Main (Thompson) Library location: South wing -- Third window. Early records first locate Johannes Veldener (v) in the diocese of Würzburg. By 1473 he moved to Louvain, where he matriculated at the University to study medicine. Scholars believe that he studied printing in Cologne, but the timeline for this remains unknown. The first book attributed to Veldener is an undated edition of Lis Belial by Jacobus de Teramo, printed in Louvain. As a result of the France-Habsburg conflict rattling Louvain in 1477, he transferred to Utrecht, where he worked until 1481. Later, Veldener moved to Culemborg to seek refuge from the same conflict. The titles of his publications include Dat speghel onser behoudenisse, Valuacie van den gelde, St. Jerome's Speculum valde horribile, and Boccaccio's Genealogiae deorum. The printer's mark of Johannes Veldener was one of the first to appear in Louvain in the late 15th century. As it appears in the Vassar Library, the mark consists of two heraldic shields suspended from a tree branch. The shield on the right displays the arms of Louvain – though Veldener modified the mark regularly to reflect the city of his current location. In other versions, Veldener's name appeared directly below the branch.
