The Arthurian Legends are a cycle of stories that has been shaped and passed down through over fourteen hundred years of English history. The legend of King Arthur tells of the adventures of an early king of Britain and the knights and ladies who made up his royal court at Camelot. It tells of a world filled with warriors armed with lance, sword, and armor. It speaks of jousts, tournaments, wizards, falconry, enchantresses, damsels in distress, wars, quests, and the code of chivalry. It is a legend that talks of a great king who came to throne from what seemed to be nowhere and of a noble idea that ends in tragedy. I suppose, the version we know best is the one that was composed in the 15th century. This is the great English version of the story, compiled out of earlier versions by the creative genius of a rather mysterious and cryptic figure, the knight, Sir Thomas Malory.
The main characters in romance literature are larger than life. Romance literature is concerned with the feats of kings, queens, and knights, not with common, ordinary people. They follow a code of chivalry. A main character in romance literature is braver, nobler, and more honorable than an ordinary human. Oftentimes, the medieval period in general, and King Arthur in particular, have an air of mystery, romance, fantasy, and adventure that are popular themes in all times and cultures. We see King Arthur's magical powers when Sir Bedivere throws Excalibur into the lake, causing lightning to strike in the splendor of the moon. Main characters in romance literature are god-like characters that have no fear, retain their youthful qualities as they age, and never become a victim of sickness. Sometimes a main character in a romance is motivated by love.
Morte d" Arthur is a mysterious, magical, and perhaps realistic view of the medieval period. If the name of King Arthur is mentioned, I suppose what comes to mind is not so much one person as a whole array of characters and themes, a montage so to speak.
