William the Conqueror [SEP] Death and aftermath
The funeral, attended by the bishops and abbots of Normandy as well as his son Henry, was disturbed by the assertion of a citizen of Caen who alleged that his family had been illegally despoiled of the land on which the church was built. After hurried consultations, the allegation was shown to be true, and the man was compensated. A further indignity occurred when the corpse was lowered into the tomb. The corpse was too large for the space, and when attendants forced the body into the tomb it burst, spreading a disgusting odour throughout the church.
