This independence and originality of Greek literature is due in some measure to the freedom of their institutions from caste; but another and more powerful cause was that, unlike the Oriental nations, the Greeks for a long time kept no correct record of their transactions in war or peace. This absence of authentic history made their literature become what it is. By the purely imaginary character of its poetry, and the freedom it enjoyed from the trammels of particular truths, it acquired a quality which led Aristotle to consider poetry as more philosophical than history. The Homeric poems are in a great measure the fountainhead from which the refinement of the Ancients was derived. The history of the Iliad and the Odyssey represent a state of society warlike it is true, but governed by intellectual, literary and artistic power. Philosophy was early cultivated by the Greeks, who first among all nations distinguished it from religion and mythology. Socrates is the founder of the philosophy that is still recognized in the civilized world. He left no writings behind him; but by means of lectures, that included question and answer, his system, known as the dialectics, has come down to us. Aesop, who lived 572 B.C., was the author of some fables which have been translated into nearly every language in the world, and have served as a model for all subsequent writings of the same kind. In 322 B.C., the centre of learning owing to the conquests of Alexander the Great, was moved to Egypt in the city that bears his name. Here the first three Ptolemies founded a magnificent library where the literary men of the age were supported by endowments. The second Ptolemy had the native annals of Egypt and Judea translated into Greek, and he procured from the Sanhedrim of Jerusalem the first part of the Sacred Scriptures, which was later completed and published in Greek for the use of the Jews at Alexandria. This translation was known as the Septuagint, or version of the Seventy; and is said to have exercised a more lasting influence on the civilized world than any book that has ever appeared in a new language. We are indebted to the Ptolemies for preserving to our times all the best specimens of Greek literature that have come down to us. THE NEW TESTAMENT AND THE GREEK FATHERS. The interdependence of Greek literature includes some reference to the Greek fathers and their writings.
