This is the one that looks like it has numbers on the bottom right. I mentioned this on the forum a couple of years ago but I don't think there were any responses.
It looks like 04 9° 9 (the glyph that looks like EVA-l is the old style of 4).
There's more than one way to interpret this, but one way would be day 4 of 9th month [140]9 (or month 4 9th day ___9). I suppose it could even be read in the other direction (day 9, 9th month --04).*
I tried to figure out if there were any lunar eclipses around this time but I can't remember what I did with the results of the search. It was years ago but I remember there being solar eclipses in April and October but I think I had to search quite hard to find specific info on lunar eclipses, March and September, but not September 9th (I have waaay too much data). It doesn't have to be an eclipse (or a date), but I felt that was a good place to start. There's probably more eclipse data online now than there was then, so it might be worth trying again.
But the problem with eclipses is they are only visible from certain locations, so it's not a trivial thing to try to geolocate them (plus the time of day factors in to whether one can see it). Eclipses are frequently mentioned in medieval manuscripts and sometimes there are calendrical charts working out when they will happen.
It also occurred to me that maybe it's just a date (like the date the manuscript was done), but the way it's tucked in with the drawing, it seems more likely it's related to the drawing in some way.
And... now I remember why I never finished this line of research... because it's endless. It's possible the first two characters are the common VMS "ox" combination and that only the last two glyphs are numbers (e.g., 9° 9) which could mean many things.
* Interpreting the ° symbol depends on context. In manuscripts, one often sees g° (grado) or m° (modo) as abbreviations but when it's next to a number, it frequently means it's an ordinal (e.g., 9° = 9th).
