(M112) Thus misled by a double fallacy primitive philosophy comes to view the moon as the great cause of vegetable growth, first, because the planet seems itself to grow, and second, because it is supposed to be the source of dew and moisture. It is no wonder, therefore, that agricultural peoples should adore the planet which they believe to influence so profoundly the crops on which they depend for subsistence. Accordingly we find that in the hotter regions of America, where maize is cultivated and manioc is the staple food, the moon was recognized as the principal object of worship, and plantations of manioc were assigned to it as a return for the service it rendered in the production of the crops. The worship of the moon in preference to the sun was general among the Caribs, and, perhaps, also among most of the other Indian tribes who cultivated maize in the tropical forests to the east of the Andes; and the same thing has been observed, under the same physical conditions, among the aborigines of the hottest region of Peru, the northern valleys of Yuncapata. Here the Indians of Pacasmayu and the neighbouring valleys revered the moon as their principal divinity. The “house of the moon” at Pacasmayu was the chief temple of the district; and the same sacrifices of maize-flour, of wine, and of children which were offered by the mountaineers of the Andes to the Sun-god, were offered by the lowlanders to the Moon-god in order that he might cause their crops to thrive.(369) In ancient Babylonia, where the population was essentially agricultural, the moon-god took precedence of the sun-god and was indeed reckoned his father.(370) (M113) Hence it would be no matter for surprise if, after worshipping the crops which furnished them with the means of subsistence, the ancient Egyptians should in later times have identified the spirit of the corn with the moon, which a false philosophy had taught them to regard as the ultimate cause of the growth of vegetation. In this way we can understand why in their most recent forms the myth and ritual of Osiris, the old god of trees and corn, should bear many traces of efforts made to bring them into a superficial conformity with the new doctrine of his lunar affinity. CHAPTER IX. THE DOCTRINE OF LUNAR SYMPATHY. (M114) In the preceding chapter some evidence was adduced of the sympathetic influence which the waxing or waning moon is popularly supposed to exert on growth, especially on the growth of vegetation. But the doctrine of lunar sympathy does not stop there; it is applied also to the affairs of man, and various customs and rules have been deduced from it which aim at the amelioration and even the indefinite extension of human life. To illustrate this application of the popular theory at length would be out of place here, but a few cases may be mentioned by way of specimen.
