Aquilinus of Évreux

Aquilinus of Évreux, known in French as Saint Aquilin, was a Merovingian-era bishop of Évreux in Neustria whose memory is preserved chiefly in later medieval hagiography rather than in contemporary charters or chronicles. Tradition places his birth at Bayeux, in present-day Normandy, in the early seventh century, commonly given as about 620, and describes him as the son of a noble Frankish family. In keeping with the expectations of his rank, he took up arms and served in the military household of Clovis II, king of the Franks in Neustria and Burgundy in the middle of the seventh century. After a number of years of campaigning he left the army.

He then married a woman of similar aristocratic standing. The couple is said to have lived a devout married life. After a period of years they agreed to separate in order to pursue a more exclusively religious vocation: Aquilinus received ordination to the priesthood, and his wife is reported to have taken the veil. In time the clergy and people of Évreux chose him as their bishop. Traditional lists place his episcopate in the later seventh century, often from about 670.

As bishop of Évreux he acquired a reputation for pastoral care, personal austerity, and holiness of life, though specific acts of his administration are not recorded in surviving seventh-century documents. Toward the end of his life he withdrew from the public duties of the see to live as a hermit, a pattern not uncommon among Merovingian bishops who sought a contemplative close to their careers. He died, according to the received chronology, in 695. His feast day is observed on 19 October.

Veneration of Aquilinus remained essentially local, associated with the church of Évreux. He belongs to the large class of early medieval saints whose cult arose from diocesan memory and liturgical commemoration rather than from a formal process of canonization by a pope. No reliable contemporary source records the name of his wife, whether the couple had children, the precise site of his hermitage, or the exact place of his burial. He was neither pope nor patriarch, and he is not known to have belonged to a named monastic order, though his last years were spent in eremitical retirement.
