Historians continue to debate over the authenticity of a mummifed head found in the attic of a tax collector. Some believe it is the remains of "good King Henri" (Henry IV of France, murdered in 1610), while others believe the claim is "rubbish."
During the French Revolution, Henri IV was disinterred from his royal resting place and buried in a mass grave. At some point, his head was removed, leading to claims that the head found in the attic in 2008 is that of the monarch. The controversy is the subject of a new book by Stéphane Gabet and Philippe Charlier, Henri IV: The Mystery of a Headless King, who believe that the identity of the head can be verified.
