In the Egyptian view below, describing the path of the Sun in daytime, there are 2 holes, one for 'birth' in the morning (in the east) and another in the evening (in the west):

The artist has meant us to be observant. For instance are the arms in the west integral parts of the woman of the background, whereas the arms in the east are separate entities.

In the middle of the panel the serpent of the Sun is rising and beyond noon the Sun 'eye' has a dot (a pupil) in its center - perhaps to indicate the rainy half of the day, when fruits were forming.

The form of the hole in the west is not circular - more like the shape the Moon could have had in the Polynesian night Hua. The same outline occurs, however, also in the shape of the nightside Earth:

Earth and Moon were regarded as sisters.

The Egyptian path in nighttime was not straight but arching high above:

Shu, the god of feathers (air), lies upon the ground stretching out the fingers of his left hand towards dawn.
