[2][3][4] After discovering a part of the novel in a manuscript of Prophecies of Merlin[5] kept at the bibliothèque de l'Arsenal, Arioli searched for other fragments of the story in libraries and archives across Europe.
[6] Mentions of Segurant start to appear at the end of the Middle Ages on Armorials of the Round Table which are lists of the fictional knights attending King Arthur's court "at the time where they swore on taking the quest of the Holy Grail on the day of Pentecost".
The story of Ségurant includes many characters and places of Arthurian legend, and seems to be particularly inspired by the Lancelot-Grail and Prose Tristan novels.
[7] His name may be related to Latin word securus, meaning safe or secure, but also to Germanic legendary characters Sigurd or Siegfried, who are also dragon slayers.
But Morgan le Fay, fearing that the knight may foil her plan to seize the kingdom of Logres, summons a dragon during the tournament – an incarnation of Lucifer himself.
Even though the main elements of Arthurian legend are present, Segurant's story is singular as there is no mention made of the quest for the Grail and with his disdain for the strict rules of courtly love.
