Hello. You did not inform the theater play to which this question refers, which makes it impossible to answer it exactly. However, I will try to help you in the best possible way.
The oral tradition refers to the culture of passing information orally between generations through songs, texts, short stories and even proverbs. This allows the icons and ideals of a generation to be kept alive over the years. In the case of the question above, oral tradition may have an influence on the scene shown by presenting concepts related to the canyon on the cliff, allowing farmers to draw their own conclusions based on what they heard about the Canyon.
