Liberated from the evil empire, but I couldn't find a great summary page including this exact piece. Frustrating!

Anybody have a good reference page for this one?

I know it's not truly possible to tell but looks to be depicting a black African woman.

For sure.

TBH I have no formal training in Egyptian history, but AFAIK across thousands of years, they were ruled by various kinds of ethnicities and peoples who looked somewhat different from each other.

I don't want to over-speak (because I'm just a layman), but I get the impression that the various kings & queens could range from identifiably African, to... Semitic / Arabic, to... their final conquerors, the Macedonians. (Greeks)

amazing that hair styles have changed so little in 3500 years…

Cold tomb

Hey I saw this tomb ! Very impressive and complete different from the ones around. It was the tomb of someone serving under Akhenaten hence the style. The tomb is actually unfinished and unpainted as the owner reverted to the traditional gods after the death of Akhenaten and built another tomb elsewhere.

Not sure what type of references you're looking for, but there are some descriptions on the Wikipedia page of the tomb TT55. Based on the description, I would guess this is one of the reliefs showing him and his wife on the eastern side of the main hall. One of the sources says it depicts a banquet and that his wife was called Merit-Ptah (see also here; this page is about a different person but also mentions TT55). There are more images on Wikimedia Commons with some more in the "reliefs" subpage. This one looks like the one in your post.

Excellent; thank you so much!

the tomb of someone serving under Akhenaten

Aha, the heretic one-god Pharaoh! I missed you saying that at first.

I kind of admire his massive balls for trying to convert the kingdom to a different theism, but OTOH the 'one-god' thing has played out pretty disastrously in later times IMO, so... yeah.

Ah, who the heck knows...?
