Gregory of Tours (Gaul) wrote his ten books of Histories (known commonly in English as the History of the Franks) during his episcopal reign in Tours between 573 and 594. The books vary in scope and length. The first book covers 5,596 years from the creation of the world to AD 397, that is the death of Saint Martin of Tours, Gregory`s predecessor in bishopric. The second book deals with the history of Gaul between 397 and 511, the latter being the year of death of King Clovis I. The third and fourth books cover the next 64 years till the death of Austrasian King Sigibert II in 575. Finally, the following six books describe exclusively the sixteen years from 575 to 591. Probably in 594, Gregory added the list of bishops of Tours in the end of the Histories, with brief accounts of their actions.
