f17r

[Helmut Winkler]

[...] if you take the C14 dating into acount, it should be around 1420, the marginalia with the big  loops are late 15th c., let us say around 1480, the quire markings should be about the same time, the foliation is later, I think  17th c.

The problem is that the f17r marginalia has both the big loops and Voynichese at the end of the line (which I first saw on my trip to the Beinecke in 2006 using a black lamp).

This seems to imply that the two were written at around the same time.

You find the same problem in the last line of 116v, i.e. Voynichese and 'normal' script together, I would  say that the person that wrote ther marginalia at the end of the century could read (and write) Voynichese, whatever that implies.  It is one of the reasons that I think it means that the ms. is not a ciphre, but a plaintext and readable and understandable
