Hawk. The hieroglyphic and type of the Soul. The sense varies with the postures of the bird. Thus when lying as dead it represents the transition, larva state, or the passage from the state of one life to another. When its wings are opened it means that the defunct is resurrected in Amenti and once more in conscious possession of his soul. The chrysalis has become a butterfly.
