Bad news: f116v was substantially mangled by Retracer

There is a very strange glyph that look like an overlay of two different shapes. Both of them appear to be roughly the same color, so I'd say this mess could have been created in one sitting. I see no obvious signs of past writing, previous faint strokes, etc.

Register or Login to view.The worm-scraped patch 1, that runs along the valley crease of the parchment, is inside the red polygon (B).  It visibly damaged glyphs on lines 2-4.  It is not clear to me which parts of those glyphs are original, which are correctly restored, and which are wrongly restored.

The glyphs are visibly damaged, and to me it looks like even the darkest strokes were disrupted by this damage, which suggest to me that the worms happened after the writing was finished and there was no attempt to write over these glyphs after the damage was done.

Maybe the rationale for having both lights on was to separate dark spots created by pigmentation from dark spots created by shadows on the rough surface. Similar to the effect of a circular light source.
