Having established that in a calendar for the year Rei glyphs were used in connection with the cardinal points (solstices, equinoxes), it is time to once again take up the question about what meaning GD13 glyphs have.

The four seasons, once originating from the cardinal points, is not a state of nature which 'primitive' man accepted without deep thinking.

In South America, for example, there were myths which referred to the beginning as either a time when there was constant darkness or when there was constant light, and how it came about that this still world started to move around as we can observe it today.

Other myths described how the seasons were moving too slowly or running to fast, as when Maui had to slow the sun down in order to give his wife enough time to cook their meals.
