This set me down a rabbit hole. I just looked at every page of the voynich and I can't see it being woman's secrets. As the author of the paper says, the longest suspected encrypted document of woman's secrets would be a maximum of six pages if it was even ever encrypted. The thing is, anything that could be said about the topic back then couldnt possibly be stretched to so many pages. Also, the drawings of the women have basically no anatomical meaning (there are no clear drawings of anatomy, or of child birth, or of any medical procedure). The drawings of the women are extremely repetitive. I can't see how information can really be encoded in them. If the tubes and such are supposed to somehow be symbolic anatomical clues, the repetitive women posing a hundred times on the page are not needed.

One thing struck me the whole time looking at those pictures: they are extemely ugly, the author couldn't draw for shit. It literally looks like how i would draw if i was trying to make something look deep and metaphorical, but didn't really have any meaning to it. There's a lot of "symmetry" and repetition in the pictures that don't seem to possibly encode information.

Then again, some illustrations are made with such detail, that it seems unlikely they aren't.
