There is also the famous so-called zodiac of Denderah, brought from Egypt to Paris. This in reality contains more constellations than those of the zodiac. Most of the northern ones can be traced, with certain modifications. Its construction is supposed to belong to the eighth century B.C. Most conspicuous on it is the Lion, in a kind of barque, recalling the shape of the Hydra. Below it is the calf Isis, with Sirius, or the Dog-Star, on the forehead; above it is the Crab, to the right the Twins, over these along instrument, the Plough, and above that a small animal, the Little Bear, and so we may go on:--all the zodiacal constellations, especially the Balance, the Scorpion, and the Fishes being very clear. This sphere is indeed of later date than that supposed for the Grecian, but it certainly appears to be independent. The remains we possess of older spheres are more particularly connected with the zodiac, and will be discussed hereafter. From what people the Greeks received the celestial sphere, is a question on which more than one opinion has been formed. One is that it was originated in the tropical latitudes of Egypt. The other, that it came from the Chaldeans, and a third that it came from more temperate latitudes further to the east. The arguments for the last of these are as follow: There is an empty space of about 90 deg., formed by the last constellations of the sphere, towards the south pole, that is by the Centaur, the Altar, the Archer, the Southern Fish, the Whale, and the Ship. Now in a systematic plan, if the author were situated near the equator there would be no vacant space left in this way, for in this case the southern stars, attracting as much attention as the northern, would be inevitably inserted in the system of constellations which would be extended to the horizon on all sides. But a country of sufficiently high latitude to be unable to see at any time the stars about the southern pole must be north both of Egypt and Chaldea. This empty space remained unfilled until the discovery of the Cape of Good Hope, except that the star Canopus was included in the constellation Argo, and the river Eridan had an arbitrary extension given to it, instead of terminating in latitude 40 deg.. Another less cogent argument is derived from the interpretation of the fable of the Phoenix. This is supposed to represent the course of the sun, which commences its growth at the time of its death. A similar fable is found among the Swedes. Now a tropical nation would find the difference of days too little to lead it to invent such a fable to represent it. It must needs have arisen where the days of winter were very much shorter than those of summer.
