In Iliad, the horse on the battlefield seemed to be extremely sensitive and fickle, and the charioteer who wanted to control the chariot well should be rational and smart. The description of the "chariot-charioteer" in Iliad formed a theme about the hero’s self-control, which inspired Platon’s the Chariot of the soul, and contributed to the symbolic relation of the horse and the dual instincts of human nature in western culture. As a work having a long tradition of oral literature, the description of horse and chariot racing in Iliad reflected the Homeric athletic culture being formed, horse was a symbol of wealth, the champion of chariot racing was the crown of honor which heroes sought for, which promoted the development of the Olympic culture during the Archaic and Classical Period. In addition, the horse myth in Iliad contained abundant information about the ancient religionary formation in Greece, presented the process of the struggle and integration between Zeus, the foreign sky god, and Poseidon, the local god, and expressed the humanistic thoughts in the new religion of early Greece.
