Death spake unto the gods saying, 'What has become of him who has created us?'--'Being afraid of thee, he has entered this (earth),' they said. He spake, 'Let us search for him, let us gather him up for I shall not injure him.' The gods gathered him from out of this (earth): that part of him which was in the water, they gathered as water, and that which was in this (earth, they gathered) as clay. Having gathered together both clay and water, they made a brick, whence a brick consists of both clay and water.
