The 10-ins tall statuette of a man called Neb-Senu, which dates back to 1800 BC, mysteriously spins 180 degrees with nobody going near it, according to news reports.
Curators were baffled after they kept finding it facing the wrong way and rigged up a time-lapse camera to catch whoever was moving it.
But incredibly the camera shows the figure moving of its own accord in front of crowds of visitors who pass by with hardly a second look.
Now TV brainbox Brian Cox, who presents programmes such as the Wonders of Life, is among a group of experts being asked if they have any idea what is causing the phenomenon.
The statue has been in the Manchester Museum for over 80 years.
