Some recent scientific analysis [March 2025] has been carried out on the famous Dagobert skull kept at Cercle saint Dagobert. Provisional summary as follows;
"The skull, carefully preserved in its reliquary and part of the treasure of the Collegiate Church of Saint Waltrude in Mons, is therefore not that of the unfortunate King Dagobert II.
Indeed:
bone age calculated based on craniofacial sutures allowed us to arrive at an average estimate of 35 to 45 years at the time of death, while history tells us that King Dagobert II was 27 to 28 years old when he was assassinated; radiocarbon dating places the skull in the 13th century, making it impossible to believe it belonged to the martyred king.
This mysterious skull did not belong to a Merovingian king but to an unknown person from the 13th century who was mortally wounded by a bladed weapon (such as a short-handled battle axe) applied vertically and fracturing the apex of the cranial vault. The cutting edge of the axe head must have been rounded and thus responsible for the arcuate appearance observed at the ends of the fracture, while causing a very deep and transfixing injury to the vault of the head in the centre (with some splintering irregularities due to the weight of the weapon and therefore its not only sharp but also blunt nature), undoubtedly damaging the meningeal layers as well as the underlying brain (e.g., hemorrhage, deep parenchymal contusion). Associated fractures of the facial bones were also found, most likely related to blows inflicted with a blunt instrument, although no further details are available.
King Dagobert II kept his sad end, his myth, and his legend to himself.
