5. As the New Testament far surpasses all other remains of antiquity in value and interest, so are the copies of it yet existing in manuscript and dating from the fourth century of our era downwards, far more numerous than those of the most celebrated writers of Greece or Rome. Such as have been already discovered and set down in catalogues are hardly fewer than three thousand six hundred, and more must still linger unknown in the monastic libraries of the East. On the other hand, manuscripts of the most illustrious classic poets and philosophers are far rarer and comparatively modern. We have no complete copy of Homer himself prior to the thirteenth century, though some considerable fragments have been recently brought to light which may plausibly be assigned to the fifth century; while more than one work of high and deserved repute has been preserved to our times only in a single copy. Now the experience we gain from a critical examination of the few classical manuscripts that survive should make us thankful for the quality and abundance of those of the New Testament. These last present us with a vast and almost inexhaustible supply of materials for tracing the history, and upholding (at least within certain limits) the purity of the sacred text: every copy, if used diligently and with judgement, will contribute somewhat to these ends. So far is the copiousness of our stores from causing doubt or perplexity to the genuine student of Holy Scripture, that it leads him to recognize the more fully its general integrity in the midst of partial variation. What would the thoughtful reader of Aeschylus give for the like guidance through the obscurities which vex his patience, and mar his enjoyment of that sublime poet? 6. In regard to modern works, it is fortunate that the art of printing has wellnigh superseded the use of _verbal_ or (as it has been termed) _Textual_ criticism. When a book once issues from the press, its author’s words are for the most part fixed, beyond all danger of change; graven as with an iron pen upon the rock for ever. Yet even in modern times, as in the case of Barrow’s posthumous works and Pepys’s Diary and Lord Clarendon’s History of the Rebellion, it has been occasionally found necessary to correct or enlarge the early editions, from the original autographs, where they have been preserved. The text of some of our older English writers (Beaumont and Fletcher’s plays are a notable instance) would doubtless have been much improved by the same process, had it been possible; but the criticism of Shakespeare’s dramas is perhaps the most delicate and difficult problem in the whole history of literature since that great genius was so strangely contemptuous of the praise of posterity, that even of the few plays that were published in his lifetime the text seems but a gathering from the scraps of their respective parts which had been negligently copied out for the use of the actors.
