of Christ is on its right, and that of Moses on its left. A lute, from which three bells depend, lies across the eagle's breast; this is supposed to refer to the Marriage in Cana, and a little numeral tells us that the account of it is in the second chapter. Between the outspread claws is a bucket surmounted by a crown. These are symbolical of the Well of Samaria and the Nobleman's son at Capernaum in chapter iv. On the bend of the eagle's outspread right wing is a fish and the numeral 5, referring to the Pool of Bethesda in chapter v., and on the left wing are five barley loaves and two small fishes, and a small 6, referring to the parable of the loaves and fishes in the sixth chapter. This very singular book must have been a great favourite with the priests, and perhaps with the laity, for it was reprinted over and over again. It appears to have been of German origin.
Of the other block books mentioned in chapter ii. it would be tedious to give an account; they are very similar to those we have just described.
CHAPTER IV
SPECULUM HUMANÆ SALVATIONIS
Historians tell us that in the fourteenth and fifteenth centuries the cities of the Netherlands were the most populous and the richest in all Western Europe. Bruges, Ghent, Liège and Brussels by their manufactures, and Antwerp by her commerce, in which she rivalled Venice, had become celebrated for their great wealth, the grandeur of their rulers, and the magnificence of their great Guilds. The more northern towns, too, Amsterdam, Haarlem, and Utrecht, and many cities of Germany, such as Mentz, Cologne, Strasburg, Nürnberg, Augsburg, and Basel, were rich and prosperous. It was among these cities that the sister arts of printing and wood-engraving first flourished.
From undoubted evidence accumulated by the patience and labour of many bibliographers, it appears that the art of printing by means of movable type was not invented by any one man, but was the result of a gradual development of the art of engraving. In the fifteenth century, as in the nineteenth, there was an ever-growing demand for school books. One of the most popular of these in the fifteenth century was the 'Donatus,' a grammar so called from the name of the author. There was also a Latin Delectus called a 'Catho.' These were cheap books and were usually printed from engraved wood blocks. These and the block books already described were contemporary, and the immediate forerunners of separate types. (See Blades, 'Pentateuch of Printing,' p. 12.)
In certain editions of the 'Speculum' there are to be seen woodcuts printed in ink of one colour and text in ink of another colour, from metal movable types. These types are rude in the extreme, far more so than the German Indulgence of 1454, the very earliest known dated piece of printing. There is no doubt that the Donatuses were at first printed from wood blocks, both in Germany and the Low Countries, but there is not a single Dutch block-book Donatus known, while there are some nineteen or twenty early type-printed Dutch Donatuses already catalogued. Therefore it appears likely that Gutenberg simply developed the process which had already been for some time in use in the Low Countries for Donatuses and similar books.
