A full notice of the details of early printing might have been considered out of place in the preface to a classic text book, but it would have been pertinent in a “_Dialogue on the First Invention of the Typographic Art_,” which was the title of a book said to have been written by Jan Van Zuren. Of [p328] this dialogue nothing is known but the introduction. Whether the author grew weary of his task, and abandoned it before completion, or whether the manuscript was destroyed, as is alleged, during the siege of Haarlem in 1573, cannot now be ascertained. All we know of this manuscript is through Peter Scriverius, who, diligently gleaning every scrap of history that favors the Haarlem invention, has preserved the preface. It is too long and rambling for a literal translation; this is the substance, which Van Zuren approached with great delicacy: He does not wish to deprive Mentz of its rightful honors, but he will see that the honors of Haarlem are not altogether lost. The town of Mentz, so justly lauded, first introduced this art, received from us, in public life. The first crude foundations of this excellent art were laid in our town of Haarlem. Here the art of printing was born. No doubt it was here carefully cultivated and improved; here it remained during many years, until at last it accompanied a foreigner and made, at last, its public appearance at Mentz. Here again is a noticeable absence of names, dates, books, evidences and authorities.[184] From beginning to end there is nothing in this statement but naked assertion. One fact of real value may be gleaned from the preface of Van Zuren and the dedication of Coornhert. There was even then in Haarlem a strong prejudice against Mentz; there was a wavering belief among some of the townsfolk that printing had been invented in Haarlem, and that the pretension of [p329] Mentz was unfounded. Whether this prejudice had been fostered by the obscure language of Zell, or whether it took its rise in the conceit of the simple people of the town, who may have thought that Ballaert, the first printer at Haarlem, was also the first printer in the world, cannot now be ascertained. There was a prejudice, and Van Zuren and Coornhert thought that it would be to their interest as printers to propitiate it. The publication of these mysterious allusions to an early printer in Haarlem strengthened the belief of Hollanders in the legend. It was imposed as veritable history on intelligent foreigners who were unable to disprove it. Luigi Guicciardini, a Florentine nobleman, for many years resident of Antwerp, and who there wrote and published, in 1567, a _Description of the Low Countries_, was the first author of distinction who gave a world-wide publicity to the legend. In his book he says:
