X-radiograph(s) of "Philip IV (copy)" 

Curator: This X-radiograph unveils a copy of Diego Velázquez's portrait of Philip IV. The stark contrast of the image gives it an almost ghostly quality. Editor: It's fascinating to see the physical layers beneath the visible surface. The process reveals the artist's hand and the material build-up. Were x-radiographs common at the time of this copy? Curator: X-radiography, though not as advanced, certainly offered a glimpse into earlier painting techniques. It was beginning to gain traction in conservation and art historical study. Understanding its purpose in the creation of this copy could unveil much about the copyist's intentions. Editor: Indeed. The materiality of the original, the pigments and ground layers, would inform the subsequent labor. Perhaps a closer study can discern the artist's material choices and techniques. Curator: Exactly. Perhaps through the X-ray, we can better grasp the socio-political forces that spurred this act of imitation and dissemination of the royal image. Editor: It gives a whole new dimension to the term "underpainting."
