...errr...actually, if you want to get very pendantic about decomp, mummified (deliberate act of drying a body out to preserve it)/dessicated (accidental act of drying a body) corpses can, and will, decay (further).

Basically, the idea that mummification/dessication is 'eternal' both work on the assumption that the body will be kept in the same situation as deposited.

Move the body from that situation (or remove the wrappings from a mummy), you will get rot/decomposition of the body.

I suggest you Google what happened to the two infants which they found in King Tut's tomb for a very famous example of 'mummies do actually rot'...or (for dessication) the ridiculous lengths that the researchers who examine any pre-historic/historical dessicate remains have to go to to prevent the further breakdown of the body.

(And honestly, the way it's described makes it sound like the individual was mummified in the early manner which was used by the Egyptians...Or in the manner which the Incans used)
