|Missal leaf, with mistakes.|
In the case of the small missal or breviary leaf to the left (the whole leaf measures only about 5 3/4" by 3 1/4"), at least two errors can easily be seen.
The more obvious one involves the red (i.e., rubricated) text written into the lower margin. It is, as one might be able to see, preceded by a little red caret; the matching sign can be found in line 18 of the first column, just to the left of the two-line red "n" in the right hand column. As I hope is obvious, the position of the matching sign indicates where the added passage belongs.
Very possibly, this was a mistake by the primary scribe; at the least it seems to have been corrected by a second scribe, who uses a single-compartment a, rather than the main scribe's regular, two-compartment a. It is notable that this correction has been written on a couple of added ruling lines, provided just for this passage.
The second error, however, is clearly made by the rubricator.
Although they may be difficult to see on the full-page image of this page, guide letters survive in the right-hand margin of this page: q, n, and n. The first two were no trouble for the rubricator, but something went wrong with the third:

I find it strangely comforting to know that my own failures, at times, to follow directions are nothing new in the world, and even medieval scribes and rubricators had their off days.
