We had agreed that we would include in the book an ancient creation myth known in southern Sudan. In the story, God, pleased with his greatest creation, offers the first Dinka man a choice of gifts: on the one hand, the cattle, visible and known, an animal that can feed and clothe him and last for ever; on the other hand, the What. The man asks God, "What is the What?", but God will not reveal the answer. The What was unknown; the What could be everything or nothing. The Dinka man does not hesitate for long. He chooses the cattle, and for thousands of years Dinka lore held that he had chosen correctly; the cow is thus sacred in southern Sudanese culture, the measure of a family's wealth and the giver of life.It was not until the torment of the southern Sudanese in the 20th century that the Dinka began to question this choice. What was the What, they wondered, and speculation about the answer abounded: was it technology? Education? Sophisticated weapons? Whatever the answer, it was assumed that the Arabs of the north - who, legend had it, had received the What - might have got the greatest of God's gifts, and were using this What to inflict unending pain upon the southern Sudanese.
