[267]. The progress of society brought men into association with useful plants, such as medicinal and edible herbs, and fruit-bearing and shade-giving trees; these, conceived of as inhabited by anthropomorphic spirits, fulfilled all the functions that attach to friendly animals. They became guardians and allies, totems and ancestors.[474] Several of the Central Australian totems are plants, and form part of the mythical ancestral population constructed by the imagination or ethnographic science of the people.[475] In Samoa a plant is often the incarnation of a spirit friendly to a particular family[476]—a conception that is not improbably a development from an earlier view that a certain plant had a special relation to a certain clan.[477] In general, a plant important in a given region (as, for example, the tobacco plant in North America) is likely to be invested with a sacred character.
[268]. Trees, by reason of their greater dignity (size, beauty, protective character), have generally been singled out as special cultic centers.[478] A great tree sometimes served as a boundary mark or signpost; under trees chiefs of clans sat to decide disputes. Thus invested with importance as a sort of political center as well as the abode of a spirit, a tree naturally became a shrine and an asylum.[479] In India and Greece, and among the ancient Celts and Germans, the gods were worshiped in groves, by the Canaanites and Hebrews "under every green tree." To cut down a sacred tree was a sacrilege, and the spirit of the tree was believed to avenge the crime.[480]
[269]. As might be expected, there is hardly a species of tree that has not been held sacred by some group of men. The Nagas and other tribes of Northeast India regard all plants as sacred,[481] and every village has its sacred tree. In Babylonia and Assyria, it is said, there were hundreds of trees looked on as invested with more or less sanctity. The oak was revered in some parts of Greece, and among the Romans and the Celts. The cult of particular species, as the pipal (Ficus religiosa), the vata or banyan (Ficus Indica), the karam and others, has been greatly systematized in India.[482]
[270]. Vegetable spirits in some cases have developed into real gods. A notable example of such growth is furnished by the history of the intoxicating soma plant, which in the Rig-Veda is represented not only as the inspiring drink of the gods but as itself a deity, doing things that are elsewhere ascribed to Indra, Pushan, and other well-established deities.[483] The spirit, coming to be regarded as an anthropomorphic person, under peculiar circumstances assumes the character of a god. A similar development appears in the Iranian haoma, and the cultic identity of soma and haoma shows that the deification of the plant took place in the early Aryan period.[484]
[271]. Another example has been supposed to be furnished by corn-spirits. The importance of cereal crops for human life gave them a prominent position in the cult of agricultural communities. The decay and revival of the corn was an event of prime significance, and appears to have been interpreted as the death and resurrection of the spirit that was the life of the crop. Such is the idea in the modern popular customs collected by Mannhardt and Frazer.[485] The similarity between these ceremonies and those connected with the Phœnician Tammuz (Adonis) and the Phrygian Attis makes it probable that the two are based on the same ideas; that is, that Adonis and Attis (and so also Osiris and Ishtar) were deities of vegetation. This, however, does not prove that they were developed out of spirits of vegetation; they may have been deities charged with the care of crops.[486] The Phœnician name Adon is merely a title ('lord') that might be given to any god; he whom the Greeks called Adonis was a Syrian local deity, identical in origin with the Babylonian Tammuz, and associated in worship with Astarte, whom the Greeks identified with their Aphrodite.
[272]. A sacred tree often stood by a shrine; that is, probably, the shrine was put in the spot made sacred by a tree, and a ritual connection between the two was thus established. Later, when a shrine for any reason (in consequence of a theophany, for example) was built where there was no tree, its place was supplied by a wooden post, which inherited the cultic value of a sacred tree. In the Canaanite cult, which was adopted by the Hebrews, the sacred post (called "ashera") stood by the side of every shrine, and was denounced by the prophets as an accompaniment of foreign (that is, non-Yahwistic) worship.[487] The transition from tree to post is illustrated, perhaps, by the conventionalized form of trees frequent on Babylonian seal cylinders.[488] How far the sacred post was an object of worship by the people we have no means of knowing; but by the more intelligent, doubtless, it came to be regarded simply as a symbol, a sign of the presence of a deity, and was, in so far, in the same category with images.[489]
[273]. It is not impossible that totem posts may be connected with original totem trees or other sacred trees. A tree as totem would naturally be the object of some sort of cult, and when it took the form of a post or pole, would have totemic symbols carved on it. Oftener, probably, it was the sacred pole of a village (itself descended from a sacred tree) that would be adorned with totemic figures, as among the Indians of Northwestern America.[490] In all such cases there is a coalescence of totemism and tree worship.
[274]. It was natural in early times, when most men lived in forests, which supplied all their needs, that trees should be looked on as intimately connected with human life. A tree might be regarded as in itself an independent personality, having, of course, a body and a soul, but not as dependent on an isolated spirit. A group of men might think itself descended from a tree—a conception that may have been widespread, though there is little direct evidence of its existence.[491] Indirect evidence of such a view is found in the custom of marrying girls to trees,[492] and in the belief in "trees of life," which are sometimes connected with individual men in such a way that when the tree or a part of it is destroyed the man dies, as in the case of Meleager whose life depended on the preservation of a piece of wood,[493] the representative, probably, of a tree, and the priest of Nemi whose life was bound up in the "golden bough"[494]; sometimes the tree has a magical power of conferring life on whoever eats of its fruit, as in the case of the tree of Eden.[495]
[275]. These stories involve the conception of blood-kinship between man and tree. Closely related to the "tree of life" is the "tree of knowledge"—life is knowledge and knowledge is life. In the original form of the story in Genesis there was only one tree—the tree of the knowledge of good and evil[496]—whose fruit, if eaten, made one the equal of the gods;[497] that is, the tree (in the original form of the conception, in remote times) was allied in nature (that is, in blood) to gods and to men, so that whoever partook of its substance shared its attribute of knowledge in sharing its life, and the command not to eat of it was due apparently to Yahweh's unwillingness that man should equal the gods in knowledge. The serpent-god, who belongs to the inner divine circle, but for some unexplained reason is hostile to the god of the garden,[498] reveals the secret.
[276]. Probably, also, it is from this general order of ideas that the conception of the cosmic tree has sprung. The Scandinavian Yggdrasil is the source of life to all things and represents also wisdom; though the details may contain Christian elements, the general conception of the world as a tree or as nourished by a tree is probably old.[499] The same conception appears in the cosmic tree of India.[500] Such quasi-philosophical ideas of the unity of the life of the world suppose, doubtless, a relatively advanced stage of culture, but they go back to the simple belief that the tree is endowed with life and is a source of life for men. The transition to the cosmic conception may be found in those quasi-divine trees that grant wishes and endow their friends with wisdom and life.
