Yeah, it is a serekh presented horizontally in the image I provided, perhaps because Tut's Horus name is so long.
OK pharaohs appear to have much shorter names and so their serekhs are often inscribed vertically.
I read your post about the oils but don't know if oils were poured directly onto the offering table or not.
I wondered if the oils used were simply fragrant or if they were used as a fuel source with a simple wick? Any idea?
