Gildas and Badon Arthur is not mentioned in
Gildas' 6th-century book
De Excidio et Conquestu Britanniae. Gildas does mention a British victory against the
Saxons at the "Badonic mount" (
mons Badonicus), which occurred in the year of Gildas' birth and ushered in a generation of peace between the two warring peoples. This engagement is now referred to as the
Battle of Badon. Gildas describes the battle as taking place "in our times" and being one of the "latest, if not the greatest" slaughter of the Saxons, and that a new generation born after Badon had come of age in Britain. Later Cambro-Latin sources give the Old Welsh form of the battle's location as Badon, such as in the
Annales Cambriae, and this has been adopted by most modern scholars. Gildas' Latin is somewhat opaque; he does not name Arthur or any other leader of the battle. He does discuss
Ambrosius Aurelianus as a great scourge of the Saxons immediately prior, The
Historia says: "Then in those days Arthur fought with the kings of the Britons against them [the
Saxons] but he himself was the commander of battles
(dux bellorum)". Twelve battles fought by Arthur are listed. Commenting on Arthur's post-
Conquest portrayal as a king, the historian Nicholas Higham observes "Earlier texts are uniform in depicting Arthur solely as a warrior or a leader of warriors, whether ‘real’ or supernatural .... In the context of the central Middle Ages, it was a king's role to head the army, leading the forces of subaltern rulers. ‘Overkingship’ was well known, in Wales as elsewhere. It was a small step therefore from ‘commander of battles’ to a quasi-imperial figure commanding the Welsh kings as well as their forces. This was to prove a landmark shift within the Arthurian tradition, leading directly to 'King' Arthur."
Annales Cambriae The earliest version of the
Annales Cambriae (
Welsh Annals) was composed in the mid-10th century. It gives the date of Badon as 516 and lists Arthur's death as occurring in 537 at the
Battle of Camlann. Like the
Annals, all other sources that name Arthur were written at least 400 years after the events which they describe. The work considered Arthur as historical and featured
Ambrosius Aurelianus as his apparent employer. Malmesbury also mentioned the finding of a tomb of a certain "Walwin" (a supposed nephew of Arthur) in the time of
William the Conqueror.
Historia Regum Britanniae Arthur was first styled as a
king of the Britons in
Geoffrey of Monmouth's pseudo-historical chronicle
Historia Regum Britanniae (
History of the Kings of Britain), which dates to c. 1136. Geoffrey also refers to Ambrosius Aurelianus (whom he calls Aurelius Ambrosius) as a king of Britain and an older brother of
Uther Pendragon, father of Arthur, thus establishing a familial relationship between Aurelianus and Arthur. He identifies Aurelius Ambrosius as the son of Constantinus, a Breton ruler and brother of
Aldroenus.
Hagiographies Arthur is mentioned in several 12th- to 13th-century
hagiographies of Welsh and Breton saints, including those of
Cadoc,
Carannog,
Gildas,
Goeznovius,
Illtud, and
Paternus. The
Legenda Sancti Goeznovii is a hagiography of the Breton saint Goeznovius which was formerly dated to c. 1019 but is now dated to the late 12th to early 13th century. It includes a brief segment dealing with Arthur and a leader known as
Vortigern.
Bardic sources There are a number of mentions of a legendary hero called Arthur in early
Welsh and Breton poetry. These sources are preserved in High Medieval manuscripts and cannot be dated with accuracy. They are mostly placed in the 9th to 10th century, although some authors have dated them to as early as the 7th century. The earliest of these would appear to be the Old Welsh poem
Y Gododdin, preserved in a 13th-century manuscript. It refers to a warrior who "glutted black ravens [i.e., killed many men] on the rampart of the stronghold, although he was no Arthur." The Welsh poem
Geraint, son of Erbin describes a battle at a port-settlement and mentions Arthur in passing. The work is a praise-poem and elegy for King
Geraint, usually presumed to be a historical king of
Dumnonia, and is significant in showing that he was associated with Arthur at a relatively early date. compiled around 1250, though the poem itself may date to the 10th or 11th century.
Y Gododdin was similarly copied around the same time. The two poems differ in the relative archaic quality of their language, that of
Y Gododdin being the older in form. However, this could merely reflect differences in the date of the last revision of the language within the two poems, as the language would have had to have been revised for the poems to remain comprehensible. ==Alternative candidates for the historical King Arthur==
