Fromont, the nephew of Hardré, the villain who was killed by Ami in
Amis et Amiles, wishes to avenge his uncle's death. He comes to
Blaye and suborns a pair of
serfs to kill the lord, Girart, son of Ami, and his wife, Hermenjart, in their sleep. He takes control of the town, but his position is not secure so long as Girart's infant son, Jordain, still lives in the care of his godparents, Renier and Eremborc, lord and lady of Valtamise. Fromont attempts to trick Girart into handing the boy over. Failing that, he bribes him with money, but Girart refuses and is thrown into a dungeon. His wife soon follows him. They remain imprisoned for thirteen months. Eremborc has her tongue cut out. Renier and Eremborc decide to substitute their own son for Jordain. Fromont decapitates the child himself, to the horror of his own nobles. Angels take the innocent's soul to heaven. When he is old enough, Jordain, who is being passed off as Renier's son, is sent to Blaye for training as a
knight. Fromont hates him because he looks like Girart. After he strikes Fromont, he is forced to perform menial tasks. When Fromont threatens his life, he returns to Valtamise, where Renier reveals to him the truth. Jordain, Renier, Eremborc and 400 of Renier's vassals head off to Blaye to enact vengeance on Fromont. Jordain cuts off his nose, but he escapes. During the battle that follows some time later,
Charlemagne is passing by on the
way of Saint James. His son,
Lothair, impetuously joins the battle, attacks Renier and is killed by Jordain. Charlemagne must now side with Fromont and the men of Valtamise retreat. Having lost his own nose, Fromont has the noses of the two serfs cut off also. Jordan, Renier and Eremborc take ship on the
Gironde and head for the open ocean. They are attacked by
Saracen pirates. While Jordain escapes, his godparents are captured and taken to Mount Bruiant, where they are sold as slaves to King
Salatien. Floating on a piece of wood at sea, Jordain deliberately injures himself to draw blood so that the sea will be forced to disgorge him ashore, since the sea cannot stand blood. He is rescued by a fisherman, who directs him to the nearby city of Marcasille. There in the town square he accepts the challenge of King Mark to a joust. He catches the eye of the Princess Oriabel, who outfits him as one of her knights. He eventually reveals his true lineage to her. Marcasille is attacked by a pagan army, whose champion Brumadant defeats five champions sent against him. With Oriabel's blessing, Jordain defeats him. The pagan army attacks, but King Mark's forces rout them. Jordain and Oriabel are married. After she becomes pregnant, Jordain decides to go in search of his godparents. She accompanies him and gives birth at sea, whereupon a storm threatens the ship and its company has her thrown overboard in a chest with money, fine cloth and a letter of explanation. Jordain continues to the Christian city of Orimonde, where he baptises his new daughter Gaudisce. Oriabel drifts ashore near
Palermo. The archbishop, out on a hunt, notices her and revives her lifeless body with a balm. She becomes an
anchorite. Jordain, meanwhile, leaves the service of King Cemayre to search for her. He sails to Palermo and goes to a monastery to pray. Oriabel overhears him and the two are reunited. They move to continue the search for Renier and Eremborc. The archbishop bestows on them rich gifts and his blessing. When Jordain inadvertently anchors in a port held by Saracen pirates, a sea battle ensues. He is captured, but his men rescue him. Renier, meanwhile, has obtained his freedom from Salatien. Neither recognises the other as they approach each other on the road. Only their respective battle cries, "Blaivies!" and "Valtamise!", avert a disaster. Jordain, Renier and Oriabel return to Orimonde to collect Gaudisce. King Cemayre's wife, however, has had her carted off to
Constantinople and abandoned because she was more beautiful than her own daughter. In Orimonde, the queen tells to Jordain that his daughter is dead, but Gaudisce's former guardian, Josselme, admits the truth. In Constantinople, Gaudisce is rescued by a nun. As she grows, the king's son, Aly, falls in love with her. She resists him. When Jordain arrives in the city, he learns of the prince's failed courting and goes to see the girl. He recognises his daughter and marries her to Aly. The whole party now goes through Italy to the court of Charlemagne at
Orléans, where Renier intervenes to restore Jordain to the emperor's favour. Finally, Jordain returns to Blaye and besieges it. Advised by his nephew Foucart to attack while the besiegers are weary from travel, Fromont launches a night sally and is captured. His demoralized men surrender and the inhabitants recognise their lawful lord. Fromont, Foucart and the two serfs are dragged to death. A messenger from Constantinople arrives with the news of the king's death. Aly and Gaudisce go to Constantinople to rule it. After some time, King Mark dies. Jordain gives Blaye to Renier and he and Oriabel go to rule Marcasille. ==Notes==
