Capital N in incantations

[Helmut Winkler]

Thanks, Marco! You are right that our only hope is probably to find a similar sentence elsewhere. Still I must say that through threads like these, I have gained more confidence that these marginalia correspond to some medieval practice. We can strongly suspect that the first line is some invocation or instruction where a person's name was to be inserted. That's more firm footing than we had before, as far as I'm concerned. 

I also think that for the first line, we might still learn more by focusing on grammar and syntax. For example, if "dabas" is the Latin tense it appears to be, then it's a second person but not an imperative. But I don't quite see how to fit the perfect tense into this. Unless it's some kind of future tense. Or no verb at all..

If this of some help: dabas is second person imperfect of do, dedi, datum dare, to give  imperfect dabam, dabas, dabat, dabamus, dabatis, dabant,
