Budapest - The Buddha statue from China that conceals the remains of a monk who turned himself into a mummy almost a millennium ago is the centrepiece of an exhibition in Budapest.
Visitors to the popular Mummy World exhibition at the Natural History Museum see a golden statue of a sitting Buddha, about 1.2m tall.
On a television monitor, they can see the skeletal remains of the mummified monk inside it.
"The Buddha statue belongs to a Dutch private collector and when he bought it, he had no idea what it was hiding inside," said Ms Monika Kiss- Stefan, a spokesman for the Budapest museum.
The travelling exhibition from the Drents Museum in Assen, the Netherlands, is on display until mid-May, when it will go to Luxembourg.
The statue's secret was revealed gradually, starting in 1997. Its owner suspected it might contain something inside and took it to Utrecht University to have it carbon-dated. Samples were taken that found a body from the 11th century was concealed inside, Budapest museum curator Ildiko Pap said.
A pillow it was sitting on was dated to 300 years later.
Cat scans were done in 2013 and last year. The 2014 scans, at the Meander Medical Centre in Amsterdam, found that in the abdominal cavity, instead of organs, there were paper scraps printed with ancient Chinese characters.
The Budapest museum staff were unable to say what the characters mean.
Ms Kiss-Stefan said that while there were about 20 to 25 mummified monks around the world, the one on display was the only one known to be concealed inside a statue. She said the monk had prepared for his death meticulously.
Monks who choose self-mummification ate only seeds for a long time and then roots of a poisonous plant to prevent maggots from eating their flesh, she said. They spent their last days in a pit, meditating, and when they died, their bodies were left until they became mummified.
Museum curator Pap said self-mummification was practised in the 10th and 11th centuries, spreading from Japan to China and elsewhere in Asia.
It was not seen as suicide and only high-ranking Buddhist masters were allowed to practise it in order to reach Nirvana.
The mummified body was covered with clay about 200 to 300 years after the monk's death, followed by several layers of enamel and finally golden paint, to make the statue, she said.
