Sec. 47. The greatest of these creations hare not been the work of any one man. They have been the slow product of the pious and poetic imagination. Starting from some personification of nature or some memory of a great man, the popular and priestly tradition has refined and developed the ideal; it has made it an expression of men's aspiration and a counterpart of their need. The devotion of each tribe, shrine, and psalmist has added some attribute to the god or some parable to his legend; and thus, around the kernel of some original divine function, the imagination of a people has gathered every possible expression of it, creating a complete and beautiful personality, with its history, its character, and its gifts. No poet has ever equalled the perfection or significance of these religious creations. The greatest characters of fiction are uninteresting and unreal compared with the conceptions of the gods; so much so that men have believed that their gods have objective reality. The forms men see in dreams might have been a reason for believing in vague and disquieting ghosts; but the belief in individual and well-defined divinities, with which the visions of the dreams might be identified, is obviously due to the intrinsic coherence and impressiveness of the conception of those deities. The visions would never have suggested the legend and attributes of the god; but when the figure of the god was once imaginatively conceived, and his name and aspect fixed in the imagination, it would be easy to recognize him in any hallucination, or to interpret any event as due to his power. These manifestations, which constitute the evidence of his actual existence, can be regarded as manifestations of him, rather than of a vague, unknown power, only when the imagination already possesses a vivid picture of him, and of his appropriate functions. This picture is the work of a spontaneous fancy. No doubt, when the belief is once specified, and the special and intelligible god is distinguished in the night and horror of the all-pervading natural power, the belief in his reality helps to concentrate our attention on his nature, and thus to develope and enrich our idea. The belief in the reality of an ideal personality brings about its further idealization. Had it ever occurred to any Greek seer to attribute events to the influence of Achilles, or to offer sacrifices to him in the heat of the enthusiasm kindled by the thought of his beauty and virtue, the legend of Achilles, now become a god, would have grown and deepened; it would have been moralized like the legend of Hercules, or naturalized like that of Persephone, and what is now but a poetic character of extraordinary force and sublimity would have become the adored patron of generation after generation, and a manifestation of the divine man.
