Which things in the manuscript can be dated?

[Koen G]

A palaeographer can tell at a glance the approximate dates of each of these, but I now have data to back it up. A lot of it. This is important because an expert has already said that John Dee did the foliation. I wanted to find evidence to support or refute that claim (I don't care what the answer is, I only care about finding the answer).

Exactly. The tricky part is to find those specific things which are clearly present in the VM and can be found only in other works within a certain date range.

For the bag sleeves, the impulse to look deeper into it came from the fact that the date for the oldest of the Devonshire Hunting Tapestries had been adjusted to 1430, because after that bag sleeves would have been out of fashion.

It would be most interesting if other details can be dated this way.
