Although the show was at first 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.
