Stoicheia
Planets, zodiac and elements per the papyri
WHAT IT IS
Each letter corresponds to a planet, zodiac sign, or element (earth, water, air, fire, ether). There are two systems: PGM (from the Greek Magical Papyri) and the Barry system.
HISTORY & SOURCES
The idea that the 7 vowels correspond to the 7 planets is based on the Pythagorean harmony of the spheres. Nicomachus of Gerasa (~60–120 AD) in his Manual of Harmonics is the oldest surviving source that explicitly corresponds the 7 vowels (Α Ε Η Ι Ο Υ Ω) to the 7 planetary sounds.
The Papyri Graecae Magicae (2nd cent. BC–5th cent. CE) extend the system: 7 vowels → planets, 5 compound consonants (Θ Ξ Φ Χ Ψ) → 5 elements, 12 remaining consonants → 12 zodiac signs. Thus the entire alphabet (24 letters) corresponds to the cosmos. The vocal chanting of vowels was used in magical invocations to "activate" planetary forces. Barry (1999) presents a variant based on the initials of Greek element names.
CORRESPONDENCES (PGM)
| Α | 🌙 Moon |
| Ε | ☿ Mercury |
| Η | ♀ Venus |
| Ι | ☉ Sun |
| Ο | ♂ Mars |
| Υ | ♃ Jupiter |
| Ω | ♄ Saturn |
| Θ,Ξ,Φ,Χ,Ψ | Elements (PGM) |

HOW IT WORKS
- Word: ΛΟΓΟΣ
- Λ → ♍ Virgo (zodiac)
- Ο → ♂ Mars (planet)
- Γ → ♉ Taurus (zodiac)
- Ο → ♂ Mars (planet)
- Σ → ♒ Aquarius (zodiac)
CONCLUSION
The astrological analysis shows which cosmic forces "compose" the word. Words with a dominant Sun planet were considered "solar" etc.
