The coffin was opened in order to apply modern scientific techniques
to a body known to be in remarkable condition. The other surprise for
the scientists was that the body was not embalmed; it was naturally
dried out with all its internal organs. The bishop was buried on a
mattress stuffed with herbs including juniper and wormwood, and a pillow
of hops, which the scientists believe would not just have masked the
smell but helped preserve the remains.
Although the colours have faded, his clothes were also perfectly preserved, including a velvet cape and leather gloves.
