Rich, you are just playing with words, and your text was not a quote of mine.
Well I of course disagree on the first part, but as for the text not being a quote of yours... how would I know that? It is on your website, and I did "quote" your website. That is copied and pasted from your site. It is normal to assume, and is the usual case, that text on someone's site has been entered by themselves. Otherwise, the origin is cited.
But your words, or if you are quoting someone else, it does say "... the book production process is likely to have taken considerably less time than these 50-60 years", then "
under this assumption", this range was reduced to the far lower range of 1404-1438. If you disagree with such changes being based on that assumption, and being based on some other assumption or however you would phrase it, then maybe your official page on the subject ought to be changed.
I do have an earlier version of this statement, also from your site, up on my page of Modern Voynich Myths:
"The dating of each folio doesn’t allow a very precise dating of the MS. The uncertainty in age for each folio is some 50-60 years, and in the case of fol.68 even spans two centuries due to the above-mentioned inversions of the calibration curve. The book production process is likely to have taken considerably less time than these 50-60 years. Under the assumptions that:
– The MS was indeed created over a time span not exceeding (e.g.) 10 years
– It was not using parchment that was prepared many years ago
each sheet provides a measurement or ‘observation’ of the MS creation. Since they are likely to be from different animal hides, these are indeed independent observations. Combining these observations leads to a combined un-calibrated age of 1435 ± 26 years (1 sigma).”
Again, I assumed that this was your statement, and not by anyone else. But if it was not yours, then I would be curious by whom it was said? And also, why it was later modified, into the statement I used here, and by whom, if not you? I note the assumption of "The MS as indeed created over a time span not exceeding (e.g.) 10 years" was removed. But here is the thing about that: The removal of that claim is one thing, but the data was, by then, processed, and the timeline shortened. So we already know this 10 year assumption was in effect... I mean, we can't go back and change the reasons we did things in the past. We did them a way for a reason, and changing the report of that cannot change that reason.

Then why process this raw data at all, if it makes no difference? There is a lot of effort... this is like a real "hot button issue", obviously. Why? And it of course does not define the Voynich as a forgery in and of itself, but it is a valuable bit of information to know this. It is a "brick in the wall" of the real picture of what the Voynich might be: If it were made from sheets of parchment of varied age, we would want to know why that was done. Furthermore, it should be of great interest to know, even if the Voynich turns out to be genuine: Perhaps, off the top of my head, causing some researcher to limit their search for an origin to those places where scribes might have access to materials half a century apart. Who knows?
But I would suspect the reason this was done, why the processed lower range is the one projected, is exactly because it is a problem. To my knowledge, manuscripts are simply not made this way, from leaves from many ages, over half a century apart. It is common sense to realize it opens the possibility that a forger had access to a varied collection of old blank vellum, and just used that, not caring the age of the bits. And THAT is why this issue is such a hot potato.
But this problem, this issue, is far from alone. There are dozens of such anachronisms and anomalies in the Voynich which are likewise so treated. Always in one direction, of course: 1420 and genuine. And any of the evidence found which does not contradict that verdict is never altered, never questioned.

The assumption is that the MS was created well within someone's life span, which is completely reasonable, as it is the case for essentially all books that aren't obviously log books. This was COMBINED with the result of the four samples which confirmed that.
But Rene! You just affirmed the one thing I've been pointing out! You are agreeing this was done! You even used the word "assumption" again! No, we cannot make such an "assumption" at all, and no data ought to be manipulated to fit this, or any such assumption.
(17-04-2024, 01:37 AM)ReneZ Wrote: You are not allowed to view links. Register or Login to view.This assumption was not even made beforehand. It was only made after the result showed that this is clearly what happened.
Well arguably that is even worse. The standards have been altered based on the results... and "no" the results do not show "this is what clearly happened", the results showed a span almost an entire lifetime, arguably more, and then were changed to FIT a lifetime. It is the exact reverse of what you wrote.
(17-04-2024, 01:37 AM)ReneZ Wrote: You are not allowed to view links. Register or Login to view.Now the combining of the four samples can be described in words, not using formulas.
For one folio, the probability that the date is after 1450 may be 1%.
If we just had that one folio, then that would be our uncertainty.
However, we have three more folios, each with a similarly low percentage that the date is after 1450.
This means that we have even greater confidence that the book as a whole is from before 1450.
Given that the 95% range is still about 30 years, which is on a scale of a single person's adult life span, the creation of the MS well within several decades holds.
With respect to the question whether the MS is proven to be genuine, I would add "beyond reasonable doubt". While the forensic evidence is clearly the strongest, there is a lot more than that.
There is far too much to parse in that, but it is irrelevant, moot to the points I made, which you both deny and admit in the same post: Simply, that the actual results are at least 50-60 years apart; but whose range was shortened (by whatever process, as in the one you relate, just above) to 1404-1438, based on
the assumption that the Voynich was created in a far shorter time than the test results of 50 to 60 years apart.
This is simple, and all that I have been saying... for years now, and is still not being denied by anything I've read here, nor anywhere else. What this means, how people chose to interpret this, is up to them... as it actually should be.
Rich.
