Per Karsten, director of the historical museum in Lund, explains to Radio Sweden, that the bishop was initially exhumed because the cathedral had obtained permission to remove the bishop's coffin and bury him outside Lund.
Karsten and his team were allowed to open the coffin "to ensure that we could make all the necessary scientific analysis before he was destroyed in the ground."
Burying the mummy underground in a cemetery would have destroyed it within a couple of years, according to Karsten.
Laughing, Karsten says: "The cathedral repented when they found out our fantastic medical results of the investigations of the mummy, so now he's being returned to the cathedral today, so that's a very good result for the project."
"We will surely miss him," says Karsten, who will be talking a little bit about the scientific discoveries his team made about the bishop.
Karlsten said that the medical journal that scientists have put together based on studying the mummy have revealed that his illnesses were thoroughly modern, including stress and gout.
