Practice, Not Verdict

The atlas describes these disciplines as historical and cultural systems, what practitioners have believed and done, without ruling on whether their claims are true. Astrology, alchemy and divination have long and serious histories, deeply entwined with the development of astronomy, chemistry and philosophy, and are treated with that history in view rather than as mere superstition or as established fact.

Because a discipline organises many of the other categories here: astrology gathers the planets, signs and houses, and alchemy the operations and stages. A discipline entry serves as a doorway into a whole cluster of related pages.
