The Tree of Life = The Tree of Knowledge
“But the cedar was something more than a world-tree. It was employed, as we have seen, in incantations and magic rites which were intended to restore strength and life to the human frame. It was thus essentially “a tree of life,” and the prototype and original of those conventional trees of Iife with which the walls of the Assyrian paiaces were adorned.
Those who have visited the Assyrian collection of the British Museum will remember the curious form which it generally assumes, as well as the figures of the two cherubs which kneel or stand before it on either side. At times they are purely human; at other times they have the head of a hawk and hold a cone–the fruit of the cedar–over the tree by whose side they stand.
It is possible that, as time went on, another tree became confounded with the original tree of life. The palm was from the earliest period characteristic of Babylonia; and while its fruit seemed to be the stay and support of life, the wine made from it made “glad the heart of man.”
Date-wine was largely used, not only in Babylonian medicine, but in the religious and magical ceremonies of Babylonia as well. It is not at all improbable, therefore, that the later Babylonian tree of life, with its strange conventional form, was an amalgamation of two actual trees, the cedar and the palm.
It is even possible that while one of them, the cedar, was primarily the sacred tree of Eridu, the other was originally the sacred tree of some other locality of Chaldea.
What gives some colour to this last suggestion is, that in later Babylonian belief the tree of life and the tree of knowledge were one and the same.
The text which describes the initiation of a soothsayer associates the cedar with “the treasures of Anu, Bel and Ea, the tablets of the gods, the delivering of the oracle of heaven and earth.” It was upon the heart or core of the cedar, too, that the name of Ea, the god of wisdom, was inscribed.
And it was wisdom rather than life, the knowledge of the secrets of heaven and the magical arts that benefit or injure, which the priesthood of Babylonia and the gods they worshipped kept jealously guarded.
Only the initiated were allowed to taste of its fruit. In this respect, consequently, there was a marked difference between the belief of the Babylonians and the account which we find in the earlier chapters of Genesis.”
