Historical and traditional content
Although the show was initially perceived as pure comedy, in many ways it follows the medieval Arthurian legends, including such traditional characters as Lancelot, Guenièvre, Bohort (Bors), Perceval, Merlin, and the Lady of the Lake, as well as the Holy Grail and the sword Excalibur. The early seasons often include twists on traditional Arthurian or medieval themes, which might delight scholars; historians Eric Le Nabour and Martin Aurell have published two books based on the series, and a number of distinguished medievalists are interviewed in the 5-part documentary "Aux sources de Kaamelott" by Christophe Chabert, which accompanies the DVD sets.
Like other 21st-century Arthurian versions such as King Arthur and The Last Legion, this one emphasizes Arthur's ties with Rome and its empire. In season 1 of Kaamelott, several characters speak of adventures in Rome, but Arthur does not seem to like Roman art, food, etc.; however, in subsequent seasons, his Roman connections become important to his character and history. Season 6 tells the story of how Arthur, a Roman policeman, comes to understand his destiny and takes the crown of Britain.
Traditionally, Arthurian romance includes fantasy elements, but Astier may eventually intend to connect them to science fiction. He includes references to Stargate (Perceval travels through one in episodes in Livres 2 and 3) and Star Wars (in the Livre 3 Stargate episode, Perceval visits Tatooine and brings back a light-saber, which Arthur perceives as much like Excalibur; also, in Livre 1, Bohort, the minister of protocol, sometimes seems very much like C-3PO!). The first episode, entitled "Silbury Hill," suggests the presence of spiritual beings everywhere in Britain, but "Silbury Hill II" implies they are extraterrestrials and that Arthur and Léodagan know this. In Livre VI, we learn that Perceval was found as a baby in a crop circle, which, if these are made by space travellers from other planets, explains his affinity for stargates. Supernatural beings encountered by Arthur include Morgan Le Fay (not his sister, but involved with his eventual fate), Méléagant, the emissary of gods who seem to want to destroy human rulers, and his guide, the Lady of the Lake; at the beginning of Livre VI.2, a meeting of the gods whom the Lady of the Lake represents is depicted on Alpha Centauri, which implies that they at least are beings whose home is "the stars" rather than on earth. Thus, rather than recording relationships between humans and fairies, Kaamelott seems to posit relationships between Arthur and superior beings from other parts of the universe.
Like all Arthurian stories, Kaamelott twists history as well and adds its own view of where Arthur came from and what his reign means. Roman Britain had contributed armies, generals, and maybe an emperor to the Roman empire, but in Kaamelott, Britain is an aggregate of kingdoms that perceives Rome as an occupying force and Arthur perhaps as a Pétain for having made peace with the Romans. The enemies of the historical Britons in the 5th century were the Picts to the north, the Irish (aka the Scots), and the north Germanic tribes (Angles, Saxons, and Jutes) who had originally been brought in as mercenaries to fight the Picts. Arthur enters history as the victor of 12 battles between the British and the Saxons and is also often depicted fighting the Picts and the Scots in the north. Astier's Arthur, by contrast, apparently stays close to his fortress Kaamelott, where he is attacked by Angles and Saxons but also by Attila and his Hun, Burgundians, Ostrogoths, Vandals, Vikings, Visigoths—just about every "barbarian" people that was on the move in Europe then (though Attila was active earlier and the Vikings later), except for the Franks, ancestors of the French (though a historically Frankish leader, Chlodoric, does lead "barbarians" against Arthur). The Picts, however, represented by Arthur's mother-in-law, Séli, and the Irish, represented by a federated king, are Arthur's allies in Kaamelott. The geopolitics of Kaamelott resembles that of the comic book world of Asterix—a small, primitive "Celtic" society with its druid, warrior, and secret weapon, persisting on the edges of the Roman Empire—more than traditional English or American versions of the Arthur story.
