Storehouses of parchment

[ReneZ]

There's more than one way to interpret the data, and current evidence is insufficient to confer validity on a particular method.
What do you say to 1434-1445+ as a date for the last sheet of parchment?

To discuss this in a meaningful way, one would need to understand the process of determining a radio-carbon date.

One thing can be stated:
the probability that the parchment of the Voynich MS is after 1438 is 2.5%

This is not negligible, but it is small.
That it is after 1450 cannot be computed but it is very significantly smaller.

Fortunately, we have completely independent evidence that points to the 1420's, namely the clothing of some of the people in the zodiac pages.
