WHAT IT IS

Each letter has its own symbolism — origin from Egyptian hieroglyphs, astrological correspondences, philosophical meanings and connections to deities or concepts. This symbolism constitutes a "dictionary" of archetypes.

HISTORY & SOURCES

There is no single inventor — the individual symbolism of letters evolved in multiple layers:

Plato (Cratylus, ~360 BC): the oldest philosophical treatment. Plato analyzes how individual letters "imitate" movements and properties — e.g. rho (ρ) = movement, lambda (λ) = smooth motion, sigma/xi = roughness.

Marcus the Gnostic (2nd cent. CE): the most complete ancient system of individual grammatical symbolism — each letter corresponds to a cosmic archetype and a member of the Body of Truth.

Iamblichus (On the Mysteries, ~300 AD) and Proclus (5th cent.): in Neoplatonic theurgy, letters and divine names possess inherent sacred power (synthemata/symbola). Iamblichus treats each letter as a carrier of divine energy.

Byzantine source "On the Mystery of Letters" (6th cent. CE): the closest surviving systematic treatise on individual Greek letter symbolism.

HOW IT WORKS

Each letter of ΛΟΓΟΣ has its own symbol:
Λ → Golden Ratio (Timaeus Sequence)
Ο → Eye · Mars
Γ → Triad · Fates
Σ → Aquarius

CONCLUSION

Individual letter symbolism gives a "poetic" interpretation of each letter. The chain of symbols of a word forms an "image" of its meaning.
