Astrology, written down plainly
Notes on the symbols, the history, and the arguments — without the breathless bit.
Astrology is one of the oldest continuously practised symbolic systems in the world. It shaped the vocabulary of medicine, agriculture and politics for centuries, and it is still, by a wide margin, the most widely recognised symbolic language most people encounter.
Whether or not you think it tells you anything about the future, it is worth understanding what it actually says. These pages set out the structure without assuming you already believe it.
The signs
Twelve divisions of the ecliptic, their traditional attributes, and how those attributes were arrived at.
The planets
The classical seven, the modern additions, and what each was taken to signify before and after the telescope.
Houses and aspects
The geometry underneath a chart — why the same sky means different things at different places and hours.
History
Babylon, Hellenistic Egypt, the medieval Islamic world, the European Renaissance, and the twentieth-century revival.
What astrology claims, and what it does not
Traditional astrology is a symbolic craft, not an experimental science, and its better practitioners have generally said so. It offers a vocabulary for describing temperament, timing and situation — not a mechanism, and not a prediction that can be checked the way a weather forecast can.
Controlled studies have consistently failed to find the effects that popular astrology implies. That is worth stating clearly, and it does not make the symbolic system less interesting to study or less historically important.
How to read these notes
Descriptively. Where we set out what a tradition holds, we are reporting the tradition, not endorsing a claim about how the world works. Where we think something is overstated, we say so.
Nothing here is advice — medical, financial, legal or personal. If you are facing a decision that matters, talk to someone qualified in the actual subject.
