Spenser's The Faerie Queene

The Redcrosse Knight and his lady Una travel together as he fights the monster Errour, then separately after the wizard Archimago tricks the Redcrosse Knight into thinking that Una is unchaste using a false dream. After he leaves, the Redcrosse Knight meets Duessa, who feigns distress in order to entrap him. Duessa leads the Redcrosse Knight to captivity by the giant Orgoglio. Meanwhile, Una overcomes peril, meets Arthur, and finally finds the Redcrosse Knight and rescues him from his capture, from Duessa, and from Despair. Una and Arthur help the Redcrosse Knight recover in the House of Holiness, with the House's ruler Caelia and her three daughters joining them; there the Redcrosse Knight sees a vision of his future. He then returns Una to her parents' castle and rescues them from a dragon, and the two are betrothed after resisting Archimago one last time.
