What did the nymph on the mid-left edge of f80v originally have in her hand?

[-JKP-]

The last shape looks like letter ю  

Or the other direction of the symbol that was used to represent "N" in this coded final line from a 9th century English manuscript.  The line translates to DEO GRATIAS (thanks be to God, using the "move vowels to closest consonant" code for the first two words) and some sort of weird Greek letter/other alphabet substitution for the AMEN.

It was discussed in this blog by Thijs Porck (with no identification of source of glyph).  Maybe someone on the board knows more about the source of the alphabet?

The vowel-substitution cipher (deo gratias) was popular in the Middle Ages. It doesn't stop anyone from reading it, but it does slow them down if they are glancing over someone's shoulder. Plus, they may have considered the words to have more force or "power" if lightly encoded (gnostic attitude).

The Greek letters (AMEN) are not weird for the time. That is how uppercase Greek letters were written in the early medieval period. In fact, some of these shapes became the basis for paragraph-reference markers in medieval Latin texts. This was a practical choice, since they would not be mistaken for Latin characters when they were written within the text as reference markers.
