I struggled with this one, too.  I originally had a more standard premise in which the slaves are discussing trivialities like sports and the weather, and one of them is pissed that they never discuss the possibility of revolt.  But after days of going back to it and then giving up and leaving it to simmer, it never jelled (gelled?  Checks dictionary…huh, either is correct..).  It was kind of a shame to lose a joke about being able to name all of the Pharaoh’s cats, but I thought a completely different approach was needed.

I came back to the thing about this art that drove me bugfuck, which was that whether that circle in the back is the Sun or a completely full Moon, the shadows should not be pointing sideways.
