10. All these suggestive and poetical fancies would in themselves suffice to make the tree-symbol a favorite one among so thoughtful and profound a people as the old Chaldeans. But there is something more. It is intimately connected with another tradition, common, in some form or other, to all nations who have attained a sufficiently high grade of culture to make their mark in the world--that of an original ancestral abode, beautiful, happy, and remote, a Paradise. It is usually imagined as a great mountain, watered by springs which become great rivers, bearing one or more trees of wonderful properties and sacred character, and is considered as the principal residence of the gods. Each nation locates it according to its own knowledge of geography and vague, half-obliterated memories. Many texts, both in the old Accadian and the Assyrian languages, abundantly prove that the Chaldean religion preserved a distinct and reverent conception of such a mountain, and placed it in the far north or north-east, calling it the "Father of Countries," plainly an allusion to the original abode of man--the "Mountain of Countries," (i.e., "Chief Mountain of the World") and also ARALLU, because there, where the gods dwelt, they also imagined the entrance to the Arali to be the Land of the Dead. There, too, the heroes and great men were to dwell forever after their death. There is the land with a sky of silver, a soil which produces crops without being cultivated, where blessings are for food and rejoicing, which it is hoped the king will obtain as a reward for his piety after having enjoyed all earthly goods during his life.[AX] In an old Accadian hymn, the sacred mount, which is identical with that imagined as the pillar joining heaven and earth, the pillar around which the heavenly spheres revolve, (see page 153)--is called "the mountain of Bel, in the east, whose double head reaches unto the skies; which is like to a mighty buffalo at rest, whose double horn sparkles as a sunbeam, as a star." So vivid was the conception in the popular mind, and so great the reverence entertained for it, that it was attempted to reproduce the type of the holy mountain in the palaces of their kings and the temples of their gods. That is one of the reasons why they built both on artificial hills. There is in the British Museum a sculpture from Koyunjik, representing such a temple, or perhaps palace, on the summit of a mound, converted into a garden and watered by a stream which issues from the "hanging garden" on the right, the latter being laid out on a platform of masonry raised on arches; the water was brought up by machinery. It is a perfect specimen of a "Paradise," as these artificial parks were called by the Greeks, who took the word (meaning "park" or "garden") from the Persians, who, in their turn, had borrowed the thing from the Assyrians and Babylonians, when they conquered the latter's empire.
