 6º The script of the book uses totally unknown glyphs, ergo it must be a system to link the stars with the plants using magical characters, although the authors believe or not in them. It can be just a game.

Only a few of the glyphs are unknown (t, p, and their benched versions). The rest of the glyphs are known and most of them are quite common.
