The association of acts of worship with certain specially sacred objects or places lies at the basis of much religious art, though very often art has little or nothing to do with such objects in a primitive stage of religious development. Stocks and stones--the latter often reputed to have fallen from heaven, the former sometimes in the shape of a growing tree, sometimes of a mere unwrought log--were to be found as the centres of religious cult in many of the shrines of Greece. These sacred objects are sometimes called fetishes; and although it is perhaps wiser to avoid terms belonging properly to the religion of modern savages in speaking of ancient Greece, there seems to be an analogy between the beliefs and customs that are implied. Such sacred stocks or stones were not regarded merely as symbols of certain deities, but were looked upon as having certain occult or magic qualities inherent in them, and as being in themselves potent for good or evil. The ceremonies used in their cult partook of the nature of magic rather than religion, so far as these consisted of anointing them with oil or with drink offerings; such ceremonies might, indeed, be regarded as gratifying to the deity worshipped under their form, when they were definitely affiliated to the service of an anthropomorphic god; but in a more primitive stage of belief the indwelling power probably was not associated with any such generalisation as is implied in the change from "animism" or "polydaemonism" to polytheism. We are here concerned not with this growth of religious feeling, but rather with its influence upon the sacred things that were objects of worship and with the question how far their sanctity encouraged their artistic decoration.
