Greek Isopsephy Calculator
Enter a Greek word, phrase, or sentence. The calculator normalizes accents and computes the total using traditional Greek letter values.
What Is Isopsephy?
Isopsephy is an ancient Greek practice in which each letter carries a numeric value. By adding the values of letters in a word or phrase, you get a total that can be compared with other words or interpreted symbolically. It is related to, but distinct from, Hebrew gematria. In classical and late antique literature, this method was sometimes used in puzzles, inscriptions, and rhetorical play.
How This Calculator Works
This page uses the traditional Greek alphanumeric mapping:
- Units: α=1, β=2, γ=3, δ=4, ε=5, ϛ/ϝ=6, ζ=7, η=8, θ=9
- Tens: ι=10, κ=20, λ=30, μ=40, ν=50, ξ=60, ο=70, π=80, ϟ=90
- Hundreds: ρ=100, σ=200, τ=300, υ=400, φ=500, χ=600, ψ=700, ω=800, ϡ=900
To make results practical for modern text input, the calculator performs a few normalization steps:
- Converts letters to lowercase
- Removes Greek diacritics (accents and breathing marks)
- Treats final sigma ς as sigma σ
- Ignores spaces, punctuation, and non-Greek characters
Example Calculation
Word: ἸΧΘΥΣ
After normalization, the letters are ι χ θ υ σ.
- ι = 10
- χ = 600
- θ = 9
- υ = 400
- σ = 200
Total: 1219
Use Cases
An isopsephy tool is useful for:
- Studying ancient Greek inscriptions and textual traditions
- Comparing numeric patterns across names, titles, or short phrases
- Classroom demonstrations in history, classics, theology, and linguistics
- Personal curiosity when exploring symbolic number systems
Important Notes on Interpretation
Isopsephy can be historically interesting, but totals alone do not prove a hidden meaning. Different manuscripts, spelling variants, orthographic traditions, and editorial decisions can change results. Treat the output as a research aid and not as definitive evidence by itself.
Tips for Better Results
- Use authentic Greek spelling whenever possible.
- Compare multiple spellings if your source text has variants.
- Record normalization choices (e.g., whether diacritics were removed).
- Keep your work transparent so other readers can reproduce your totals.
Quick FAQ
Does this work with accented Greek?
Yes. Accents and breathing marks are removed before calculation.
What happens to punctuation and numbers?
They are ignored and not included in the sum.
Can I use this for non-Greek text?
You can paste anything, but only recognized Greek letters contribute to the final value.
