The ultimate, and what we may in a general sense term the classical, form in which this sense of the community of the Life principle found expression was that which endowed the vivifying force of Nature with a distinct personality, divine, or semi-divine, whose experiences, in virtue of his close kinship with humanity, might be expressed in terms of ordinary life. At this stage the progress of the seasons, the birth of vegetation in spring, or its revival after the autumn rains, its glorious fruition in early summer, its decline and death under the maleficent influence either of the scorching sun, or the bitter winter cold, symbolically represented the corresponding stages in the life of this anthropomorphically conceived Being, whose annual progress from birth to death, from death to a renewed life, was celebrated with a solemn ritual of corresponding alternations of rejoicing and lamentation. Recent research has provided us with abundant material for the study of the varying forms of this Nature Cult, the extraordinary importance of which as an evolutionary factor in what we may term the concrete expression of human thought and feeling is only gradually becoming realized.[2] Before turning our attention to this, the most important, section of our investigation, it may be well to consider one characteristic difference between the Nature ritual of the _Rig-Veda_, and that preserved to us in the later monuments of Greek antiquity. In the _Rig-Veda_, early as it is, we find the process of religious evolution already far advanced; the god has separated himself from his worshippers, and assumed an anthropomorphic form. Indra, while still retaining traces of his ‘weather’ origin, is no longer, to borrow Miss Harrison’s descriptive phrase, ‘an automatic explosive thunder-storm,’ he wields the thunderbolt certainly, but he appears in heroic form to receive the offerings made to him, and to celebrate his victory in a solemn ritual dance. In Greek art and literature, on the other hand, where we might expect to find an even more advanced conception, we are faced with one seemingly more primitive and inchoate, _i.e._, the idea of a constantly recurring cycle of Birth, Death, and Resurrection, or Re-Birth, of all things in Nature, this cycle depending upon the activities of an entity at first vaguely conceived of as the ‘Luck of the Year,’ the _Eniautos Daimon_. This Being, at one stage of evolution theriomorphic—he might assume the form of a bull, a goat, or a snake (the latter, probably from the close connection of the reptile with the earth, being the more general form)—only gradually, and by distinctly traceable stages, assumed an anthropomorphic shape.[3] This gives to the study of Greek antiquity a special and peculiar value, since in regard to the body of religious belief and observance with which we are here immediately concerned, neither in what we may not improperly term its ultimate (early Aryan), nor in what has been generally considered
