The school of Alexandria, founded by one named Mark, to whom succeeded Athenagoras, Clement, and Origen, was the centre of the Christian philosophy. Plato was regarded by all the Greeks of Alexandria as the master of wisdom, the interpreter of the divinity. If the first Christians had not embraced the dogmas of Plato, they would never have had any philosophers, any man of mind in their party. I set aside inspiration and grace which are above all philosophy, and speak only of the ordinary course of human events. It is said that it was principally in the "Timæus" of Plato that the Greek fathers were instructed. This "Timæus" passes for the most sublime work of all ancient philosophy. It is almost the only one which Dacier has not translated, and I think the reason is, because he did not understand it, and that he feared to discover to clear-sighted readers the face of this Greek divinity, who is only adored because he is veiled. Plato, in this fine dialogue, commences by introducing an Egyptian priest, who teaches Solon the ancient history of the city of Athens, which was preserved faithfully for nine thousand years in the archives of Egypt. Athens, says the priest, was once the finest city of Greece, and the most renowned in the world for the arts of war and peace. She alone resisted the warriors of the famous island Atlantis, who came in innumerable vessels to subjugate a great part of Europe and Asia. Athens had the glory of freeing so many vanquished people, and of preserving Egypt from the servitude which menaced us. But after this illustrious victory and service rendered to mankind, a frightful earthquake in twenty-four hours swallowed the territory of Athens, and all the great island of Atlantis. This island is now only a vast sea, which the ruins of this ancient world and the slime mixed with its waters rendered unnavigable. This is what the priest relates to Solon: and such is the manner in which Plato prepares to explain to us subsequently, the formation of the soul, the operations of the "Word," and his trinity. It is not physically impossible that there might be an island Atlantis, which had not existed for nine thousand years, and which perished by an earthquake, like Herculaneum and so many other cities; but our priest, in adding that the sea which washes Mount Atlas is inaccessible to vessels, renders the history a little suspicious. It may be, after all, that since Solon--that is to say, in the course of three thousand years--vessels have dispersed the slime of the ancient island Atlantis and rendered the sea navigable; but it is still surprising that he should prepare by this island to speak of the "Word."
