There does seem to be something which sometimes seems to cause an entombed body not to decay, but I don't know that there is any agreement on what causes this (beyond the standard conditions for mummification: extreme dryness, cold and/or complete lack of oxygen). My ignorance doesn't mean, however, that the conditions are not well understood by experts. In any case it might just be more or less of a coincidence that his was one of the bodies that this happened too (helped on by his instructions to examine his interred body allowing people to discover this).
Another conventional explanation is that when he knew he was going to die he took massive amounts of a poison that acts as a preservative. There might, of course, be a secret tradition providing the recipe.
And of course, something may be going on that is just plain beyond our present understanding. That I can propose slightly plausible vauge explanations doesn't mean that they are true. |
