[3] A fanciful tale of the brothers begins with Kerbogha (Carbaran), a Turkish general and Atabeg of Mosul, conceding defeat at the siege of Antioch and, along with a number of prisoners, returns the body of Brohadas,[4] the son of the sultan of Persia, Rukn ad-Denya wa’d Din to Kermanshah.
This story begines in the Chanson de Geste, an early French epic poem: So Carbaran escaped across the plains of Syria He took only two kings in his company He carried away Brohadas, son of the Sultan of Persia Who had been killed in the battle by the clean sword Of the brave-spirited good duke Godfrey
He selects Richard of Caumont[7] (brother of Walo II of Chaumont-en-Vexin) who consents, in exchange for his freedom and that of his companions, to do battle with Goliath of Nicaea and Sorgalé of Mecca.
As they are crossing the “land of Abraham,” presumably modern Israel, a dragon attacks Arnold and is slain by Baldwin.
The story continues as Kerbogha’s nephew, son of Queen Florie [whose identity is unknown] is carried off by a wolf.
