1437 After prolonged experiment, he abandoned this method. 1438 He invented a method of casting types of lead. 1439 He began to print an edition of the _Donatus_, and the Dutch edition of the _Speculum_. In this year Gutenberg took service with Coster, and began to print for him, by which he earned the title of the Book-printer of Haarlem. (!) 1440 Gutenberg absconded with some knowledge of the invention. He was able to cut, but not to cast types. (!) 1441 He established a printing office in Mentz. 1442 Gutenberg printed an _A b c_ book, the _Doctrinal_ of Alexander Gallus and the _Treatise_ of Peter of Spain. By this time Coster had repaired the damages of the theft. 1443 Coster printed the second edition of the _Speculum_ in Dutch. 1444 Coster printed a Latin edition of the _Speculum_. 1446 Gutenberg also induced Gensfleisch, called afterward Faust, (!) and Meydenbach to join him in printing a _Latin Bible_. 1457 Coster’s art was well known, and excited the envy of the Archbishop of Canterbury and of King Henry VI of England. 1457 The Archbishop persuaded the king to get a knowledge of the art from Gutenberg, the first book printer of Haarlem. (!) 1459 Turnour and Caxton, who were sent on this mission, bribed Frederick Corsellis, a workman of Coster, to run away from Haarlem in disguise. To prevent his escape, Corsellis was taken to Oxford, in which town he began to print in 1468. 1467 Coster died, about the same time that Gutenberg and Faust died. (!) His printing office ceased to exist.[208] Seiz has not told us where he obtained this curious information, but we shall make no mistake if we attribute it to an imagination disordered by national pride. His chronology is so absurd that serious criticism would be a waste of time. Notwithstanding the strong efforts of Seiz to remove the impression created by the contradictory accounts of his predecessors, the citizens of Haarlem seemed to be involved in [p353] greater doubts than ever about the chronology of the invention. For, in 1740, upon the occasion of the third jubilee of Coster’s invention, two silver medals were struck, with legends curiously unlike. We here see that the name of the inventor is printed in different forms; one medal bears the date 1440, and the other contains the date 1428. These irregularities prepare us for what is to follow. [Illustration: Medals in Honor of Coster. [From Seiz.]] In 1757, Gerard Meerman, subsequently a distinguished champion of the Haarlem legend, wrote “that the pretentious assertion of the invention of printing by Laurens Coster begins to lose credit more and more. The particulars that have been related by Seiz are mere suppositions, and the chronology of Coster’s invention and enterprise is a romantic fiction.”
