Physical evidence
Egyptologist Bob Brier has noted that despite its widespread depiction in royal portraits, no ancient Egyptian crown ever has been discovered. Tutankhamun's tomb, discovered largely intact, did contain such regalia as his crook and flail, but no crown was found however among the funerary equipment. Diadems have been discovered.[12]
It is presumed that crowns would have been believed to have magical properties. Brier's speculation is that crowns were religious or state items, so it is likely that a dead pharaoh could not retain a crown as a personal possession. The crowns may have been passed along to the successor.
