After analyzing the high-resolution image, I have come to the following translation with some doubts:
"mensis Aprili Aprili Lunam haec"
= In the month of April, this will be
and then it becomes illegible to me. I could guess an “erit” and then an l or even a d follows. Maybe: discrimen?
= in the month of April, the decision will be?
Reason:
m:
the m stands before a month name for mensis (month)
April:
if the left "April" is supposed to be April, it has one letter too many or he has mixed up the letters. And then it looks as if the word is repeated without the letter and written more hastily. Another repetition error?
the first "l" belongs to the a (see below)
the apostrophe at the end, which appears in both words, indicates the “i.”
Lunam:
is a common abbreviation (see below). I see the c before the 3, and that makes this interpretation a little uncertain, but I wouldn't overestimate the c.
The macron indicates the missing n.
haec:
The h is clear, the e has a small downward stroke like ae, and then hae fits. The c is then more of a guess.
What do u think?
