, or at least with tight-drawn girdles, for before a wizard can begin to injure them he must undo all the knots in the net, or take off the girdles. But often a Russian amulet is merely a knotted thread. A skein of red wool wound about the arms and legs is thought to ward off agues and fevers; and nine skeins, fastened round a child's neck, are deemed a preservative against scarlatina. In the Tver Government a bag of a special kind is tied to the neck of the cow which walks before the rest of a herd, in order to keep off wolves; its force binds the maw of the ravening beast. On the same principle, a padlock is carried thrice round a herd of horses before they go afield in the spring, and the bearer locks and unlocks it as he goes, saying, "I lock from my herd the mouths of the grey wolves with this steel lock."
Knots and locks may serve to avert not only wizards and
