Aubert of Avranches was an 8th-century bishop and presbyter born into a noble family in Genetas. During the reign of Childebert III, he was selected to lead the See of Avranches due to his reputation for piety and wisdom. He is most famously remembered for his role in the founding of the Mont Saint-Michel monastery, following a series of divine encounters with the Archangel Michael.
Life and legend
According to tradition, the Archangel Michael appeared to Aubert three times to command the construction of an oratory on a tidal island. After Aubert initially doubted these visions, the angel reportedly struck him in the head, leaving a physical hole in his skull. This led to the establishment of the site, which later housed Benedictine monks. He died around 720 or 725 in Avranches.
Veneration
The Catholic Church recognizes Aubert as a saint, celebrating his feast day on 10 September. His skull, which contains the legendary indentation from the angel's touch, is preserved at the Saint-Gervais Basilica in Avranches. While some suggest the mark may be the result of ancient medical trepanation, the relic remains a significant object of interest.
