Now a certain astronomical fact was observed even in the most ancient times. Many thousands of years before the Christian era, the Egyptians knew that after a period of 72 years the fixed stars in their apparent course gain one day on the Sun. It seems to us, does it not, that the fixed stars revolve and the Sun too revolves, but that the latter revolves more slowly, so that after 72 years the stars are appreciably ahead. This is the reason of the movement of the Vernal Point (the Spring Equinoctial point); namely, that the stars go faster. The Spring Equinox moves further and further away, the fixed star has altered its place in relation to the Sun. Briefly, the facts are that if we notice the path of a fixed star and notice the point where the Sun stands over it, we find that at the end of 72 years the star occupies the same position on the 30th December, while the Sun only reaches that point again on the 31st December. The Sun has lost a day. After a lapse of 25,920 years this loss is so great, that the Sun has described a complete revolution and once again is back upon the place we noted. We see therefore that in 72 years the Sun is one day behind the fixed stars. Now these 72 years are approximately the normal life period of Man, and they are composed of 25,920 days.
