This may be rendered: The present historical work has been printed and completed in the year of the Lord 1515, on the vigil of Margaret, virgin, in the noble and famous city of Mainz, first inventress of this printing art, by John Schöffer, grandson of a late worthy man, John Fust, citizen of Mainz, foremost author of the said art, who in due course by his own genius began to think out and investigate the art of printing in the year of the Lord’s nativity 1450, in the thirteenth indiction, in the reign of the most illustrious Emperor of the Romans Frederick III, and when the most reverend father in Christ, Theoderic the cup-bearer, of Erbach, prince-elector, was presiding over the sacred see of Mainz, And in the year 1452 perfected and by the favor of divine grace brought it to the work of printing, by the help, however, and with many necessary inventions[2] of Peter Schöffer of Gernsheim, his workman and adoptive son, to whom also he gave his daughter Christina Fust in marriage as a worthy reward of his labors and many inventions.[2] And these two already named, Ioannes Fust and Peter Schöffer, kept this art secret, all their workmen and servants being bound by an oath not in any way to reveal it; but at last, from the year of the Lord 1462, through these same servants being spread abroad into divers parts of the world, it received no small increase.
