Saint Gregory of Tours names St. Martial, who founded the Church of Limoges, as one of the seven bishops sent from Rome to Gaul in the middle of the 3rd century. An anonymous life of St. Martial ("Vita primitiva"), discovered and published by Abbé Arbellot, represents him as sent to Gaul by St. Peter. Controversy has arisen over the date of this biography. The discovery in the library at Karlsruhe of a manuscript copy written at Reichenau by Regimbertus, a monk who died in 846, places the original before that date. The biography is written in rhythmical prose; Charles-Félix Bellet thinks it belongs to the 7th century, while Charles De Smedt and Louis Duchesne maintain that the "Vita primitiva" is much later than Gregory of Tours (died 590). Charles Ferdinand de Lasteyrie du Saillant gives 800 as the date of its origin.
