chunk: Ruggiero is taken captive by the sorceress Alcina and has to be freed from her magic island. He also has to avoid the enchantments of his foster father, the wizard Atlante, who does not want him to fight. Finally, Ruggiero converts to Christianity and marries Bradamante.
  Rodomonte appears at the wedding feast and accuses him of being a traitor to the Saracen cause, and the poem ends with Ruggiero slaying Rodomonte in single combat. Ruggiero and Bradamante are the ancestors of the House of Este, Ariosto's patrons, whose genealogy he gives at length in canto 3 of the poem.
  The epic contains many other characters, including Orlando's cousin, the paladin Rinaldo, who is also in love with Angelica; the thief Brunello; the Saracen FerraĂš; Sacripante, King of Circassia and a leading Saracen knight; and the tragic heroine Isabella.
