Penelope demonstrates cleverness when she calls for the suitors to hold a contest to string Odysseus's great bow. This act showcases her intelligence and resourcefulness, as she devises a plan to delay the suitors while also creating a situation that might allow her to reunite with her husband.
A character who has a similar trait is Odysseus himself. He is known for his cleverness and cunning throughout the "Odyssey," using his wits to outsmart foes and navigate challenging situations, much like Penelope does in this context.
