Apep's hieroglyphs describe the great resonances that cause the Corona to absorb energy increasing in size. (Resonance is absorption of energy.) The long body of the snake describing the absorption of energy from the galaxy being controlled by God, Atum explains this as he is male and represent the process of negative charge induction toward the corona.
Atum is Electromagnetic Induction and is shown controlling the Suns Corona as the Snake. The hieroglyphs surrounding them explain how God monitors the electric potential and maintains the Suns Corona through control and watching of negative charge induction.
