Morten St George Theory

It's an ordinal number. It's 11m9 .

The superscript is normal. It means 11th (like we add the "th" part in English). Like this 11th

The other quire numbers have it also. The 11 is no different from the other quire numbers.

The "9" at the end is the Latin abbreviation for "-us"  So you have primus, secondus, tertius, etc. Sometimes it is n9 or m9 at the end as in septi[mus].

Thanks, JP. I view getting it right as a much better objective than winning a debate.



From what I saw, the "n" of "11mn" (second image) had a left hook just like another letter "n" (third image) but unlike the shorthand "9" (first and last images). Thus, I was forced to conclude that the last character of the page 72 quire number was an "n" pretending to be a "9". My guess is that you never encountered anything like the Rosicrucians in your medieval studies. They did a lot of pretending.
