The king took an interest in Agericus' education, recognizing his intellectual promise in both humanistic and religious studies.
[2] Agericus played a significant role at the court of King Sigebert I of Austrasia (561–575) and his son and successor, Childebert II (570–596).
His remains were later transferred to Verdun Cathedral, where, until the last century, several of his personal belongings were preserved, including a wooden spoon with an ivory-inlaid handle and two ivory-handled knives.
