Invention of Numerology

There are numerous popular numerology methods. The one practiced at this website is Pythagorean numerology.

It's named that because the ancient Greek philosopher and mathematician Pythagoras is considered to be the father of the practice.

The practice evolved over 2500 years to be what it is today.

Numerology's evolvement generally was according to observation. Things were observed to be true and calculations developed for it. If they weren't accepted by the most influential numerologists at the time the new calculations are unlikely to have been integrated into the practice.
