X-radiograph(s) of "Mrs. Alexander MacWhorter" 

Editor: This is an X-radiograph of “Mrs. Alexander MacWhorter” by John Singleton Copley, currently held at the Harvard Art Museums. The ghostly image is fascinating. What can we learn about Copley’s process by studying this? Curator: The X-radiograph allows us to analyze the painting’s underlying structure. Notice how the density of the white areas reveals the application of lead white pigment. Can you discern any patterns or changes in the composition? Editor: It looks like there are subtle differences in brushwork and perhaps even some pentimenti in the face. What does that suggest about Copley’s methodology? Curator: Precisely. These pentimenti offer insight into his evolving artistic intentions. They demonstrate a process of refinement, revealing how Copley adjusted forms and proportions to achieve his desired effect. This close reading enhances our understanding of his formal decisions. Editor: That's a great observation. I see so much more by looking at it this way.
