Not specifically a direct Q research topic, but historically relevant and related nonetheless…
On a dog walk early this morning, I passed by a set of 4 discarded hard bound books with titles referencing Illuminated Manuscripts. At first my mind read, "Illuminati Manuscripts" and my eyes got all big. Flipping through them, I realized the topic was book illumination, the term used to describe the illustration method used on books of antiquity, dating before the development of the Gutenberg press book printing and reproduction.
Doing a bit of reading inside the books, I learned that the use of paper is relatively new. In fact, the development of paper was a carefully kept Chinese secret for centuries, until captive Chinese scribes revealed it to their Arab captors in 751 AD. In fact, book production methodology was carefully controlled by religious and political leaders. Ancient Egypt in particular was known for guarding the secrets of written text creation. Control of information then (as now) is part of the enslavement process.
Among the discovered benefits of using paper over previous methods of manuscript creation was the fact that with paper, it was not easy to erase/change text (dyes were absorbed deep within the paper instead of being painted over non-absorbent parchments) to suit the nefarious designs of an individual.
Also, take note that comp'd rulers and politicians attempting to hide written evidence of their misdeeds and criticisms goes way back. (((They))) have been doing this crap a long time.
An interesting Q related illumination is the early 8th century mapping of the Old and New Testament Bible books. That graphic method used for comprehending information is obviously very effective. I've included a large version for those wishing to see the details.
