THE SPECULUM SALUTIS.
269
The Speculum was printed at different times and places during the fifteenth century,[1] but the copies of greatest value are those which belong to four correlated editions—two in Latin, and two in Dutch—all without date, name, or place of printer. In these four editions the illustrations are obviously impressions from the same blocks; but each edition exhibits some new peculiarity in the shape or disposition of the letters. Those who favor the theory of an invention of typography in Holland maintain that these letters are the impressions of the first movable types, and that the curious workmanship of the book marks the development of printing at the great turning-point in its progress when it was passing from xylography to typography. As important conclusions have been drawn from the peculiarities of each edition, it is necessary that they should be described with precision. The order in which the four editions were actually printed is not certainly known. Six eminent bibliographers have arranged them in as many different orders. The order assigned to them here
- ↑ There is an edition, with a text in Latin and in German, which was printed at Augsburg in 1471; there are many editions in German only, some without dates, and others with dates of 1476, 1492, and 1500; a Flemish edition by Veldener in 1483; and various editions in French.
