At the European level, Hans Memling is one of the most famous representatives of painting in the Low Countries before 1500. In his art, he builds on the achievements of his great predecessors Jan van Eyck and Rogier van der Weyden. This triptych with St Christopher is considered a key work in Memling’s oeuvre for several reasons. The central motif of the three standing saints is a rare composition in painting from the Low Countries. The landscape in the background of the three panels suggests one continuous space. In this respect, it is a milestone in the development of landscape painting, which did not develop into a separate genre until the beginning of the sixteenth century. The portraits reveal Memling’s great talent in individualising and idealising his models at the same time. This painting of Willem Moreel and his large family is one of the earliest and most impressive family portraits in the history of painting in the Southern Netherlands.
