Nectarius of Auvergne was a 4th-century Christian missionary and martyr. According to various traditions, he traveled to Rome following accusations of conspiracy after his parents' death, where he was baptized by Saint Peter. He was later sent to Gaul to spread the faith, either by Peter or by Pope Fabian alongside six other missionaries. He is associated with the evangelization of the Limagne plain, where he converted a temple dedicated to Apollo into a Christian site.
