The paintings are 500 years old but look like photographic portraits, down to the individual hairs in the stubble on More's chin. Realism was in vogue at the time but there weren't many other artists who were as good as Hans Holbein.

No disagreement about the excellent art.
But even setting aside any of that, it's pretty rare that I see a portrait that old and I think it could conceivably be recent.

You can substitute "photorealistic" with "looks like the square (or rectangle) picture in the mirror".
Turns out photographic pictures did capture that "image in the mirror" picture. Funnily enough, using... Mirrors.
> ... or the photos that were painterly?
The answer is simply no. The real world doesn't work like that: photons/mirrors/prisms/our eyes "capturing" photons. Physics vs dialectic if you want.
Reflections in the mirror have depth and motion. Even without the viewer or the subject moving, the viewer can see depth in the mirror that isn't in a photo. In those respects, photos are more like paintings than mirrors. Of course, in other respects, they're more like mirrors.
