Which figure is known for instructing great heroes in mythology?

Chiron is recognized in mythology as a wise centaur who served as an educator and mentor to many of the great heroes, including Achilles, Hercules, and Asclepius. His unique combination of knowledge in medicine, music, and various arts made him an ideal teacher for those destined for greatness. Chiron’s teachings are often depicted as pivotal moments in the training and development of these heroes, shaping their skills and character. This role distinguishes him from the other figures listed, as Hercules and Achilles are celebrated as heroes themselves rather than as educators, while Hephaestus is known for his craftsmanship and inventions rather than for instructing heroes. Chiron's reputation as a wise and skilled mentor solidifies his role in helping to create some of the most renowned figures in Greek mythology.
