An astronomical phenomena which is defined by the long-term shift of the stars in our sky caused by a wobbling of the earth as it spins on its axis. It is a pre-cession, instead of a pro-cession, because it appears as if we are traversing through the constellations in reverse, one complete cycle every 25,920 years. According to Liber Legis I:49, the Equinox of the Gods took place on the Spring Equinox of 1904 as the Earth entered Aquarius. Therefore one can calculate each Aeon of 2160 years as follows:

• 24,016 BCE Aquarius begins
• 21,856 BCE Capricorn begins
• 19,696 BCE Sagittarius begins
• 17,536 BCE Scorpio begins
• 15,376 BCE Libra begins
• 13,216 BCE Virgo Begins
• 11,056 BCE Leo Begins
• 8,896 BCE Cancer begins
• 6,736 BCE Gemini begins
• 4,576 BCE Taurus begins
• 2,416 BCE Aires begins
• 256 BCE Pisces begins
• 1,904 CE Aquarius begins
• 4,064 CE Capricorn will begin
