X-radiograph(s) of "Annonciation" 

Editor: This is an X-radiograph of an anonymous painting titled "Annonciation" from the Harvard Art Museums. It's fascinating to see the underlayers like this. What can we learn from its composition using this technology? Curator: The stark contrast reveals the artist's process—the pentimenti, or changes made during painting. Observe the density and line; they betray the materiality of the paint itself. Can you identify any areas where the artist reworked a form? Editor: It seems like the angel's robe on the left has been altered; the lines are much heavier there. Curator: Precisely. These visual cues offer insight into the artist's aesthetic decisions and the structural development of the artwork. The radiographic perspective really allows us to deconstruct artistic methodology. Editor: I hadn’t considered seeing the creative process itself as part of the artwork's structure. Thanks for pointing that out.
