The Fly And The Draught Mule
A Fly sat on the axle-tree of a chariot, and addressing the Draught-Mule
said, "How slow you are! Why do you not go faster? See if I do not
prick your neck with my sting." The Draught-Mule replied, "I do not
heed your threats; I only care for him who sits above you, and who
quickens my pace with his whip, or holds me back with the reins. Away,
therefore, with your insolence, for I know well when to go fast, and
when to go slow."
