"Very fair and full of promise Lay the island of St. Thomas; Like a great green turtle slumbered On the sea which it encumbered." Here we have, too, the four quarters of Atlantis, divided by its four rivers, as we shall see a little farther on, represented in a dance, where the dancers arrange themselves according to the four cardinal points of the compass; the dancers are painted to represent the black and red races, while "the first and only man" represents the white race; and the name of the dance is a reminiscence of Baal, the ancient god of the races derived from Atlantis. But this is not all. The Mandans were evidently of the race of Atlantis. They have another singular legend, which we find in the account of Lewis and Clarke: "Their belief in a future state is connected with this theory of their origin: The whole nation resided in one large village, underground, near a subterranean lake. A grape-vine extended its roots down to their habitation, and gave them a view of the light. Some of the most adventurous climbed up the vine, and were delighted with the sight of the earth, which they found covered with buffalo, and rich with every kind of fruit. Returning with the grapes they had gathered, their countrymen were so pleased with the taste of them that the whole nation resolved to leave their dull residence for the charms of the upper region. Men, women, and children ascended by means of the vine, but, when about half the nation had reached the surface of the earth, a corpulent woman, who was clambering up the vine, broke it with her weight, and closed upon herself and the rest of the nation the light of the sun." This curious tradition means that the present nation dwelt in a large settlement underground, that is, beyond the land, in the sea; the sea being represented by "the subterranean lake." At one time the people had free intercourse between this "large village" and the American continent, and they founded extensive colonies on this continent; whereupon some mishap cut them off from the mother country. This explanation is confirmed by the fact that in the legends of the Iowa Indians, who were a branch of the Dakotas, or Sioux Indians, and relatives of the Mandans (according to Major James W. Lynd), "all the tribes of Indians were formerly one, and all dwelt together on an island, or at least across a large water toward the east or sunrise. They crossed this water in skin canoes, or by swimming; but they know not how long they were in crossing, or whether the water was salt or fresh." While the Dakotas, according to Major Lynd, who lived among them for nine years, possessed legends of "huge skiffs, in which the Dakotas of old floated for weeks, finally gaining dry land"--a reminiscence of ships and long sea-voyages.
