Coffin Texts
The Coffin Texts imply that Apep used a magical gaze to overwhelm Ra and his entourage. Ra was assisted by a number of defenders who travelled with him, including Set and possibly the Eye of Ra. Apep's movements were thought to cause earthquakes, and his battles with Set may have been meant to explain the origin of thunderstorms. In one account, Ra himself defeats Apep in the form of a cat.
