What is an ancient form of numerology?

An ancient form of numerology is the practice associated with the Pythagorean system, developed by the Greek philosopher Pythagoras in the 6th century BCE. This system assigns numerical values to letters in the alphabet, allowing practitioners to analyze names, Words, and dates to uncover hidden meanings and insights about personality and destiny. Another notable ancient form is the Chaldean numerology from Babylon, which is based on a different letter-number correspondence and emphasizes the vibrational qualities of numbers. Both systems have influenced various mystical and philosophical traditions throughout history.
