X-radiograph(s) of "Armed Angel Principatus" 

Editor: This is an x-radiograph of "Armed Angel Principatus," by Guariento di Arpo, at the Harvard Art Museums. Seeing it in grayscale, like this, almost feels like peering back in time. What secrets does this x-ray reveal to you? Curator: Ah, it’s like a ghostly echo, isn't it? The x-ray lets us see beneath the surface, quite literally! It reveals the artist's process, pentimenti, and the materials they used. Think of it as the artwork’s skeleton, showing its hidden structure. Are there areas that surprise you? Editor: Well, the halo seems very prominent. Is it made of different materials? Curator: Exactly! X-rays interact differently with various materials. The halo might contain denser pigments or even metallic leaf. It's like the artist placed special emphasis there, imbuing it with extra luminosity. It makes you wonder about the original intentions, doesn't it? Editor: It does. Thanks, I'll look at the actual painting differently now! Curator: My pleasure! It's always enlightening to see the art from a different angle.
