As the case stands at present, after careful and impartial examination of all available evidence, no choice is left but to attribute the invention of printing with individual movable cast-metal type to Lourens Janszoon Coster of Haarlem in the Netherlands between the years 1440 and 1446 and not to Gutenberg of Mainz in Germany. Zell's statement in the "Cologne Chronicle" of 1499 is further substantiated by Hadrianus Junius in his "Batavia." Junius stated that printing from individual movable type was invented by Coster in Haarlem, and that the "Speculum Humanae Salvationes" was one of his first productions. These two statements were made independently of each other and both are corroborated by books to which they refer. The "Speculum Humanae Salvationes," attributed to Coster by Junius was partly a folio Latin block-book, and partly typographically printed. From this and other records it has been clearly established that Coster began as a xylographer and ended as a typographical printer, and before 1472 he had manufactured and extensively used at least seven different styles of primitive looking individual movable cast-metal type. According to tradition, while he was walking in a wood near Haarlem, Coster cut some letters in the bark of a beech tree, and with them, reversely impressed one by one on paper, he composed one or two lines as an example for the children of his son-in-law. Junius does not say it, but clearly implies that, in this way, Coster came to the idea of the movability of the characters, the first step in the invention of typography. He perceived the advantage and utility of such insulated characters, which hitherto he had been cutting together on one block, and so the invention of printing with individual movable type was made. The questions as to whether he continued to print with movable "wooden" type, or even printed books with them, cannot be answered, because no such books or fragments of them have come down to us. Junius' words on this point are ambiguous, and yet, upon the examination of the first edition of the Dutch Spiegel (of which two copies are preserved at Haarlem) no one would deny that there are grounds for this belief. The dancing condition of the lines and letters make it almost impossible to think that they are impressions from metal type. But for how long and to what extent movable wooden type were employed, if at all, cannot be positively stated. However, this idea of movability, and the accidental way in which it was discovered, form together the pith of the Haarlem tradition as told by Junius. Nothing seems more natural than that a block-printer should cut such separate letters as Coster did on the bark of a tree and thereupon perceive that they could be used over and over again for a variety of words on different pages, while those which he used to cut in a solid block only served him for one page and for one purpose.
