'The Lion and the Mouse', an illustration by JVL from Aesop's Fables, Jonathan Cape, 1989.
This is a fable about a lion who caught a mouse with the intention of eating him. The mouse begged for his life, claiming that he was far too small for a lion to eat and that he simply would not be a decent meal for such a mighty beast. The lion thus freed the mouse. Some while later the lion was caught in a net by trappers. The mouse saw this and immediately started to gnaw at the ropes of the net, eventually freeing the lion from his bonds. It is fable that shows that the weak and humble are capable of helping the strong and powerful if those who are strong are compassionate and supportive to the weak.
