Like the Mirrors for Princes, this could be used to convey advice to readers. For instance, in most romances, Arthur's greatest military achievement – the conquest of the Roman Empire – is placed late on in the overall story. However, in Malory's work the Roman conquest and high point of King Arthur's reign is established very early on. Thus, everything that follows is something of a decline. Arthur, Lancelot and the other Knights of the Round Table are meant to be the paragons of chivalry, yet in Malory's telling of the story they are doomed to failure. In medieval thinking, only God was perfect, and even a great figure like King Arthur had to be brought low. For the noble reader of the tale in the Middle Ages, this moral could serve as a warning, but also as something to aspire to. Malory could be using the concept of Fortune's Wheel to imply that if even the greatest of chivalric knights made mistakes, then a normal fifteenth-century noble didn't have to be a paragon of virtue in order to be a good knight.
