Catalan Zodiac Rose S.XV

[quimqu]

Also, there are 13 months here, with some kind of Jaber-something between January and February, or maybe one name overwritten over the other. Maybe a mistake? Could someone read these month names?

I think this is due to the lunar cycles. Sometime we have twice full moon in the same month.

And yes, I read the month's names (I already posted them in the Koen's month name colletion thread You are not allowed to view links. Register or Login to view.). Months are:

janer
fabrer
marts
abril
maig
juy' (there is a dot over the y, nowadays it is juny, "ny" is pronounced as the spanish ñ)
juliol
agost (twice)
satembr (the horizontal line may indicate the the final e is missing, so it should be satembre)
octubre
noembr (again the horizontal line, this should be noembre)
desembr (again, the horizontal line may indicate the e is missing, desembre)

There are 19 tables in the manuscript. I attach here the links. The circles appear also in some hour and day values.
