Read the passage from “The Beginnings of the Maasai.” Neiterkob was confused at first. It was one thing for an eruption to send cows flying up into the sky, but it was another problem entirely to get them down to earth again. The wise god knew how to solve the problem. Enkai grew a giant fig tree out on the plains. The tree grew rapidly, and its branches grew so high that they reached up into the heavens. One by one, Enkai sent the cattle walking down branches of the fig tree, all the way down to the roots at the ground. My father and our people accepted the cattle and began to herd them with the sticks that Enkai had given us. Now, the rest of the tribe calls my father the “Beginner of the Earth” because he mediates between Enkai and our tribe, just as he did when the cattle returned from the sky.
