Who invented Chaldean numerology?

Numerology, the study of the mystical relationship between numbers and events, has captivated human curiosity for centuries. While many different numerology systems exist, one of the oldest and most influential is the Chaldean system. In this post, we will explore the origins and evolution of Chaldean numerology over the centuries. From its beginnings in ancient Mesopotamia to its modern applications, the story of this numerology system is filled with fascinating details. Read on to learn all about the rich history of Chaldean numerology!

The Birth of Chaldean Numerology in Ancient Babylon

The origins of Chaldean numerology can be traced back approximately 2,500 years to ancient Mesopotamia, specifically the region of Babylonia. The Babylonians were renowned mathematicians, astronomers and diviners who believed that numbers held mystical powers. They developed sophisticated systems to record dates, predict celestial events, and determine the will of the gods.

Within this advanced culture, the earliest roots of Chaldean numerology began to grow. The Chaldeans analyzed the hidden meanings behind names and dates, assigning numeric values to letters and interpreting them for insights. For example, they believed certain numbers like seven were spiritually significant. Over centuries, the Chaldeans refined their techniques into an elaborate numerology system. While the original Chaldean civilization collapsed in 539 BCE, their numerological teachings endured.

Spreading to the Ancient Greeks and Beyond

In later centuries, Chaldean numerological ideas spread beyond Mesopotamia into the Mediterranean. Aspects of the system were adopted by ancient Greek philosophers like Pythagoras who also studied the metaphysical meanings of numbers. The Greeks helped expand Chaldean numerology across Europe. Later, in the 8th century, it was likely introduced to the Arabic world where it flourished alongside other numerological traditions.

By the Middle Ages, Chaldean numerology had blended with various mystical schools of thought including Jewish Kabbalah and Christian Gnosticism. Occultists continued practicing it over the centuries. Throughout this evolution, the name “Chaldean” stuck, immortalizing the original Mesopotamian innovators even as their system transformed. While modified over thousands of years, the basic premise of decoding symbolic numbers persisted as Chaldean numerology’s cornerstone.

Resurgence in the Modern Era

Interest in Chaldean numerology surged again during the 19th and 20th centuries alongside wider fascination with the supernatural. In 1898, a Chaldean scholar named Sepharial (a pseudonym for Walter Gorn Old) published influential books on the subject. He promoted Chaldean methods derived from ancient texts and his own research.

Many modern numerologists claim to use original Chaldean systems passed down from antiquity. Whether truly ancient or modern reinterpretations, these Chaldean techniques remain popular today. They involve calculating numeric values for names and mapping out “destiny numbers” on the Chaldean numerology chart said to reveal life insights. Despite lacking scientific validity, the appeal of unlocking one’s future proves eternally alluring!


From the mathematicians of Mesopotamia who pioneered numeric divination to the occultists of today who embrace the Chaldean label, this numerology system has unexpectedly endured across millennia. The original Chaldean civilization may have vanished, but its mystical numeric philosophy continues to enthrall spiritual seekers and mathematicians alike. For those fascinated by the idea of numbers as codes to life’s mysteries, Chaldean numerology’s winding history remains an intriguing adventure to follow.
