Again, effigies are often employed as a means of preventing or curing sickness; the demons of disease either mistake the effigies for living people or are persuaded or compelled to enter them, leaving the real men and women well and whole. Thus the Alfoors of Minahassa, in Celebes, will sometimes transport a sick man to another house, while they leave on his bed a dummy made up of a pillow and clothes. This dummy the demon is supposed to mistake for the sick man, who consequently recovers. Cure or prevention of this sort seems to find especial favour with the natives of Borneo. Thus, when an epidemic is raging among them, the Dyaks of the Katoengouw River set up wooden images at their doors in the hope that the demons of the plague may be deluded into carrying off the effigies instead of the people. Among the Oloh Ngadju of Borneo, when a sick man is supposed to be suffering from the assaults of a ghost, puppets of dough or rice-meal are made and thrown under the house as substitutes for the patient, who thus rids himself of the ghost. In certain of the western districts of Borneo if a man is taken suddenly and violently sick, the physician, who in this part of the world is generally an old woman, fashions a wooden image and brings it seven times into contact with the sufferer's head, while she says: This image serves to take the place of the sick man; sickness, pass over into the image. Then, with some rice, salt, and tobacco in a little basket, the substitute is carried to the spot where the evil spirit is supposed to have entered into the man. There it is set upright on the ground, after the physician has invoked the spirit as follows: O devil, here is an image which stands instead of the sick man. Release the soul of the sick man and plague the image, for it is indeed prettier and better than he. Batak magicians can conjure the demon of disease out of the patient's body into an image made out of a banana-tree with a human face and wrapt up in magic herbs; the image is then hurriedly removed and thrown away or buried beyond the boundaries of the village. Sometimes the image, dressed as a man or a woman according to the sex of the patient, is deposited at a cross-road or other thoroughfare, in the hope that some passer-by, seeing it, may start and cry out, Ah! So-and-So is dead; for such an exclamation is supposed to delude the demon of disease into a belief that he has accomplished his fell purpose, so he takes himself off and leaves the sufferer to get well.
The Mai Darat, a Sakai tribe of the Malay Peninsula, attribute all kinds of diseases to the agency of spirits which they call nyani; fortunately, however, the magician can induce these maleficent beings to come out of the sick person and take up their abode in rude figures of grass, which are hung up outside the houses in little bell-shaped shrines decorated with peeled sticks. During an epidemic of small-pox the Ewe negroes will sometimes clear a space outside of the town, where they erect a number of low mounds and cover them with as many little clay figures as there are people in the place. Pots of food and water are also set out for the refreshment of the spirit of small-pox who, it is hoped, will take the clay figures and spare the living folk; and to make assurance doubly sure the road into the town is barricaded against him.
With these examples before us we may surmise that the woollen effigies, which at the festival of the Compitalia might be seen hanging at the doors of all the houses in ancient Rome, were not substitutes for human victims who had formerly been sacrificed at this season, but rather vicarious offerings presented to the Mother or Grandmother of Ghosts, in the hope that on her rounds through the city she would accept or mistake the effigies for the inmates of the house and so spare the living for another year. It is possible that the puppets made of rushes, which in the month of May the pontiffs and Vestal Virgins annually threw into the Tiber from the old Sublician bridge at Rome, had originally the same significance; that is, they may have been designed to purge the city from demoniac influence by diverting the attention of the demons from human beings to the puppets and then toppling the whole uncanny crew, neck and crop, into the river, which would soon sweep them far out to sea. In precisely the same way the natives of Old Calabar used periodically to rid their town of the devils which infested it by luring the unwary demons into a number of lamentable scarecrows, which they afterwards flung into the river. This interpretation of the Roman custom is supported to some extent by the evidence of Plutarch, who speaks of the ceremony as the greatest of purifications.
