No jewelry or clothing were found near the body. The mummy is very well preserved. The fingers are in good condition, so much so that they can get fingerprints. Beard, hair and skin are excellently preserved, but the colors have been altered by time and prolonged immersion in the swamp.

The bones are almost dissolved due to the acidity of the environment that has soluble the mineral component of the bones. . The skin has taken on a very dark color, almost black, which like a parchment seems to cover the bones. The body had been preserved for a process similar to tanning, caused by the umic acid and the iron contents of the peat water that had made the skin very resistant and prevented rotting.
