chunk: Book V is centered on the virtue of Justice as embodied in Sir Artegal.
  Book VI is centered on the virtue of Courtesy as embodied in Sir Calidore.The Faerie Queene owes, in part, its central figure, Arthur, to a medieval writer, Geoffrey of Monmouth. In his Prophetiae Merlini ("Prophecies of Merlin"), Geoffrey's Merlin proclaims that the Saxons will rule over the Britons until the "Boar of Cornwall" (Arthur) again restores them to their rightful place as rulers. The prophecy was adopted by the Welsh and eventually used by the Tudors. Through their ancestor, Owen Tudor, the Tudors had Welsh blood, through which they claimed to be descendants of Arthur and rightful rulers of Britain. The tradition begun by Geoffrey of Monmouth set the perfect atmosphere for Spenser's choice of Arthur as the central figure and natural bridegroom of Gloriana.
