Well, this is the first room of the Tomb of Tutankhamun that I have finished (Maya 2014). I had to build about 100 unique pieces. To build this correctly I used the original Harry Burton photos that were taken in the tomb as well as Howard Carter's original notes. Additional notes by Alfred Lucas and journals by Arthur Mace have also been invaluable. All of the cutaway illustrations of the tomb that can be found on the Internet are very inaccurate and I have decided to rectify the situation by building my own version of the tomb.
What amazes me is that all of the tomb illustrations I see on the Internet get a lot of the positioning wrong and miss the illustration of certain prominent pieces. The funny thing is that the same errors continue from illustration to illustration. It's a typical example of an illustrator making an error and then other illustrators basing their work solely on the previous illustrators. In the process the same errors get passed from illustrator to illustrator. Even prominent shrines and chests that should be seen in the Treasury are missing from illustration to illustration. It's nice just going back to the original sources (the photos, notes, and journals) so that the proper numbers of the black shrines, boats, kiosks, and other things indicated in the notes can be found, placed, sized, and oriented right. Missing items never seen (or seldom seen) in illustrations include a large shrine near the Treasury door, a harvest scene diorama which had a boat with sails and rigging sitting on top, and another boat (no. 314) that had dropped between the side wall (far right wall) and black chests nos. 292 and 296 (far right chests in rows 2 and 3 from the back).
I don't want to appear that I am bragging by finding lots of errors in other illustrations since I'll likely create a few myself. In my case though they will be fewer and different. I'm merely amused that they are all copying over the same errors and omissions. In one case I believe I can tell why a couple major omissions in Treasury pieces were made.
Another interesting observation: One simplification they also all have in common is that they only illustrate 6-8 boats along the north wall where all those black shrines are. In reality there were 15 boats of which almost all would be visible from the angle in which they depict the tomb.
