Which things in the manuscript can be dated?

[Helmut Winkler]

From the C14 dating we know the ms. was written most likely around 1420.  the main part of the 'Voynich' script was written around 1415/25, which fits the palaeography, and the last of the marginalia, the script with the loops should be around 1450. Everyting else should be inside his time span. I think you could build a relative timeline inside the ms. from the development of script and illustrations, but have never taken much time and trouble about it, because I don't think it is going to help much with reading and understanding the ms.
