The mummified remains of Peder Winstrup, the influential Bishop of Lund who died in 1679, have been shown to the public before he is due to be reburied at Lund Cathedral on Friday.
It is thought the cold dry air of his crypt caused his body to become mummified.
Scientists have spent the past 15 months studying his remains and scans of his body revealed he may have been bed ridden for a long time before his death.
They also revealed a mysterious human foetus had been buried with him beneath his feet.
His body, which was found to be clothed in fine velvet and leather glove is due to be reburied at Lund Cathedral on Friday.
