Tutankhamun's heart is missing

The ancient Egyptians considered that rebirth after death was conceivable, but that this could only be accomplished if the corpse was kept in a lifelike state. They created the science of artificial mummification as a result of this.

To keep a lifelike shape, the body was first desiccated in natron salt before being wrapped in numerous layers of bandages. At the beginning of the mummification procedure, the body's internal organs were removed and kept separately. The brain, whose purpose was then unknown, was simply discarded; the heart was thought to be the organ of reasoning. The heart would therefore be needed in the afterlife. As a result, it was left in place and, if accidentally removed, was swiftly sewed back, but sometimes not exactly where it had been.

But Tutankhamun is heartless, which is one of the most interesting facts about King Tut. He was instead given an amuletic scarab with a funeral spell engraved on it. This might have occurred due to carelessness on the part of the funeral directors, but it could also indicate that Tutankhamun passed away far from his house. His heart might not have been able to be maintained by the time his body got to the undertakers' workplace.
