WHAT IT IS

Each letter of the Greek alphabet has a numerical value. The full Milesian system uses 27 symbols — the 24 letters of the classical alphabet plus three archaic ones: Digamma Ϝ=6, Qoppa Ϙ=90 and Sampi Ϡ=900. The lexarithmos of a word is the sum of its letter values. Two words with the same lexarithmos are called isopsephic — and this mathematical relation reveals deeper connections between concepts: words sharing the same number belong to the same semantic field.

HISTORY & SOURCES

The Milesian numeral system appeared in the 6th–5th cent. BC. The three archaic letters (Ϝ, Ϙ, Ϡ) fell out of everyday writing but were retained as numerical symbols. Isopsephy as an analytical method appears in the Sibylline Oracles, among the Gnostics, in Patristic texts and in early Christian letters. Marcus the Gnostic (2nd cent.) used it extensively. The search for isopsephic words is not "divination" — it is mathematical analysis of language: we seek which concepts share the same number, and this relation gives deeper meaning to each word. The most famous isopsephies: JESUS = 888 and 666, the number of the beast in the Revelation of John.

Origin and typology: According to Chrisomalis (2010), the Milesian system descends from Egyptian demotic numerals — Ionian merchants in Naucratis (Nile delta, 6th cent. BC) borrowed the structure, replacing symbols with Greek letters. Typologically it belongs to the "ciphered-additive" type — of the 5 types of numerical notation catalogued by Chrisomalis, this is the only one that enables isopsephy, because each letter has a fixed numerical value regardless of position. From the Greek model arose 10 descendant alphabetic systems: Hebrew (~125 BC), Gothic (~350 AD), Coptic, Ethiopic, Armenian, Georgian, Syriac, Arabic abjad, Cyrillic and Latin alphabetic. In 5,500 years of world history, only 6–7 numerical systems were invented independently — the remaining ~93 are borrowed or modified.

HOW IT WORKS

Word: ΛΟΓΟΣ
Λ=30, Ο=70, Γ=3, Ο=70, Σ=200
30 + 70 + 3 + 70 + 200 = 373
Lexarithmos of ΛΟΓΟΣ = 373
Search for isopsephic words: which words in the database also have lexarithmos 373?
Find isopsephic pairs: which two words sum to 373?
Result: each isopsephic word reveals a mathematical connection of meanings.

CONCLUSION

Isopsephy is the fundamental method: we calculate the lexarithmos and search for isopsephic words. Two words with the same lexarithmos share numerical identity — this relation is not accidental but inherent in the structure of the language.
