Very nicely done indeed. If you have the names of the stars did you try to match the stars using the Latin names and the Voynich language? Otherwise in Greek.
Another apporach: if you can find a match by replacing a Voynich character by 1 letter and doing the same for all other stars somewhere you get words for the other stars as well. If that gives 1 or more matches that means you are on track !
22 Dec 1414, 17 Dec 1428, 7 Dec 1429, 15 Dec 1431, 7 Dec 1448, 15 Dec 1450, 7 Dec 1465, 7 Dec 1467, 7 Dec 1486 (this is the one I think is referred to).
okay nice progress Robert. (I examined many languages but did not find a consistent match)
And on those days, is this configuration visible from the U.K., whole Europe, Italy etc. or could you narrow it down to a specific region in the world where is can, or definitly can not be seen?
If you specifiy the 9 dates i assume these are for a specific time zone / location on the planet. I assume London cause it says on the picture. (somebody in the UK can not see the same star configuration as someone in the USA or China). My question specificly: would somebody in Italy see the same stars as drawn by you, in other words: is the difference very little/ not really visible, or should somebody in the UK see another sky?
something else: I did not find any serious attempt on Halley’s comet and the Voynich.
Would it be a lot of work, to investigate whether Halley’s comet is displayed in the manuscript. Preferable from the region of Europe. Halley’s comet appearances: …10 November 1378. 9 June 1456. 26 August 1531. Could you match any of these locations & dates ?

I followed Glen Claston, who claimed the language is English, and have kept that assumption throughout my research.
I think I found a way to relate the letters to astronomy. I made a picture that I would be happy to send to you.
Thanks
I don’t understand what you mean by ‘relate the letters to astronomy’.
And yes, I’d be happy to look at your picture.
If that configuration only occurs 9 times a century, what years did it occur in the 1400’s?
22 Dec 1414, 17 Dec 1428, 7 Dec 1429, 15 Dec 1431, 7 Dec 1448, 15 Dec 1450, 7 Dec 1465, 7 Dec 1467, 7 Dec 1486 (this is the one I think is referred to).

I did work on that, but the best I could find was that if it was visible in Europe, it wasn’t in America.

Yes, the dates were found for London, but I no longer think that city is involved.
There would be a slight difference in the position of the moon and viewing angle of the stars, but I don’t really know if it would make a difference.

I used Kronk’s online comet data and added it to Starry Night 4. The apparition of Halley’s Comet in 1531 is nowhere near the place of the 1533 comet.
Also, the Theatrum Cometicum (1666) shows a lot of comet paths.
“Kronk’s online comet data” ? I can not find that !
could you provide the URL for me please, or send it my personal email address please ?
(The “Theatrum Cometicum” has very beautifull illustrations, but Latin does not read as easily as it should be…;-) )
The URL is: http://cometography.com/
Don’t need to read Latin– just the dates.
