Henry the Young King
According to his later "vida" (a romanticised short biography attached to his songs), Henry II believed Bertran had fomented the rebellion of his son Henry the Young King. As a result, Dante Alighieri portrayed him in the "Inferno" as a sower of schism, punished in the ninth bolgia of the eighth circle of Hell (Canto XXVIII), carrying his severed head like a lantern. Gustave Doré depicts this in his illustrations to the "Divine Comedy."
