Know the Time and what must be Done


Many ancient ruins demonstrate that the people who constructed them had not only a special regard for celestial bodies and mathematics, but also a spot-on accuracy. From Egypt to Mexico, there is no doubt that past civilizations were involved in incredibly complex space calculations, mathematics and architectural endeavours. Although many historians and archaeologists debate exactly what these civilizations did intentionally and what they did by mere chance, here are a few examples of how ancient architecture was created with mathematics and the cosmos in mind.

The Mayans had a sophisticated calendar, losing only one day in 6000 years. Their predictions of solar and lunar eclipses were incredibly accurate. As many have heard, they predicted a date that they believed would be the end of the world. This date, translated to our calendar, is on December 23, 2012. Although unlikely, the world is predicted to suddenly end in about seven years (if we have just translated the meaning of their calendar correctly).

The Mayans did have some rationale behind this number. This date marks the time in the precessional cycle of the earth that we will move out of the constellation of Pisces and on to the age of Aquarius.

What is global precession? I’m glad you asked. Everyone knows that the earth spins on its axis while it revolves around the sun. Most remember from grade 10 science class that the earth’s axis is not perfectly vertical, but rather tilted about 23.5 degrees. However, the axis is not always this way, as it slowly varies from about 24.5 degrees to 22.1 degrees, making a complete cycle every 41,000 years.

While it is moving in this way, due to varying gravitational forces, the axis wobbles (precesses) in a clockwise circle. Just imagine the way the axis of a top spins as it begins to fall. So, the angle of the earth stays the same (or somewhere within its three degree variance), but the direction in which it points changes. For example, our current North Star is Polaris (or Ursae Minoris), as the North Pole points towards this star. However, approximately 13,000 years ago, the North Pole would have pointed towards the star Vega, as it will do again in about another 13,000 years. It takes about 25,776 years to complete one precessional cycle.
