and that to eliminate them from the national consciousness would have been impossible. A nucleus of fact may, therefore, have formed the basis of certain myths, just as a wire immersed in a solution of salts will cause the fluid to condense in crystals round it. But, as in the case just used by way of illustration, we do not see the wire, but the crystals, after the process has been finished, so in mythology it is not the fact but the fancy which attracts our attention and calls for our consideration. This illustration might be extended so as to apply to any substratum, linguistic, solar, symbolical, or other, that may be supposed to underlie the fancy-fabric of mythology. The truth to be looked for in myths is psychological, not historical, æsthetic rather than positive. In order to make the relation of actuality to imagination in the mythopoeic process still more intelligible, another illustration can be drawn from nature. Pearls are said to be the result of a secretion effused from the pearl-oyster round a piece of grit or thorn inserted between its flesh and the shell in which it lives. To the production of the pearl this extraneous object and the irritation which it causes are both necessary; yet the pearl is something in itself quite independent of the stimulating substance. Just so the myth, which corresponds to the pearl, is a secretion of the national imagination which has been roused into activity by something accidental and exterior. It is possible to take a fifth line and to refer mythology to fetichism. Strictly speaking, fetichism can never explain the problem of the mythopoeic faculty, except in so far as we may assume it to have formed a necessary stage of human development anterior to polytheism. Greek mythology, together with Greek nature-worship, would, according to this fifth method of interpretation, have to be regarded as a refinement on the savage dread of fetiches. Beginning with a servile prostration before the powers of nature, this attitude of simple awe would have been gradually elevated to the height which it attained in Homer and Hesiod. In the progressive amelioration of the race myths would thus have occupied a middle place between the fetich and the free divinities of art. Putting aside all the difficulties which involve the question whether fetichism is rightly regarded as the first attitude of man towards nature, it is clear that the fetichistic hypothesis cannot cover the whole field of our inquiry. What it does do is to offer an explanation of the origin of nature-worship, and to account for the fact that external objects are regarded as living, sentient beings in the myths. Long before the philosophers of Ionia conjectured that the stars are fiery vapors, people fancied they were gods. It has been well observed that the Greeks never speak of a god _of the_ sun, or a goddess _of the_ moon. They worshipped the sun as a god in Helios, the moon as a goddess in Selene. This direct reference of the
