It’s the same with William the Conqueror. At least that was fate, not a creative choice. His bowels exploded while some monks in Caen were trying to cram his bloated corpse into a sarcophagus that was far too snug for him. The consequent stench rather ruined the solemnity of the remaining funeral rites. So that was the very last anyone saw of him. The bit before that wasn’t much more dignified. The bloating which necessitated the sarcophagus-cramming had partly happened pre- and partly post-mortem.
