So, at least, one explanation of orientation is found by such students of orientation as Sir Norman Lockyer.[138] Not only is orientation apparent in most of the temples of Egypt, Assyria, Babylonia, and the east, it is found in the Greek temples; Stonehenge is oriented to the midsummer sunrise, and so are most of the megalithic circles of Europe; the Temple of Heaven in Peking is oriented to midwinter. In the days of the Chinese Empire, up to a few years ago, one of the most important of all the duties of the Emperor of China was to sacrifice and pray in this temple upon midwinter’s day for a propitious year. The Egyptian priests had mapped out the stars into the constellations, and divided up the zodiac into twelve signs, by 3000 B.C. ... § 4 This clear evidence of astronomical inquiry and of a development of astronomical ideas is the most obvious, but only the most obvious, evidence of the very considerable intellectual activities that went on within the temple precincts in ancient times. There is a curious disposition among many modern writers to deprecate priesthoods and to speak of priests as though they had always been impostors and tricksters, preying upon the simplicity of mankind. But, indeed, they were for long the only writing class, the only reading public, the only learned and the only thinkers; they were all the professional classes of the time. You could have no intellectual life at all, you could not get access to literature or any knowledge except through the priesthood. The temples were not only observatories and libraries and clinics, they were museums and treasure-houses. The original _Periplus_ of Hanno hung in one temple in Carthage, skins of his “gorillas” were hung and treasured in another. Whatever there was of abiding worth in the life of the community sheltered there. Herodotus, the early Greek historian (485-425 B.C.), collected most of his material from the priests of the countries in which he travelled, and it is evident they met him generously and put their very considerable resources completely at his disposal. Outside the temples the world was still a world of blankly illiterate and unspeculative human beings, living from day to day entirely for themselves. Moreover, there is little evidence that the commonalty felt cheated by the priests, or had anything but trust and affection for the early priesthoods. Even the great conquerors of later times were anxious to keep themselves upon the right side of the priests of the nations and cities whose obedience they desired, because of the immense popular influence of these priests.
