Illuminati gematria refers to a system of numerology and cryptography allegedly used by the Bavarian Illuminati, a secret society founded in 18th-century Germany. The term "gematria" originates from the Greek word γηματρια, meaning "geometric" or "figurative," and is often associated with Jewish numerology, where Hebrew letters are assigned numerical values for interpretive purposes. In the context of the Illuminati, gematria is said to have been employed to encode and decode messages, assign significance to numbers, and create ciphers for secret communications. The practice is sometimes linked to the broader esoteric traditions of the Enlightenment era, where secret societies often utilized complex symbolic systems. The Hebrew translation for "gematria" is גימטריה, while in German, it is known as Gematria or Buchstabenwertlehre (literally "doctrine of letter values"). The concept has been popularized in modern conspiracy theories, often without historical evidence, suggesting that the Illuminati and other secret societies continue to use such methods for hidden agendas.
