Coornhert, an engraver, and a partner of Van Zuyren, repeats the same statements, and on the same basis, in the preface to a translation of Cicero which he published in 1561, but is acute enough to see that the case for Haarlem is nearly hopeless. "I am aware," he says, "that in consequence of the blameable neglect of our ancestors, the common opinion that this art was invented at Mentz is now firmly established, that it is in vain to hope to change it, even by the best evidence and the most irrefragable proof." He proceeds to declare his conviction of the justice of Haarlem's claim, because of "the faithful testimonies of men alike respectable from their age and authority, who not only have often told me of the family of the inventor, and of his name and surname, but have even described to me the rude manner of printing first used, and pointed out to me with their fingers the abode of the first printer. And therefore, not because I am jealous of the glory of others, but because I love truth, and desire to pay all tribute to the honour of our city which is justly her due, I have thought it incumbent upon me to mention these things." Yet it is strange that he did not think it incumbent upon him to mention the name and surname of the inventor, since he had been told them so often. Hadrian Junius, said to have been the most learned man in Holland after Erasmus, is the first to give to the world the fully-developed legend of Coster. This he does in his _Batavia_, which was finished in 1568 and published posthumously twenty years later. It is he who first mentions Coster by name, and gives the story of the walk in the woods. He relates how Coster devised block-printing, and calling in the help of his son-in-law, Thomas Peter, produced the block-book _Speculum Humanæ Salvationis_, and then advanced to types of wood, then to types of lead, and finally to types of lead and tin combined. Prospering in his new art, he engaged numerous workmen, one of whom, probably named Johann Faust, as soon as he had mastered the process of printing and of casting type, stole his master's types and other apparatus one Christmas Eve, and fled to Amsterdam, thence to Cologne, and finally to Mentz. For all this Junius also adduces no better authority than hearsay, but nevertheless it is his statements which have brought Coster to the front and given him such reputation as he now enjoys. No books bearing Coster's name are known, though this in itself is no argument against him, for the name of Gutenberg himself is not found in any of his own productions. It is not only highly improbable that Coster was the first printer, but also doubtful whether he printed anything at all. But those who think otherwise consider that the idea of printing occurred to him about 1428 or 1430, and that he executed, among other books, the _Biblia Pauperum_, the _Speculum_, the _Ars Moriendi_, and _Donatus_.
