In the musée des Antiquités in Rouen, one can see a child mummy (2-3 years of age) discovered in 1889 in Akhmim by G. Le Breton who was at that time the director of the museum. It has the classical external appearance of a mummy, but x-Rays examination shows that the head is joined to the body with a piece of palm stalck (gerid). Several mummies present such a characteristic which is very often interpreted in terms of poor quality mumification. But it appears that such a fracture cannot occur during the mumification process, but, on the contrary, can occur a long-time after death. The fracture was repaired using a stick to guarantee the body unity of the deceased, one of the most important concepts of the Egyptian Afterlife. This gerid is a testimony of a post-burial intervention different from what can be done in the Necropolis of Alexandria. It also means that the mummy bandaging is not the original one as the mummy needed to be wrapped an other time after the head was replaced onto the body.
