Turning to the religions which have preserved their primitive forms to modern times, the first place should be conceded to those of America. Up to four hundred years ago, all of them, throughout the continent, had developed from an unknown antiquity untouched by the teachings of Asian or European instructors; for no really sane scholar nowadays believes either that St. Thomas preached Christianity in the New World in the first century, or that Buddhist monks in the seventh or any other century carried their tenets into Mexico and Guatemala.
Many of the American tribes, moreover, lived in the rudest stages of social life, ignorant of agriculture, without fixed abodes, naked or nearly so, in constant bloody strife, destitute even of tribal government. Here, if anywhere, we should find the religious sentiment, if it exists at all, in its simplest elements.
On the other hand, the first European explorers found in Peru, Yucatan, and Mexico numerous tribes in almost a civilised condition, builders of huge edifices of carved stones, cultivating the soil, and acquainted with a partly phonetic system of writing. Their mythology was ample and their ritual elaborate, so that it could scarcely be called primitive in appearance; but in all these instances, myth and ritual were so obviously identical in character with those of the vagrant tribes elsewhere, that we shall make no mistake in classifying them together.
Equally isolated and surely as rude as the rudest were the native Australians, the wavy-haired, bearded, black people who sparsely inhabited that huge island, two thousand miles wide by two thousand five hundred miles long. Isolated by arid stretches of desert, the struggle for life was incessant, and there is little wonder that we find them in an incredibly debased condition associated with unending war and cannibalism. For these very reasons, their religious notions deserve our closest scrutiny.
The vast island-world of Polynesia was peopled by related tribes, usually of limited cultivation, but with a rich mythology, of which we have many strange and beautiful fragments. They are primitive in form and expression, with singular differences as well as analogies to the beliefs of continental tribes.
