The name of the artist by whom those letters were engraved is unknown. In Sebastian Munster’s Cosmography, book iii. chapter 159, John Meydenbach is mentioned as being one of Gutemberg’s assistants; and an anonymous writer in Serarius states the same fact. Heineken in noticing these two passages writes to the following effect. “This Meydenbach is doubtless the same person who proceeded with Gutemberg from Strasburg to Mentz in 1444.[IV-2] It is probable that he was a wood engraver or an illuminator, but this is not certain; and it is still more uncertain that this person engraved the cuts in a book entitled _Apocalipsis cum figuris_, printed at Strasburg in 1502, because these are copied from the cuts in the Apocalypse engraved and printed by Albert Durer at Nuremberg. Whether this copyist was the _Jacobus Meydenbach_ who printed books at Mentz in 1491,[IV-3] or he was some other engraver, I have not been able to determine.”[IV-4] [Footnote IV-2: Heineken in his Nachrichten, T. I. S. 108, also states that Meydenbach came from Strasburg with Gutemberg. Oberlin however observes, “Je ne sais où de Heinecke a trouvè que ce Meydenbach est venu en 1444 avec Gutenberg à Mayence.” Heineken says, “In der Nachricht von Strassburg findet man dass ein gewisser Meydenbach 1444 nach Maynz gezogen,” and refers to Fournier, p. 40. Dissert sur l’Orig. de l’Imprimerie primitive.] [Footnote IV-3: An edition of the Hortus Sanitatis with wood-cuts was printed at Mentz, by _Jacobus Meydenbach_, in 1491.] [Footnote IV-4: Idée Générale, p. 286.]
