Capital N in incantations

[MarcoP]

Hi Anton,
I feel quite sure it is N. for "Nomen": a placeholder where the name of the officiant, or the person object of the spell, must be inserted.

Your incantation:
"Precipio vobis febribus ... ut recedatis a famulo dei +N.N. et amplius non ledatis"
I order to you, fevers, ... to recede from the servant of God +N.N. and not to hurt him any more.
