[Concerning the invisible god] some say that he is Aapep when he riseth up with a head bearing upon it [the feather of] Maat (Truth). But others say that he is Horus when he riseth up with two heads, whereon one beareth [the feather of] Maat, and the other [the symbol of] wickedness. He bestoweth wickedness on him that worketh wickedness, and right and truth upon him that followeth righteousness and truth.
