Text and context

I cannot stress this enough: having both C14 analysis and fashion available to us and overlap so nicely is a tremendous luxury. This is not conclusive, it is double conclusive. Why struggle?

One can argue about the best possible wording, but the key point is that the two consistent estimates for the origin of the MS are totally independent estimates.
This indeed makes the dating very strong.

There is even a second luxury. We have no insight in the analysis and experience of the Morgan curator who concluded on the 1420's date. This might make it easy to not consider it strong evidence. However, thanks to Koen's blog entry, everyone can see for themselves what it is based on.
So, while I consider the curator's statement the most important one, Koen's blog is extremely helpful.
