In Greek mythology, a centaur is a creature that is part human and part horse. They are often depicted with the upper body of a human and the lower body of a horse. Centaurs embody the duality of human nature, representing both the wild and the civilized aspects of existence. Known for their strength and endurance, they are often portrayed as either wise and noble, like Chiron, or as unruly and chaotic. This dichotomy reflects themes of instinct, reason, and the struggle within human nature.
