The lion, the fox, and the jackass
The Lion, the Fox and the Jackass entered into an agreement to assist each other in the chase. Having secured a large booty, the Lion on their return from the forest asked the Jackass to allot his due portion to each of the three partners in the treaty. The Jackass carefully divided the spoil into three equal shares and modestly requested the two others to make the first choice. The Lion, bursting out into a great rage, devoured the Jackass. Then he requested the Fox to do him the favor to make a division. The Fox accumulated all that they had killed into one large heap and left to himself the smallest possible morsel. The Lion said, "Who has taught you, my very excellent fellow, the art of division? You are perfect to a fraction. He replied, "I learned it from the Jackass, by witnessing his fate."
Happy is she who learns from the misfortunes of others.
