Isopsephia Calculator

The 24 letters of the Greek alphabet each represent both a sound and a number. They are arranged in three groups of eight: units (1-9), tens (10-90), and hundreds (100-900). Three archaic letters (Stigma, Qoppa, Sampi) fill the gaps at 6, 90, and 900.

This system was invented almost a thousand years before the birth of Jesus. Every literate Greek person knew it. It meant that every word, name, and phrase in the Greek language had a calculable numeric value.

Isopsephia (from iso “equal” + psephos “pebble”) is the practice of adding the letter values of a word to produce a single number. This was widespread in the Greco-Roman world.

A famous example: the Christian Sibylline Oracle (c. 150 AD) describes the son of God as having “four vowels, twofold consonants” and a name totaling “eight monads, eight decads, and eight hundreds” (8 + 80 + 800 = 888). Only the Greek name ΙΗΣΟΥΣ (Jesus) fits all constraints.

Gematria (from Greek geometria) goes beyond isopsephia by mapping numeric values onto geometric objects. A word’s value becomes the circumference of a circle, the side of a square, or the length of a line.

The name “Jesus” (888), when “raised” by a factor of 10 to 8880, becomes the circumference of the master circle on which all gospel diagrams are constructed.

This calculator uses the standard 27-character Greek alphanumeric system. It handles Unicode Greek text (including polytonic/accented characters), archaic numerals, and Latin transliteration. All values can be independently verified using any Greek alphabet reference.
