Figures 25

Pillar of the winter solstice of the Third Period. On the upper part this shows half of a small window where, as can be seen in the reconstructed Figure 25a, the sun appeared for a moment at the winter solstice in the form of a vertical, luminous ray, This was the case since the sunrise was observed from a visual angle of approximately 23* 30'.
