Many generations ago a great flood caused the death of all the people in the world, except for one pregnant woman. She prayed that her child might be a boy. Her prayer was answered and she gave birth to a son whose name was Uacatan. When he had grown up he took his mother as his wife and from this union have sprung all the Mandaya.
