X-radiograph(s) of "Annunciation" 

Editor: Here we have an X-radiograph of "Annunciation" by Petrus Christus. The composition is so striking in its abstract quality. What stands out to you in this image? Curator: The stark interplay of light and shadow immediately commands attention. The grid-like structure imposed upon the underpainting creates a fascinating tension between representation and abstraction. Consider the materiality of the X-ray itself, and how that informs our reading. Editor: So, the grid emphasizes the layers beneath the surface? Curator: Precisely. It's a meta-commentary, perhaps, on the very act of seeing and the hidden structures that underpin artistic creation. Note the density of certain areas—what might those variations in opacity suggest? Editor: I see what you mean. It's like a hidden architecture. Curator: Indeed. This image certainly invites us to reconsider how we perceive not just this painting, but art itself. Editor: I've never thought about it that way. Thanks!
