X-radiograph(s) of "St. Christopher (triptych)" 

Editor: This is an X-radiograph of "St. Christopher (triptych)" by Hans Memling. It's fascinating to see this almost ghostly version of the artwork. What does this reveal about the painting's composition and structure? Curator: The radiograph unveils the artist's process. Notice how the density variations suggest layered applications of pigment. The brighter areas indicate heavier elements like lead white, used to create highlights and volume. Editor: So, it's like seeing the skeleton of the painting? Curator: Precisely. We're observing the armature, the underlying structure that gives form to the visible surface. Consider the implications for our understanding of Memling's technique. Editor: It’s amazing how much a simple radiograph can tell us about the painting’s creation! Curator: Indeed. By analyzing such formal elements, we gain insight into the artist's methodology and the evolution of the artwork itself.
