What is "ruricius"

Ruricius I (c. 440c. 510) was a Gallo-Roman aristocrat and bishop of Limoges from c. 485 to 510. He is one of the writers whose letters survive from late Roman Gaul, depicting the influence of the Visigoths on the Roman lifestyle. He should not be confused with his son-in-law, Saint Rusticus (Archbishop of Lyon).
