Ubiquity of Text-over-image in painting, to see this natural resolution is required
'Text-over-Image' approach was popular with most of the cultures most of the times for thousands years.
In our culture text-over-image is ignored and regarded as something archaic, and as result digital images regularly even do not provide quality to see or read such texts due to inadequate image resolution.
I would suggest that each image has its own adequate resolution making all important details visible, but not more than that. One can call it natural resolution.
When we have images with natural resolution, we can find text over image much more often that we can image.
Here is one example:
Look at this Renaissance dated paintings of “The Last Supper”.
At first sight obviously there is no text over this image.
But when you look at this zoomed image of a detail of this painting (you need to click on it) – you can see that each apostle is named, but Judah.
Naming is equivalent of bringing object to a viewer or to eternity or both, as if they are the same.
Everything important to paint is important to name.
