, darkness.... This word Is composed of the two contracted roots It  is remarkable in its figurative and hieroglyphic sense.
In its figurative sense, it is a compressing, hardening movement; in its hieroglyphic, it is a combat, a violent opposition between the con­trary principles of heat and cold. The root expresses a violent and disordered movement caused by an inner ardour which seeks to distend. The root depicts on the contrary, a sentiment of con­traction and tightening which tends to centralize. In the composition of the wrord it is the compressive force which prevails and which en­chains the inner ardour forced to devour itself. Such was the idea that the Egyptian priests formed of darkness.
