Whatever the division chosen, there are two alternatives: either the documents to be placed in this division are dated or they are not.
If they are dated, as is the case, for example, with the charters issued from the chancery of a prince, care will have been taken to place at the head of each slip the date (expressed in modern reckoning) of the document entered upon it. Nothing is then easier than to group in chronological order all the slips, that is, all the documents, which have been collected. The rule is to use chronological classification whenever possible. There is only one difficulty, and that is of a practical order. Even in the most favourable circumstances some of the documents will have accidentally lost their dates; these dates the compiler is bound to restore, or at least to attempt to restore; long and patient research is necessary for the purpose.
If the documents are not dated, a choice must be made between the alphabetical, the geographical, and the systematic order. The history of the Corpus of Latin inscriptions bears witness to the difficulty of this choice. "The arrangement according to date was impossible, seeing that most of the inscriptions are not dated. From the time of Smetius it was usual to divide them into classes, that is, a distinction was made, resting solely on the contents of the inscription, and having no regard to their place of origin, between religious, sepulchral, military, and poetical inscriptions, those which have a public character, and those which only concern private persons, and so on. Boeckh, although he had preferred the geographical arrangement for his Corpus Inscriptionum Græcarum, was of opinion that the arrangement by subjects, which had been hitherto employed, was the only possible one for a Latin Corpus...." [Even those who, in France, proposed the geographical arrangement] "wished to make an exception of texts relating to the general history of a country, certainly, at any rate, in the case of the Empire; in 1845 Zumpt defended a very complicated eclectic system of this kind. In 1847 Mommsen still rejected the geographical arrangement except for municipal inscriptions, and in 1852, when he published the Inscriptions of the Kingdom of Naples, he had not entirely changed his opinion. It was only on being charged by the Academy of Berlin with the publication of the Corpus Inscriptionum Latinarum, that, grown wise by experience, he rejected even the exceptions proposed by Egger in the case of the general history of a province, and thought it his duty to keep to the geographical arrangement pure and simple."[98] And yet, considering the nature of epigraphic documents, the arrangement according to place was the only rational one. This has been amply demonstrated for more than fifty years; but collectors of inscriptions did not come to an agreement on the subject till after two centuries of tentative efforts in different directions. For two centuries collections of Latin inscriptions have been made without any perception of the fact that "to group inscriptions according to their subjects is much the same thing as to publish an edition of Cicero in which his speeches, treatises, and letters should be cut up and the fragments arranged according to their subject-matter;" that "epigraphic monuments belonging to the same territory mutually explain each other when placed side by side;" and, lastly, that "while it is all but impossible to range in order of subject-matter a hundred thousand inscriptions nearly all of which belong to several categories; on the other hand, each monument has but one place, and a very definite place, in the geographical order."[99]
The alphabetical arrangement is very convenient when the chronological and geographical arrangements are unsuitable. There are documents, such as the sermons, the hymns, and the secular songs of the middle ages, which are not precisely dated or localised. They are arranged in the alphabetical order of their incipit—that is, the words with which they begin.[100]
The systematic order, or arrangement by subjects, is not to be recommended for the compilation of a Corpus or of regesta. It is always arbitrary, and leads to inevitable repetition and confusion. Besides, given collections arranged in chronological, geographical, or alphabetical order, nothing more than the addition of a good table of contents is needed to make them available for all the purposes which would be served by a systematic arrangement. One of the chief rules of the art of Corpus and regesta-making, that great art which has been carried to such perfection in the second half of the nineteenth century,[101] is to provide these collections, whatever the grouping adopted, with a variety of tables and indexes of a kind to facilitate the use of them: incipit tables in chronological regesta which lend themselves to such treatment, indexes of names and dates in regesta arranged by order of incipit, and so on.
Corpus and regesta-makers collect and classify for the use of others documents in which, at any rate in all of which, they have no direct interest, and are absorbed in this labour. Ordinary workers, on the other hand, only collect and classify materials useful for their individual studies. Hence certain differences arise. For example, the arrangement by subjects, on a predetermined system, which is so little to be recommended for great collections, often provides those who are composing monographs on their own account with a scheme of classification preferable to any other. But it will always be well to cultivate the mechanical habits of which professional compilers have learnt the value by experience: to write at the head of every slip its date, if there is occasion for it, and a heading[102] in any case; to multiply cross-references and indices; to keep a record, on a separate set of slips, of all the sources utilised, in order to avoid the danger of having to work a second time through materials already dealt with. The regular observance of these maxims goes a great way towards making scientific historical work easier and more solid. The possession of a well-arranged, though incomplete, collection of slips has enabled M. B. Hauréau to exhibit to the end of his life an undeniable mastery over the very special class of historical problems which he studied.[103]
CHAPTER V
CRITICAL SCHOLARSHIP AND SCHOLARS
The sum of the operations described in the preceding chapters (restoration of texts, investigation of authorship, collection and classification of verified documents) constitutes the vast domain of external criticism, or critical scholarship.
The public at large, with its vulgar and superficial standards, has nothing but disdain for the whole of critical scholarship. Some of its votaries, on the other hand, are inclined to exalt it unduly. But there is a happy medium between these extremes of over-appreciation and contempt.
