Thoth has played a prominent role in many of the Egyptian myths. Displaying his role as arbitrator, he had overseen the three epic battles between good and evil. All three battles are fundamentally the same and belong to different periods. The first battle took place between Ra and Apophis, the second between Heru-Bekhutet and Set, and the third between Horus, the son of Osiris, and Set. In each instance, the former god represented order while the latter represented chaos. If one god was seriously injured, Thoth would heal them to prevent either from overtaking the other.
