Gregory of Tours
Gregory of Tours was a Gallo-Roman historian and Bishop of Tours, which made him a leading prelate of the area that had been previously referred to as Gaul by the Romans. He was born Georgius Florentius and later added the name Gregorius in honour of his maternal great-grandfather. He is the primary contemporary source for Merovingian history. His most notable work was his Decem Libri Historiarum, better known as the Historia Francorum, a title that later chroniclers gave to it, but he is also known for his accounts of the miracles of saints, especially four books of the miracles of Martin of Tours. St. Martin's tomb was a major pilgrimage destination in the 6th century, and St. Gregory's writings had the practical effect of promoting this highly organized devotion.
