And I would like to add this as well, because it was presented as complete nonsense:

Here in the picture, you can also see  that there could be two lines on the left side of the possible ‘T’ (the T remains speculative), so the lower loop may NOT belong to this T, it could be two lines!

The (admittedly very speculative) idea that this is a large A, again with a loop next to a Gothic T, as a ligature for Autem, is not out of the question.
