Joking apart, I think it is a copy of a very rare document that had big value for the author as a real artefact, or, maybe, it relates to some secret place, etc. Quite possibly, the author was a traveller, he could find or buy some unusual ancient scroll or manuscript and decide to hide its contain in an 15c almost clear manuscript with a few pictures of plants.
Unfortunately, all these are just a couple of many possibilities.
