Month names collection / metastudy

[davidma]

Note that a e i o u all commonly take the circumflex whereas y is extremely rare.

We need examples of ŷ in manuscripts to be more confident of the possible date range.

I doubt it is so late in the 16th century: the unusual "e" was probably obsolete by then.

I agree, I think Gallica is our best friend here, there is a ton of manuscrits on it we could have a look through. I also feel that the e shape points to the names being written closer to the 1533 date rather than later.
