Well as the other poster commented: there are many editions of this book and they were kinda mass-printed. I've got an "original" one as it is really from 1575

Well as the other poster commented: there are many editions of this book and they were kinda mass-printed. I've got an "original" one as it is really from 1575 but the author died in 1566. The version I have is in old french and, yup, some people did put actual physical plants pressed between the page!
