About five hundred and seventy years before the Christian era, Solon, the celebrated legislator of Greece, visited Egypt, and while there became acquainted with some of the erudite priests of the country.[2] When the latter communicated to him what they had learned from the records concerning the ancient peoples of the earth, the sage of Greece was so deeply impressed with the unquestionable value of this strange information that he committed it to writing, intending to use it in an historical poem which he had undertaken to compose.[3] On his return to Athens he was not permitted the leisure that was needed to complete his agreeable task.[4] After his death, the compilations he had made in Egypt were, for a long time, preserved by his descendants, and at last became the property of Plato, the Greek philosopher.[5] The latter, when a boy, had studiously perused his eminent ancestor’s manuscript, and when he had reached the last years of his scholarly life he could not disengage his thoughts from the conviction that it was his personal duty to publish its rare information.[6] In order, therefore, to give publicity to Solon’s valuable compilations, Plato, a short time before his own death, wrote that part of the unfinished dialogue entitled “Critias, or the Atlantic,” in which appears the earliest known account of the ancient people of the western hemisphere.[7] “When Solon interrogated the priests, who were the most distinguished for their antiquarian knowledge, he became aware that neither he nor any of the Greeks knew much concerning the history of the first ages of the world.

Thereupon one of the eldest priests exclaimed: ‘Solon, Solon, you Greeks are but children, and an aged Greek there is none!’ Solon, hearing this, asked, ‘What do you mean?’ The priest replied: ‘You are all youths in intelligence, for you have no old beliefs transmitted by tradition, nor any science hoary with age.... From the olden time we have chronicled whatever has happened in your country or in ours, or in any other region known to us,—any action, noble or great or in any other way remarkable,—and these records are preserved in our temples, whereas you and other nations have but lately been provided with letters and different things required by states....
