Which figure in Greek mythology is closely associated with trickery and cunning?

Odysseus is indeed closely associated with trickery and cunning, making him the correct choice for this question. He is most famously depicted in Homer's "Odyssey," where his cleverness plays a crucial role in his adventures and ultimate return home after the Trojan War. One of the most notable examples of his cunning is the use of the Trojan Horse, a deceptive stratagem that led to the fall of Troy. Throughout his journeys, Odysseus often relies on his wits to overcome challenges, outsmart enemies, and navigate treacherous situations.

The other figures listed have different associations. Heracles is primarily known for his strength and heroic feats, often emphasizing physical prowess rather than cunning. Persephone relates more to themes of life, death, and the seasons, particularly in her role in the myth of Hades. Daedalus is an inventor and craftsman recognized for his intelligence and creativity, particularly in crafting the Labyrinth for the Minotaur; however, he does not embody the same level of trickery and cunning as Odysseus. Thus, Odysseus stands out as the quintessential trickster figure in Greek mythology.
