The symbolic mountain Meru was ascended by Seven steps or stages; and all the pyramids and artificial tumuli and hillocks thrown up in flat countries were imitations of this fabulous and mystic mountain, for purposes of worship. These were the "High Places" so often mentioned in the Hebrew books, on which the idolaters sacrificed to foreign gods. The pyramids were sometimes square, and sometimes round. The sacred Babylonian tower [[Hebrew: מגדל], Magdol], dedicated to the great Father Bal, was an artificial hill, of pyramidal shape, and Seven stages, built of brick, and each stage of a different color, representing the Seven planetary spheres by the appropriate color of each planet. Meru itself was said to be a single mountain, terminating in three peaks, and thus a symbol of the Trimurti. The great Pagoda at Tanjore was of six stories, surmounted by a temple as the seventh, and on this three spires or towers. An ancient pagoda at Deogur was surmounted by a tower, sustaining the mystic egg and a trident. Herodotus tells us that the Temple of Bal at Babylon was a tower composed of Seven towers, resting on an eighth that served as basis, and successively diminishing in size from the bottom to the top; and Strabo tells us it was a pyramid. Faber thinks that the Mithriac _ladder_ was really a pyramid with Seven stages, each provided with a narrow door or aperture, through each of which doors the aspirant passed, to reach the summit, and then descended through similar doors on the opposite side of the pyramid; the ascent and descent of the Soul being thus represented. Each Mithriac cave and all the most ancient temples were intended to symbolize the Universe, which itself was habitually called the Temple and habitation of Deity. Every temple was the world in miniature; and so the whole world was one grand temple. The most ancient temples were roofless; and therefore the Persians, Celts, and Scythians strongly disliked artificial covered edifices. Cicero says that Xerxes burned the Grecian temples, on the express ground that the whole world was the Magnificent Temple and Habitation of the Supreme Deity. Macrobius says that the entire Universe was judiciously deemed by many the Temple of God. Plato pronounced the real Temple of the Deity to be the world; and Heraclitus declared that the Universe, variegated with animals and plants and stars was the only genuine Temple of the Divinity.
