"Marvels of delight. Master drawings from Jan van Eyck to Hieronymus Bosch" gave the public an opportunity to learn more about these late medieval artists and their sublime draughtsmanship. The story of almost one hundred years of drawings (ca. 1425–1510) by the Flemish Primitives is actually that of four master painters - Jan van Eyck, Rogier van der Weyden, Hugo van der Goes and Hieronymus Bosch - and the artists they inspired. Fifty drawings found their way to the Rubens House.
Rubens was a fan of Early Netherlandish drawings. He collected them and even retouched them here and there with some "creative interventions". With all the best intentions. He felt that they only improved the work.
