After Geoffrey of Monmouth, there were lots of writers who used his book as a source for their own stories.

The second important writer is Wace. He wrote Roman de Brut in the 12 th century. He added the legend of the knights of the Round Table and gave the King Arthur's sword the name Excalibur1.

The third important writer is Chr├ętien de Troyes. He was a French novalist. He mentioned the Holy Grail for the first time in the story Perceval , about one knight of the round table. He also came up with Lancelot and the affaire between Lancelot and Guinevere1.

After de Troyes you've got the Vulgate Cycle . The Vulgate Cycle is a collection of stories probably written by French monks in the early 13 th century. The Vulgate Cycle adds new stories to the Arthurian legend. Lancelot gets the leading role and Arthur and Gawain seem to move to the background. In the Vulgate Cycly it is the first time that the affair of Lancelot and Guinevere is seen as the direct reason for the fall of King Arthur1.

Shortly after the Vulgate Cycle the Post Vulgate Cycle was written. This is an addition to the Vulgate Cycle and the spotlight moves from Lancelot to the Holy Grail1.

Thomas Malory wrote the story which is most popular; Le Morte D'Arthur . He didn't really tell new things, but he made the story popular. Romantic writers made the book popular through whole Europe2.

The story Idylls of A King by Tennyson, is completely based on Malory's Le Morte D'Arthur . The only difference is the way the story is told. Tennyson changed the story into a poem in lovely old English3.
