I want to do a project where I create a fake 'archeological discovery' illustrated/illuminated manuscript. So I'm trying to find source images of good art styles, but I don't know of a good term to describe the kind of art I'm looking for, so it's making it very hard to google. I want art which is representational but heavily stylized or symbolic. I'd prefer art which has words or other written symbols within the image, not separated like in modern word bubbles/captions. I don't care when or where it was created. It's ok if the proportions or perspective are wonky, like the way eyes are drawn in Egyptian murals, or the way some Art Nouveau work gives people tiny hands and feet and really long necks.

So, can anyone recommend either a term I can google or some specific photobooks or artists I should look at?

For reference, here is a page of the Voynich manuscript and one from the Egyptian Book of the Dead:
