Tutankhamun was buried in a veritable Russian doll assemblage of boxes. He was inside a coffin inside a coffin inside a coffin inside a sarcophagus inside a shrine inside a shrine inside a shrine under a canopy inside a shrine inside a room in his tomb!
The entire thing pretty much filled the room it was placed inside, with just enough space for the painters to squeeze round as they completed the decoration of that chamber. We know they did that last, as the wall through which the containers were brought was also decorated.
This is a detail from the third shrine (we count from the outside in but it’s not clear if the Egyptians would agree that this is the right order). All of the shrines are wood covered with gesso and then a thin layer of gold and all are decorated with texts and images like this.
The decoration here is of two guardians/demons rather than gods. As is usual for such entities they carry knives, presumably in this case to protect the king who rests within. You can also see Tutankhamun’s nesu bity name (Nebkheperure) scattered through the text in cartouches.
When I took this photo in 2016 the shrine was in the Egyptian Museum in Tahrir Square, Cairo. Now it is in the Grand Egyptian Museum. The old accession number was JE60667.
