f67r1 and the supposed constellations

[Anton]

That's a very interesting idea, but obviously there are a few catches. The zodiac names could be abbreviated in different ways, for example.

Worse, if the 'encryption' method is verbose, this will not work at all.....

Finally, I am not that sure that any herbals from the same time frame mention one zodiac sign in each of their descriptions / recipes....

Yes, of course. That's just an idea inspired by a passing observation (which may be a missed shot altogether).
