I'm puzzled by the number in the entry for the sheep. Normally we might see a superscript o in that location, indicating the last letter of vicesimo.Could this apparent t possibly be from vingt?
Isn't it just xxt for viginti, meaning 'twenty', with the penultimate t superscript?
I’m going with xxt = viginti as it makes the most sense. I have never seen that kind of “thinking in Latin” before on an inventory.
