Sigebert IV (c. 671 - c. 679) was the son of Dagobert II and a Saxon duchess called Mathildis (also called Mechthilde),[1] and the grandson of Sigebert III of the Merovingian dynasty.[2][3] He is believed to have died either just before or after his father and other members of the royal family, who were killed on the orders of Ebroin, the Frankish Mayor of the Palace of Neustria.[4]
In the 10th-century biography of Saint Arbogast, Vita Sancti Argobasti,[5] Sigebert is mentioned but not named as having died during a hunting accident and later miraculously raised from the dead by Arbogast, Bishop of Strasbourg and close friend of Dagobert II.[6]
