I hope everyone who attended the Voynich Conference 2022 hosted online by the University of Malta enjoyed the presentations and the Q&As.
In Lisa Fagin Davis’ final presentation, she mentioned her recent theory that p/f were in fact ke/te: and mentioned that she’d thought this up, but then found it on Cipher Mysteries. If you want to see the original page I put up in September 2020 suggesting this idea (along with her comment near the bottom), it’s right here, along with the August 2020 page where I started exploring the behaviour of single-leg gallows.
There’s an additional aspect to the set of gallows/e/ch groupings I discussed in 2020, which is that you can usefully compare the (parsed) ch:chch ratio in the text as a whole (which is 10616:18 (0.17%)) both to the (parsed) ratios of strikethrough gallows preceded by ch…
- ckh:chckh = 634:242 = 38.17%
- cth:chcth = 766:139 = 18.15%
- cph:chcph = 185:27 = 14.59%
- cfh:chcfh = 58:15 = 25.86%
…as well as to the (parsed) ratios of strikethrough gallows followed by ch:
- ckh:ckhch = 871:5 = 0.57%
- cth:cthch = 902:3 = 0.33%
- cph:cphch = 211:1 = 0.47%
- cfh:cfhch = 73:0 = 0%
This, too, is a strikingly asymmetric result; and would seem to suggest that the ch:chch ratio is practically identical to the ch:c<gallows>hch ratios, yet completely unlike the ch:chc<gallows>h ratio.
I would take this as reasonably good support for the idea that c<gallows>h is actually a visual proxy (and it doesn’t really matter whether this is for scribal, cryptographic, or steganographic reasons) for <gallows>ch, because Voynichese seems to want to avoid c<gallows>hch almost exactly as much as it wants to avoid chch.
Perhaps combining this result with the pe/fe result (and other “forbidden” Voynichese combinations) might be the start of something really positive…
