chunk: Book I is centered on the virtue of Holiness as embodied in the Redcrosse Knight. He and his lady Una travel together as he fights the dragon Errour, then separate as the wizard Archimago tricks the Redcrosse Knight in a dream to think that Una is unchaste. After he leaves, the Redcrosse Knight meets Duessa, who pretends to be captured in order to trap him. Duessa leads the Redcrosse Knight to captivity by the giant Orgoglio. Meanwhile, Una overcomes peril, meets Arthur, and finally finds and rescues the Redcrosse Knight from his capture, from Duessa, and from Despair. Una and Arthur help the Redcrosse Knight recover in the House of Holiness; there the Redcrosse Knight sees a vision of his future. He then returns Una to her parents' castle, rescues them from a dragon, and the two are betrothed after resisting Archimago one last time.
