Aelian in his Varia Historia (lib. iii. ch. xviii.), states that Theopompus (400 b.c.) recorded an interview between the King of Phrygia and Silenus, in which the latter referred to the existence of a great continent beyond the Atlantic, larger than Asia, Europe and Libya together.
Proclus quotes an extract from an ancient writer who refers to the islands in the sea beyond the Pillars of Hercules (Straits of Gibraltar), and says that the inhabitants of one of these islands had a tradition from their ancestors of an extremely large island called Atlantis, which for a long time ruled over all the islands of the Atlantic Ocean.
Marcellus speaks of seven islands in the Atlantic, and states that their inhabitants preserve the memory of a much greater island, Atlantis, "which had for a long time exercised dominion over the smaller ones."
Diodorus Siculus relates that the Phœnicians discovered "a large island in the Atlantic Ocean beyond the Pillars of Hercules several days' sail from the coast of Africa."
But the greatest authority on this subject is Plato. In the Timæus he refers to the island continent, while the Critias or Atlanticus is nothing less than a detailed account of the history, arts, manners and customs of the people. In the Timæus he refers to "a mighty warlike power, rushing from the Atlantic sea and spreading itself with hostile fury over all Europe and Asia. For at that time the Atlantic sea was navigable and had an island before that mouth which is called by you the Pillars of Hercules. But this island was greater than both Libya and all Asia together, and afforded an easy passage to other neighbouring islands, as it was likewise easy to pass from those islands to all the continents which border on this Atlantic sea."
There is so much of value in the Critias that it is not easy to choose, but the following extract is given, as it bears on the material resources of the country: "They had likewise everything provided for them which both in a city and every other place is sought after as useful for the purposes of life. And they were supplied indeed with many things from foreign countries, on account of their extensive empire; but the island afforded them the greater part of everything of which they stood in need. In the first place the island supplied them with such things as are dug out of mines in a solid state, and with such as are melted: and orichalcum, which is now but seldom mentioned, but then was much celebrated, was dug out of the earth in many parts of the island, and was considered as the most honourable of all metals except gold. Whatever, too, the woods afforded for builders the island produced in abundance. There were likewise sufficient pastures there for tame and savage animals; together with a prodigious number of elephants. For there were pastures for all such animals as are fed in lakes and rivers, on mountains and in plains. And in like manner there was sufficient aliment for the largest and most voracious kind of animals. Besides this, whatever of odoriferous the earth nourishes at present, whether roots, or grass, or wood, or juices, or gums, flowers or fruits—these the island produced and produced them well."
The Gauls possessed traditions of Atlantis which were collected by the Roman historian, Timagenes, who lived in the first century, b.c. Three distinct peoples apparently dwelt in Gaul. First, the indigenous population (probably the remains of a Lemurian race), second, the invaders from the distant island of Atlantis, and third, the Aryan Gauls (see Pre-Adamites, p. 380).
The Toltecs of Mexico traced themselves back to a starting-point called Atlan or Aztlan; the Aztecs also claimed to come from Aztlan (see Bancroft's Native Races, vol. v. pp. 221 and 321).
The Popul Vuh (p. 294) speaks of a visit paid by three sons of the King of the Quiches to a land "in the east on the shores of the sea whence their fathers had come," from which they brought back amongst other things "a system of writing" (see also Bancroft, vol. v. p. 553).
Amongst the Indians of North America there is a very general legend that their forefathers came from a land "toward the sun-rising." The Iowa and Dakota Indians, according to Major J. Lind, believed that "all the tribes of Indians were formerly one and dwelt together on an island ... towards the sunrise." They crossed the sea from thence "in huge skiffs in which the Dakotas of old floated for weeks, finally gaining dry land."
