A progression similar to that which took place in Greek writing, distinguishes manuscripts in the Latin language, and affords a like criterion of antiquity. Several manuscripts believed, on good evidence, to belong to the third and fourth centuries, are extant, which present a style of writing nearly allied to that which appears in the inscriptions of the same period. But the uncial character gave place to the small letter at an earlier date among the Roman, than among the Greek copyists; yet they seem to have availed themselves of the change in a much less degree for the purposes of celerity. Indeed, there is little more of continuity, or of abbreviation in the small, than in the large character. Towards the tenth century the Latin scribes adopted a square and heavy character, similar to that which is seen in legal documents. This wide and full-faced letter was so much exaggerated by the writers of the fourteenth century, as almost to blacken the page with its massiveness. Still, a handsome regularity and a fair degree of legibility were maintained. There are, indeed, some manuscripts of this period extant which, for mathematical exactness and beauty, might almost challenge comparison with printed books. Nothing less, it is obvious, than a long-continued and extensive examination of ancient manuscripts, can confer upon any one such a degree of skill in discriminations of this kind, as might warrant his giving an opinion in a case of difficulty. Yet the mere inspection of a small number of these relics of antiquity may convince any one of the reality and distinctness of those progressive changes in the modes of writing upon which such discriminations are founded. The architecture of different periods is not more characteristic of the age to which it belongs, than is the style of writing in manuscripts; nor is there less certainty in determining questions of antiquity in the one case, than in the other. Particular instances may perplex or deceive the best-informed and the most acute observers; but the greater number of cases admit of no question. FORM OF ANCIENT BOOKS, AND THEIR ILLUMINATIONS. The mode of compacting the sheets of their books remained the same among the Greeks during a long course of time: little, therefore, pertinent to our argument, is to be gathered on this head. The sheets were folded three or four together, and separately stitched: these parcels were then connected nearly in the same mode as is at present practised. Books were covered with linen, silk, or leather.
