Although the tomb was clearly disturbed in antiquity and its contents have been described as disordered and chaotic, Martha Bell argued that this disarray was more apparent than real. Her reconstruction of the layout of the tomb indicates an orderly and deliberate arrangement of artefacts, and she suggests that the impression of chaos might be due to the collapse of wooden objects caused by falling plaster and stone. The "cemented" chips and stains in the corridor indicate that water entered the tomb along the corridor ceiling, but the amount of water might not have been great, and most damage could have been caused by increased humidity rather than direct contact with water. Bell also suggested that the moisture under the mummy might have resulted from rainfall shortly after the tomb's opening in 1907. Other damage to wooden objects might result from an insect attack.
