Maurontius of Douai was a 7th-century Benedictine abbot and nobleman born in Ponthieu. After spending his youth at the court of King Clovis II, he inherited significant estates following his father's death in 652. Influenced by a sermon regarding worldly vanities, he abandoned a planned marriage to pursue a religious life. He eventually founded the monastery at Breüil on his Merville estate, where he served as the first abbot, and later managed the community at Marchiennes.
Life and career
Following his conversion to monasticism, Maurontius served as a deacon and prior at Hamage. He demonstrated great respect for the abbot Amandus, even resigning his own leadership to serve under him during the latter's exile. After Amandus passed away in 690, Maurontius resumed his duties. He oversaw the monks at Marchiennes, a community that included a separate house of nuns led by his sister, Clotsinda.
Veneration and relics
After the community at Breüil was moved to Douai, his remains were transferred to the church of Saint Amatus. He is honored in Douai, where his statue stands alongside his parents. His relics are distributed across several locations, including the cathedral of Arras and the abbey of Saint Guislin, which holds his skull in a silver gilt shrine.
