Chance finds of coins and pottery fragments and a fine head of
Minerva are reminders of the Roman settlement carrying the Celtic name
Aballo, a
mutatio or post where fresh horses could be obtained. Two pink marble columns in the church of St-Martin du Bourg have been reused from an unknown temple (
Princeton Encyclopedia). The Roman citadel, on a rocky spur overlooking the Cousin valley, has been
Christianized as
Montmarte ("Mount of the Martyrs"). In the Middle Ages Avallon (Aballo) was the seat of a viscounty dependent on the
duchy of Burgundy; on the death of
Charles the Bold in 1477, it passed under the royal authority. The castle, mentioned as early as the seventh century, has utterly disappeared.
King Arthur and the French Avallon theory A theory exists which proposes that the
Isle of Avalon mentioned in
Arthurian legend is, in fact, Avallon in Burgundy.
Geoffrey Ashe first mentioned the French Avallon theory in his 1985 book,
The Discovery of King Arthur. His theory is that "King Arthur" is based on the historical
Romano-British supreme king
Riothamus, who reigned between 454–470, and whose life and campaigns have parallels to the accounts of "King Arthur" in the first medieval accounts of King Arthur by
Geoffrey of Monmouth (, ). According to Ashe, in the year 470, Riothamus disappeared (and presumably died) in the neighborhood of Avallon after being defeated in the battle of
Déols by
Euric king of the
Visigoths, whom the
Western Roman Emperor Anthemius had hired Riothamus to fight against. This, and other aspects of his reign, made Ashe propose him as a candidate for the
historical King Arthur, with Avallon becoming the Arthurian
Avalon. No ancient source mentioning Riothamus places him anywhere near Avallon and Geoffrey of Monmouth, who is the first to mention "the isle of Avalon" (Latin
insula Auallonis) and based his description of the isle on
Classical descriptions of the
Fortunate Isles, is explicit that it was an island in the western seas. ==Population==
