Several myth cycles have been featured here before, most often the Cthulhu Mythos, of course, but there have also been mentions of Norse Mythology and more recently the Epic of Gilgamesh. Now it is time for some mythology that is often, sadly, ignored by most:

African mythology.

The fact that African mythology is often ignored in cultural studies is tragic, since this continent offers an astoundingly divers and rich treassure of tales that, due to the nature of human origin, go back longer than anywhere else on earth.
Here is one great example of African mythology: The Mwindo Epic, a tale by the Nyanga people of the Congo:

Also of note is the way the epic is traditionally told (this is according to the Wikipedia, so accurracy may be flexible):

The Mwindo Epic varies from typical oral myths in that it is not only spoken, but performed among gatherings of locals. The myth is performed mostly by a single bard wielding a calabash made into a rattle and donning various bells and other forms of noisemakers. To tell the story properly the bard acts out all the parts and does not refrain from being very animated in his dances and acting. It is not unusual for the bard to throw in some narrative not native to the story detailing his own life and his own personal experiences. The narrator is usually accompanied by four younger men who play on a percussion stick.

Audience participation is important. The audience will often sing along with the narrator and the percussionists during the songs, and repeat certain lines of the story while the narrator pauses between sections. The bard is often shown appreciation by the audience with applause, yells, and gifts.
