These legends are strongly medieval in flavor. Magic enchantments and miracles abound, yet despite the fantastic elements there is a hard basis of reality underlying these tales. Not a factual reality, but the kind that fiction presents. The world here is coherent: it makes sense. King Arthur is the center of that world, and by his valor, his strength, and his high purpose he collects an assembly of knights who share his purpose. These knights vie with one another to test their courage, might, and nobility. They undergo temptations that they must resist if they are to perform great deeds. Above all, they must be unselfish, for they are serving a power greater than themselves, the ideal of Logres, the holy realm. Logres is a place where faith works miracles and where the power of Heaven supports the weak and the humble. Frequently in these stories a knight fails to live up to this communal ideal, but he must pay for it in the end. Arthur begets Modred on his half sister adulterously, and Modred is the agent of Arthur's ruin. Launcelot and Guinevere destroy Logres with their love affair. And Tristram through his love for King Mark's wife endures exile and death.
There seems to be a general logic to the magic spells and miracles of these tales. Enchantments are used to test the knights of the Round Table. When another person suffers from a spell it takes a knight to redeem that person. When a knight undergoes enchantment it is to test his integrity. To witness a miracle a knight must have passed his tests of character. Thus wonders in these tales are not just the furnishings of an age of faith, for they serve to reveal a man's character.
This is our first example of a band of heroes fighting for abstract principles of justice, honor, and purity. These knights have serious flaws — pride, lust, rashness, vengefulness — but they rise above their faults in the contribution they make to Logres. Each knight is tested for his weaknesses. Only the holiest of knights, Sir Galahad, is allowed to drink from the Holy Grail. The Grail Quest is the summation of Logres, the period when each knight sets forth on an unselfish mission.
These assorted tales carry an extremely important insight — that a man's self-respect does not depend on external qualities, such as wealth, position, physical strength, or size. It depends on his private integrity and his valor in pursuing great goals. This is the kind of insight that builds civilizations.
