Lozi mythology
The main function of Lozi mythology is to show that the original Lozi people (the Luyi or Luyana) were dwellers on the Barotse Floodplain of the upper Zambezi River and that they are, therefore, entitled to claim unchallenged title to that homeland. Secondly, Lozi mythology gives legitimacy to the Lozi kingdom's foundations, by linking the monarchy and the people to a creator god, whom the Lozi call Nyambe.
Nyambe's wife was Nasilele (which means "she who is associated with long things") and his mother was Ngula (which means "she who is pregnant"). Nyambe is said to have created both his wife and his mother. He is also said to have created everything else that exists, including the heaven, the Earth and all the plants and animals.
The founding myths
The Lozi founding myth is not cast in stone, there are several versions of it, depending on who is telling the story. Like any other oral tradition, it has changed with the passage of time, but there are some elements that do not change, such as the name of the creator god, the name of the first man, and the name of the first sovereign.
