X-radiograph(s) of "Saskia" 

Editor: This is an X-radiograph of "Saskia," by Rembrandt. It's fascinating to see the inner layers of a painting. What does this reveal about Rembrandt's process? Curator: Observe the contrasting densities. These variations suggest multiple layers of paint application, revealing pentimenti, or alterations made by the artist. The composition, therefore, isn't a singular act, but a series of decisions etched into the material. Editor: So, the physical structure tells a story? Curator: Precisely. The X-ray unveils the evolution of Rembrandt's artistic vision, layer by layer. Editor: It’s like reverse archaeology. I see what you mean. Curator: Indeed. Examining the structure transforms our understanding.
