Johannes von Valkenburg was a Franciscan monk of the Friars Minor in Cologne, a calligrapher and illustrator.
He is known for having written, decorated and illustrated a manuscript for the Franciscan monastery in Cologne at the end of the 13th century and for having made two copies of it. One is in the Archdiocesan Diocesan and Cathedral Library in Cologne, the other in the University and State Library in Bonn. On the title pages of these rarities is an inscription indicating Valkenburg's authorship.
Herri met de Bles is a Flemish artist, along with Joachim Patinir, one of the founders of European landscape painting. He painted mainly landscapes with multi-figured compositions. Like Patinir, his style is characterized by stylized images of rocks and a careful rendering of aerial perspective.
