X-radiograph(s) of "Portrait of Marshall" Possibly 1 - 72

Editor: This is an X-radiograph of Thomas Sully’s "Portrait of Marshall." The ghostly, almost ethereal quality is striking. What can you tell me about what the visual qualities reveal? Curator: Observe how the density of the materials—pigments, canvas, and ground layers—react to the X-rays. The varying opacities offer insights into Sully's technique and material choices. Notice the brushwork and the layering of paint; these create depth. Editor: I see what you mean. It's like a map of the artist's process, revealing the structural decisions. Curator: Precisely. It's a fascinating intersection of art and science, offering a unique lens through which to understand artistic creation. Editor: This has certainly given me a new way to appreciate art. Thank you.
