An African (Ashanti) myth records that God separated himself from Mankind after an old woman carelessly injured him with her pestle. In a futile attempt to reunite heaven and earth, the old woman gathered together all her children, and stacking large numbers of mortars, one on top of another, constructed a tall tower.
Only a single mortar was needed to bridge the gap between heaven and earth, but because there were none left, the old woman ordered that the bottommost mortar should be removed and placed at the top. Of course, the tower collapsed and many people lost their lives.
