Atenism offers a very good example of the exclusivity of presence. We find it in the moment of dawn and dusk.
The religious ideas with which Akhenaten grew up were those of the New Solar Theology. It is to be found in hymns and rituals and in the Books of the Netherworld of Dynasty. At its core is the daily course of The Sun, which guarantees the continued existence of the cosmos. The Sun god renews his creation every morning, but he also descends nightly into the netherworld, where his resurrecting light wakes the dead to new life in the depths of The Earth.
The entire cosmos is dependent upon light and the sight of the god, but this light must be continually regenerated in the darkness; it must overcome dangers and hostile forces whose most powerful embodiment is the great serpent Apopis/Apep/Apophis. These menacing forces are defeated, and the New Solar Theology reflects a deep trust in the reliability of The Sun.
However, by identifying the diurnal phase of the daily cycle of The Sun with the universal deity (Aten), Atenism was incapable of dealing with something very important to the ancient Egyptians: a good afterlife. The nocturnal phase was not present. The netherworld and Osiris were left out of the picture, although the Duat was mentioned. The Aten "rested" in the West and as it were immediately "dawned" in the East, from "horizon" to "horizon".
