1. The early traditions of every nation that has undertaken to relate the story of its origin, have given us a confused account of supernatural persons and events which the judgment of more enlightened times has almost uniformly considered fabulous and impossible. It has always been an interesting inquiry how much of fact was veiled under this mythical dress, and a great variety of ingenious and contradictory explanations have been produced by the learned in all ages. In most cases, as in Greece, the national religion has been based on these legends which form its authority and explanation, and they passed with the people of all early times as facts which it was impious to question. So the wise and good Socrates was supposed to have denied the existence of the national gods, and was condemned to death. This sacred guard placed over early traditions, increased at once the interest and the difficulty involved in their examination. 2. During the present century the improved methods, larger range and more exact style of inquiry, and the assistance and hints which one branch of study has given to others, have produced the most surprising and satisfactory results. These inquiries are not yet complete; they seem, on the contrary, to have only commenced, and promise, ultimately, to satisfy all the useful purposes and legitimate curiosity of mankind; still, their conclusions, so far as they go, are unimpeachable. They prove themselves. The study of Ethnology, which gives an account of the races of mankind; a critical comparison of all languages, ancient and modern; the patient study and ingenious deciphering of architecture and inscriptions found in ancient ruins, and various relics of human activity imbedded in the soil of different countries, have thrown down the barriers which the glowing imaginations of the poets and the want of authentic documents in early times had raised, and have given us a clue to many of the secrets of history, and a safe guide through some of the dark passages of man’s primitive life. To show how this is done would require a treatise on Ethnology, another on Comparative Philology, a third on Antiquarian Research, and a fourth on the Geological Antiquities of Man. Each of these brings a large and valuable contribution to early history. We give only a brief summary of their conclusions. 3. The human race appears to have had its birth on the high table lands of central Asia, south and east of the Caspian Sea. The structure and growth of language, and the remains of early art, indicate an extremely infantile mental condition and successive emigrations from the primitive home of the race. Families and tribes which had remained together long enough to build up a common language and strong general features of character and habit, at length separated and formed a number of families of allied races.
