Graeca capta ferum victorem cepit et artes Intulit agresti Latio. Greek culture had become so widespread that a sojourn in Athens was no longer necessary for those who were ambitious to learn the language in its purest form. Though this city was still looked upon with a certain filial regard, half a score of rivals had sprung up in three continents that at times seriously threatened its prestige. The centuries that meet at the birth of Christ are the link that unites the golden age of Greek literature with the Renaissance. In them was coined much of the small change of Greek thought, which was by reason of its form the more widely circulated. That much of it was silver, so to speak, only made it the more generally available. But while the writings of these three or four centuries have suffered greatly from neglect at the hands of the moderns, the language in its narrower sense, except that of the New Testament, has been almost wholly ignored. It needs but a brief examination of the current Greek dictionaries to convince the student that here is an ample field for profitable work. Even the great Thesaurus of Stephanus often leaves one sadly in the lurch; besides, it is both too extensive and too expensive for general use. What we need is a careful lexicographical and grammatical study of the individual authors and the presentation of the results in as succinct a form as possible. It is a pleasure to note the signs of a revival in this quarter—for that it is not a misnomer to speak of a revival will be evident to those who know that the reader of some of the authors above named, together with others, is largely compelled to rely on texts that are more than half a century old, in some cases much more. In this laudable work of rediscovery, Professor Mahaffy in Great Britain, and Professor Krumbacher in Germany, may be regarded as the leaders. The former, by his various works upon the Greeks under Roman sway, and the latter by his masterly _Geschichte der Byzantinischen Litteratur_ and his _Byzantinische Zeitschrift_ have done more than any two writers in the present century to awaken an interest in a subject that has long been in a comatose condition. The present volume, though bearing upon the general theme, is concerned with but a small portion of it. I have tried to throw a little light upon two authors, in whose writings are many passages that put them in some sort of relation to nascent Christianity. While it is almost absolutely certain that neither Seneca nor Plutarch had any knowledge of the new doctrines first preached in their time, it ought surely to be a matter of interest to every thinking man to note how closely the best that is in the old philosophy approached the new religion; or, to state the case somewhat differently, that the old philosophy and the new religion are in many points identical.
