X-radiograph(s) of "St. John and Donor" 

Editor: This is an X-radiograph of "St. John and Donor" by the School of Jan Provoost. It's fascinating to see the layers beneath the surface. What structural elements do you find most compelling? Curator: The composition is, of course, dictated by the original painting. However, the X-ray reveals the artist's process—the underdrawing, the pentimenti, the adjustments made to the forms. Do you observe any specific instances of these compositional changes? Editor: I think I see some alterations around the head of St. John. It’s like a ghostly echo. What does that imply about the artist's intention? Curator: Precisely. These adjustments speak to the artist's evolving vision. The changes in line and form, visible only through this technology, reveal the artist grappling with representation and idealization. Editor: So, the X-ray isn’t just a technical tool, but also a window into the artist's mind. Curator: Indeed. It allows us to analyze the artist's formal decisions on a deeper level and better understand the evolution of the composition. It also underscores the complex relationship between the visible and the invisible in art.
