The Voynich Manuscript as an Iberian-African Voyage Record

[Kaybo]

I do joke with potential solvers sometimes "numbers!", as for some reason they think anything that can work must be right. List of numbers then..
There's no reason its not really, it would just be weird and probably not advance us in understanding (or be provable). Also as you say, if it is a cipher that uses a look-up book.. we are likely doomed without the book.

On the general line of thinking though, which seems to be reductionist, I think you may find this worthwhile to read - You are not allowed to view links. Register or Login to view.. It's at least good food for thought.

I tried to understand some parts of the text in your link, but I think if it is a rule...why there are exceptions? But its the same with the cz (ch), sometimes the writer puts a dot (or something) on top of it and sometimes not. 

If it was right, we wouldn't still be here talking about the mystery of the VM. But there is a lot to be learned from what has not succeeded so far.
If I could give any advice to newer people, it would be to learn from what has been done so far because years of knowledge can be absorbed in a night or two even if it seems flawed.

Thats absolut true. Do you think I can make a question thread? Because I think it will be nearly impossible to read everything here, because its very difficult to sort the useful from the not useful content. For example I tried to read the curated threads, but it often misses the information I am looking for. Like the best attempts of encryption or interpretations, even if they fail, that could have some valuable hints, but a lot are so far off, that I dont even understand what they are talking about. I also want to read this letters everyone is talking about. Is there an englisch translation?
