The use of amulets has been attributed to religious sentimentality or religiosity. The latter word has been defined as "an excessive susceptibility to the religious sentiments, especially wonder, awe, and reverence, unaccompanied by any correspondent loyalty to divine law in daily life."[4:3] Any one desirous of moralizing on the subject may find a theme presenting aspects both sad and comical. When, however, one reflects that amulets, in some one of their protean forms, have been invested with supernatural preventive and healing powers by the people of all lands and epochs, and that they have been worn not only by kings and princes, but by philosophers, prelates, and physicians of eminence as well, it is evident that the subject deserves more than a passing consideration. It would be vain to seek the origin of their employment, which lies hidden behind the misty veil of remote antiquity. The eastern nations of old, as is well known, were much addicted to the use of amulets; and from Chaldea, Egypt, and Persia the practice was transmitted westward, and was thus extended throughout the civilized world. Among the great number of popular amulets in ancient times, many were fashioned out of metals, ivory, stone, and wood, to represent deities, animals, birds, and fishes; others were precious stones or cylinders inscribed with hieroglyphics; necklaces of shell or coral, crescent- or hand-shaped charms, and grotesque images. Their virtues were derived either from the material, from the shape, or from the magic rites performed at the time of their preparation. According to a popular belief, which prevailed throughout the East in the earlier centuries of the Christian era, all objects, whether inanimate stones and metals, or brutes and plants, possessed an indwelling spirit or soul, which was the cause of the efficiency of all amulets.[5:1] They were therefore akin to fetishes, in the present acceptation of the term; for a fetish, as defined in the classification of medicines and therapeutic agents in the collections of the National Museum at Washington, D. C., is a material object supposed to be the abode of a spirit, or representing a spirit, which may be induced or compelled to help the possessor. According to Juvenal ("Satires," Book III, v, 1), Grecian athletes wore protective charms in the arena, to counterbalance the magical devices of their opponents. It is probable that the ethics of modern athletic contests would not countenance such expedients. But so implicit was the confidence of the Roman citizen in his amulet, that a failure to avert sickness or evil of any sort was not attributed to inherent lack of power in the charm itself, but rather to some mistake in the method of its preparation.[6:1]
