Polar immortality
The archaeoastronomer E.C. Crupp:
For the ancient Egyptians, the circumpolar zone was the realm of immortality, the home of the Imperishable Stars. In following their circular paths around the north celestial pole, those that never rose and never set became synonymous with eternal life. (Echoes of the Ancient Skies, 104)
