Here's what we can clarify:
* There is no official list of "mystery cycles" that are universally accepted. The concept is more of a literary observation than a hard-and-fast category.
* Many medieval romances survive, but often in fragmented form. Manuscripts were copied and recopied, with parts being lost or modified over time.
* Different scholars might categorize cycles differently. One scholar might consider a group of romances a "cycle," while another might see them as separate works.
That being said, some of the most commonly recognized "cycles" of medieval French romances include:
* The Arthurian Cycle: This is the largest and most well-known, focusing on King Arthur, the Knights of the Round Table, and their adventures.
* The Matter of France: This cycle revolves around the legendary deeds of Charlemagne and his knights, particularly against the Saracens.
* The Matter of Britain: This encompasses stories of British kings and heroes, like King Lear and the legendary giant Gogmagog.
* The Alexander Romance: This cycle follows the conquests of Alexander the Great, blending history with fantasy.
It's important to note that these cycles are not always distinct and can overlap. For example, some Arthurian romances feature characters and themes from the Matter of France.
In conclusion, while it's difficult to say exactly how many "mystery cycles" remain intact, we can say that many medieval French romances survive, both in whole and in part. These works offer valuable insights into medieval culture, literature, and imagination.
