Month names collection / metastudy

[MarcoP]

This image compares a few characters and bigrams from:

• One of the kalendars posted by R.Sale (You are not allowed to view links. Register or Login to view., 15th Century). I did a quick search and couldn't find 'rs', so I included 'ris' instead. I couldn't find no 'y' either (the ms is written in Latin).
  
• A You are not allowed to view links. Register or Login to view., Switzerland, from monasterium.net, a site that nablator pointed out maybe one year ago
  
• The Voynich manuscript
  

The other two sources don’t have that bastarda pointed ‘e’, which certainly is an interesting feature. Another other detail that doesn’t seem to be paralleled is the final -s in Mars (the Basel manuscript usually has nice 8-shapes as final -s). Voynich month ‘g’s are also peculiar, but the difference could be due to the hasty nature of the annotations and maybe the limited space. There are several other differences (e.g. 'r', 'y') and it's not always clear if they are relevant or accidental. Anyway, a more extensive search sounds interesting: I am quite sure that better matches can be found.

   

EDIT: Maybe this has been noted already, but I guess the dot above ‘y’ has the function of making it distinguishable from the common Latin prefix -ii which was usually written ij and can therefore be easily confused with y, if ‘i’ and ‘j’ have no tittles.
