Greek isopsephy is a form of gematria, the practice of assigning numerical values to words or phrases based on the sum of the values of their letters. In Greek isopsephy, each letter of the Greek alphabet is assigned a numerical value, typically corresponding to its position in the alphabet (e.g., α = 1, β = 2, γ = 3, etc.). This practice was used in ancient Greece for various purposes, including divination, cryptography, and the interpretation of religious texts. The term "isopsephy" is derived from the Greek words isos (ἴσος), meaning "equal," and psēphos (ψῆφος), meaning "pebble" or "vote," reflecting the historical use of pebbles for counting and voting. In Hebrew, this concept is known as gimatria (גימטריה), and similar practices exist in other cultures, such as the Hebrew gematria and the Arabic abjad numerology. Greek isopsephy was particularly significant in the study of the New Testament and other early Christian texts, where it was used to uncover hidden meanings and connections between words and numbers.
