Hintere Pfeilerhalle = Rear pillar hall
I think this is Thutmosis III running his Heb-Sed race, or is he going around purifying the temple?
(note vases and 'water-from-vase' hieroglyph)
I will study the hieroglyphs later...

I noted in the Erman book from which Wilkinson and Naydler got the image of Set teaching Thutmosis III that Erman gave credit to a Lepsius. I tracked Karl Richard Lepsius and his book Denkmäler aus Aegypten und Aethiopien,where I found the original drawing of that (plus several other Set sightings)! Photographer Arja Kontkanen says "We found SETH in one of the rooms near Festival hall" She has a larger view, showing there is still paint on the pharoah Sadly, some damage has occured since Lepsius' day.
