A statue that was once part of an ancient Egyptian god's burial was put on display at the Manchester Museum in England 80 years ago when it was found in the 4,000 year old tomb.
Though the statue itself seems to blend in with the artifacts around it, what it does when no one is watching makes it entirely unique.
When the statue's current caretaker, Campbell Price, noticed that the statue was often moved askew to its normal position, he corrected it by turning it around.
He found that the next day, it was back to its askew position. That's when he decided to take a time-lapse video of the artifact over a week to prove it was moving on its own. In the video, the artifact can be seen slowly turning completely around.
"In Ancient Egypt they believed that if the mummy is destroyed then the statuette can act as an alternative vessel for the spirit," Price said.
While Price is convinced it has an other-worldly explanation, others have offered more mundane explanations for it. They believe it is caused by the vibration of the stone against its glass case, or the footfalls of museum visitors.
Price said the direction it turns in makes it difficult to determine the cause.
"Why would it go a round in a perfect circle? It would be great if someone could solve the mystery," he said.
