Apep was seen as a giant snake or serpent leading to such titles as "Serpent from the Nile" and "Evil Dragon". Some elaborations said that he stretched 16 yards in length and had a head made of flint. Already on a Naqada I (c. 4000 BC) C-ware bowl (now in Cairo) a snake was painted on the inside rim combined with other desert and aquatic animals as a possible enemy of a deity, possibly a solar deity, who is invisibly hunting in a big rowing vessel.
