No text, but a visual code

[Antonio García Jiménez]

There are two powerful reasons to think that we are facing a book with a magical component:

First, we see above all stars and herbs and a weird script whose function seems to be to channel the hidden powers of the stars to the herbs. It's like a spell.

And second, no equal document has survived, which is very rare and leads us to think that other identical books ended up at the stake of the inquisitors.
