A lion used to prowl about a field in which Four Oxen used to dwell. Many a time he tried to attack them, but whenever he came near they turned their tails to one another so that whichever way he approached them he was met by the horns of one of them. At last, however, they fell a-quarreling amoung themselves, and each went off to pasture alone in a separate corner of the field. Then the lion attacked them one by one and soon made an end to all four - Aesop, Six century B.C.
