One of the oldest and most puzzling mysteries in human history is the sudden death of Egypt's boy king Tutankhamen. His tomb was exhumed by archaeologist Howard Cater back in 1922 and experiments done on 1968 showed swelling at the base of the king's skull.
This gives the impression that he received a massive blow to the head. More recent studies, however, have revealed that King Tut also suffered a badly broken leg. Egypt Supreme Council of Antiquities General Secretary Zahi Hawass commented, "He was not murdered as many people thought. He had an accident when he was hunting in the desert."
Further investigation has shown that the chariots in his grave are not merely ceremonial ones but were actually used by the king while he was still alive. Cairo Museum Nadia Lokma argued that "these chariots are hunting chariots, not war chariots. You can see from the wear on them that they were actually used in life."
Aside from that, a garland of flowers consisting of cornflowers and mayweed were also found in the grave. According to botanists, these flowers were in bloom during the months of March and April. Since the mummification takes around 70 days, it can be assumed that he died around December which is the middle of the winter hunting season. Source: Independent News U.K.
