That's mentioned but dismissed. I would think age might be a factor though. Some scribe took a break for whatever reason returning to the task after 10 years or so? > Although one cannot rule out completely that the clear separation between the two halves of the manuscript and the difference in writing patterns are due to a change of writing implement (a different pen), writing fatigue or some injury that the writer suffered when moving on to the second half of the manuscript, the more straightforward explanation is that a change in scribes occurred.
