About Traditional Astrology
The story behind the engine — and why it exists.
How This Started
I'm not an astrologer. I'm a systems architect.
A few years ago I started reading Vettius Valens, Guido Bonatti, William Lilly — the old sources that most modern astrologers skip. What I found was a rigorous, rule-based system buried under 2,000 years of telephone. Clear if-then logic. Testable claims. Repeatable methods.
So I did what I do for a living: I broke the system down into components, verified each rule against the source texts, and built software to enforce them. Sect, dignities, almuten, mutual receptions, profections — all computed from ephemeris data, no hand-waving.
I didn't invent any of this. I just made the old rules run on modern hardware.
What We're Doing
Most astrology software gives you planet positions and a paragraph of vibes. We wanted something different: readings you can actually check. Every interpretation traces back to a named source, runs through documented rules, and tells you when it doesn't have enough data to make a call.
Where the Rules Come From
These aren't techniques we invented. They're drawn from three major periods of astrological writing.
Hellenistic (2nd–5th c.)
Ptolemy, Dorotheus, Valens, Firmicus. They established sect, essential dignity, and the house system we use. This is where most of the engine's core logic originates.
Medieval Arabic (8th–13th c.)
Abu Ma'shar, Al-Biruni, Bonatti. They preserved the Greek material, tightened the judgment rules, and added timing techniques like firdaria.
Renaissance (16th–17th c.)
William Lilly and his contemporaries. They wrote the practical manuals — how to weigh planetary strength, when a testimony is strong enough to call, when it isn't.
What We Don't Do
Honesty about limits matters more than covering every angle.
Not therapy
This is a calculation engine, not a counselor. We don't do "healing journeys" or tell you what your Saturn return means for your inner child.
Not medical or legal advice
Some classical texts mention health correspondences. We include them as historical context, clearly labeled. Don't make health decisions based on a birth chart.
Not guessing
If your birth time is missing, we say so and skip the techniques that need it. We'd rather leave a section blank than make something up.
How to Check Our Work
Every reading comes with the receipts.
Show the math
Your report includes the raw calculation data — planet positions, dignity scores, aspect tables. You can verify any claim against the numbers.
Name the source
When we say "Valens says X" or "Bonatti's rule for Y," we mean it. The methodology page lists exactly which texts inform each technique.
Admit the gaps
If a technique can't be applied — missing birth time, ambiguous data — the report says so instead of filling the space with vague language.
