Eustadius of Mesmont

Eustadius of Mesmont was born at the end of the 5th century at Mesmont in Burgundy and died at Dijon in the 6th century. He was a monk, a Benedictine according to the German and French sources, and the first abbot of the abbey of Saint-⁠Bénigne at Dijon, about 525-535. He came from a rich family of the Gallo-⁠Roman nobility of Arvernian origin, which counted senators and governors of Autun among its members.

He was a great-⁠grandson of Bishop Gregory of Langres, who founded the abbey, and a maternal great-⁠uncle of the historian Gregory of Tours. He led the abbey until his death, died there and was buried near the crypt with the sarcophagus of Saint Benignus. He is commemorated on 3 January in the Catholic Church, in the Western calendar (new style).
