The allusions to letter-cutting that are so frequent in all the earlier notices of type-making can be readily explained. The cutting is not that of types used for printing, but of the punches by which the printing types were made. The types of the early printers were made by two classes of workmen: he who poured the melted metal was the founder; he who made the model letters was the cutter. Performing the more artistic and the more difficult part of the work, the punch-cutter was properly regarded as the maker of the types. The variety of faces in the types of the unknown printer can be explained in a much more satisfactory manner than by attributing them to the accidental slips or deviation of the graving tool. The letters of the manuscript books of that century were not uniform; it was not necessary that printed letters should be uniform. The fashion of the day did not require it. On the contrary, it did seem desirable that the letters should be printed with the variety of shapes to which readers were accustomed. Whether this variety of shape in [p299] type was the result of design, of accident, or of necessity need not now be considered; in this place it is enough to say that all the early printers made many varieties of the letters which they most frequently used.[154] It should, however, be noticed that this apparent taste for variety of form was confined to the small or lower-case letters. Two forms of a capital letter are rarely found in the same book, but the same form of capital is occasionally used with two faces of lower-case types that are decidedly different.
