Het Nieuw Testament Antwerpen, Willem Vorsterman, 20 Sept. 1529 [NK 396-NAT V, II]
As far as the number of editions they printed is concerned, Willem Vorsterman and Michiel Hillen van Hoochstraten are the most important printers of the period being considered here. Vorsterman, extremely active between 1505 /6-1543 as a printer, book-dealer and publisher, was a man with international connections. From a cursory examination of the list of some four hundred known printed editions by him it is apparent that he printed a bit of everything in all the most important languages of his time: religious literature alongside chapbooks, school books and elevated tracts, official communications and suspect literature; even music. For if in the eyes of the world he was a good business man and cautious Catholic - printing as it seemed nothing but decrees and anti-Luther writings, and seldom venturing to print such ambiguous authors as Erasmus - in secret he printed numerous Lutheran texts.
