It sounds like it was written in 19th-century English, too--that would be neat, I bet!
BTW while I was in college I had a nice opportunity to take a class on Arthurian literature under a Tolkien scholar who was in our English Department. We surveyed the major treatments of Arthur in literature and film--here is our syllabus:
Week 1: Introduction and Marie de France (Sir Lanval)
Week 2: Chretien de Troyes (Yvain)
Week 3: Sir Gawain and the Green Knight
Week 4: Sir Alfred Lord Tennyson (Gareth & Lynette
Week 5: Mark Twain (Connecticut Yankee in King Arthur's Court
Week 6: T.H. White (The Sword in the Stone)
Week 7: Selections from Sword in the Stone and Camelot
Week 8: Marion Zimmer Bradley (The Mists of Avalon
Week 9: Selections from Excalibur, etc.)
The "etc." in the last week turned out to be Monty Python :)
