# Mirror anamorphosis for Escher's Circle Limit engravings?

You are probably familiar with "mirror anamorphosis," the rendering in a painting of a distorted figure that can be undistorted by viewing in an appropriately tilted or curved mirror. The skull in the Hans Holbein painting (the streak at bottom center) is perhaps the most famous example:

My question is: Is there a mirror which "undistorts" an Escher Circle Limit engraving? Here is Circle Limit IV:

"Undistorting" would render the angels and devils the same size, off to $\infty$. The figures would still shrink in distance, but as if they were on a plane, rather than in the Poincaré disk. In other words, the mirror view would give the illusion that the figures are on a plane.

Well, you know that the Euclidean and the hyperbolic planes are not conformally equivalent, so it’s not clear to me what you’re asking. When you say “render the angels and devils the same size, off to $\infty$”, you aren’t asking for them to appear to the viewer as if they lie on a plane in such a way that they’re the same size on the plane, are you?
