On night, during roughly the 1930s, a museum guard at the Field Museum heard a blood curdling scream coming from the Egyptian wing. He found no one there, but one of the mummies had fallen from its base and was lying face down inside of its case.
When the story is repeated today, it’s usually said that the mummy was that of Harwa, The Doorkeeper of the Temple of Amun which has been in the museum’s collection since 1904. However, the earliest known mention of the incident (a Bulletin from the Field Museum reprinting an older piece by Henry Field from 1953) says it was naked, and Harwa is still covered, like a DECENT mummy.
Field, an anthropologist and grand-nephew of Marshall Field, wrote that he studied it carefully, but could find no possible explanation for why the thing fell over, and no way a person could have knocked it down – the locked case was filled with poison fumes to keep bugs out.
"The base extended at least four inches on each side of the dried skin and bones. No living person could have entered the poisoned case. No vibration in the building could have knocked it off the base without rending the walls, for the museum floats on an island of concrete, there being no hardpan on the filled-in land along the lake front.
"There is still no explanation of the scream or of the fallen mummy. It is just one more example of things we cannot explain."
