This is one of a series of short fables by G.E.Lessing. I have entered it in the original German as Jupiter und Apollo. An (approximate!) English translation is below.

Jupiter and Apollo.

by G.E.Lessing

    Jupiter and Apollo were contending which of them was the best archer. "Let us put it to the test!" said Apollo. He bent his bow, and struck the center of the observed target so accurately that Jupiter saw no possibility of outdoing him.
    "I see," he said, "that you really shoot very well. I shall have difficulty to do better. Still, I will try it another time."
