The great migration of the “heliolithic” culture-complex probably began shortly before 800 B.C. [Its influence in the Mediterranean and in Europe, as also in China and Japan, is merely mentioned incidentally in this communication.] Passing to the east the culture-complex reached the Persian Gulf strongly tainted with the influence of North Syria and Asia Minor, and when it reached the west coast of India and Ceylon, possibly as early as the end of the eighth century B.C., it had been profoundly influenced not only by these Mediterranean, Anatolian and especially Babylonian accretions, but even more profoundly with Eastern African modifications. These Ethiopian influences become more pronounced in Indonesia (no doubt because in India and the west the disturbances created by other cults have destroyed most of the evidence). From Indonesia the “heliolithic” culture-complex was carried far out into the Pacific and eventually reached the American coast, where it bore fruit in the development of the great civilizations on the Pacific littoral and isthmus, whence it gradually leavened the bulk of the vast aboriginal population of the Americas. [When this communication was made to the Society my sole object was to put together the scattered evidence supplied by the practice of mummification, and other customs associated with it, in substantiation of the fact that the influence of ancient Egyptian civilization, or a particular phase of it, had spread to the Far East and America. Since then so much new information has come to light, not only in confirmation of the main thesis, but also defining the dates of a series of cultural waves, that it will soon be possible, not only to sketch out in some detail the routes taken by the series of ancient mariners who spread abroad this peculiarly distinctive civilization, but also to identify the adventurers and determine the dates of their greatest exploits and the motives for most of their enterprises. In collaboration with Mr. J. W. Perry I hope soon to be ready to attempt that task. I have deliberately refrained from referring to the vexed question of totemism in this communication, although it is obvious that it is closely connected with the “heliolithic” culture. I have used the expression “serpent worship” in several places where perhaps it would have been more correct to refer to the serpent-totem; but so far from weakening, the consideration of totemism will add to the strength and cogency of my argument. When I assigned (p. 65) a comparatively late date for the extension of the “heliolithic” culture to the western Mediterranean and beyond I was not aware that Siret (_L’Anthropologie_, T. 20 and 21, 1909-10) had arrived at the same conclusion.] FOOTNOTES [1] These figures refer to the bibliography at the end.
