When the man was first created, God made him all of the gold. But when God called, he did not answer. So, God made a silver man, but he still did not speak. Next, God tried with iron. Still, Man kept silent. In the end, God took the ash from a fire-place and the droppings left by some chicken and with these, he made Man, and called, “Man, Man.” And for the first time, Man spoke.
Before long, however, God’s anger was gone and He felt pity for Man. So, he sent a crow with an elixir of life to revive Man. But the crow drank the elixir itself and God was angry when He learnt what it had done. He took a fireband and threw it at the crow so that it was burnt and it has remained black ever since. After Man had been brought back to life, God called an ox and asked him to go and tell Man to take his food once a day. The ox went to Man but told him to eat three times daily. When the ox came back, God asked him if he had conveyed the message.”Yes,” said the ox, “I have told Man to eat thrice every day.”
God was angry again. He said to the ox; “You must go back to Man and feed him yourself. Except on the days of the new moon and the full moon, you must work for him so that he will have enough to eat three times a day.”This is why the ox is made to work on all days, except on the days when the moon is new and when it is full.
