This is no ordinary Buddha statue. As the CT scan at the right clearly shows, there's a mummy concealed inside!
This fascinating artifact is currently on display as part of a mummy-themed exhibit at the Netherlands' Drents Museum (link also offers a glimpse of a particularly rad cat mummy). It's the first time the "Buddha mummy" has been shown outside of China; according to the museum, the statue contains the remains of a monk who lived "around the year 1100" and are possibly an example of self-mummification.
