f114r - what happened?

[Gregor]

I've noticed something possibly interesting on the page f114r.

There is some text of few words which looks like inserted between lines:

It feels weird to me. If it is a continuation of the previous line then it should start at the left edge but instead it is aligned to the right edge.

It may feel like it was inserted later but I wouldn't say so. Notice that the scribe does a weird thing and goes up with the previous line to make a place for it. I made a sketch of it for you.

So how do you think, what happened here? Was the scribe copying text from another source and realized that he lacks place? But why he lacked space? He was writing from top to bottom afterall so he should have space in the bottom.

Scribes were only human, after all. The uneven lines of text might indicate that the writer had to take a break, for example, to use the toilet. Under pressure or due to sudden urgency, their hand could stray from the line. Upon returning, they would notice the mistake and carefully fill in the missing parts. Another explanation could be fatigue – long hours of tedious calligraphy might cause the hand to slip off the line. After a short rest or the next day, the scribe would return to the text and correct any inaccuracies.
