History & development
The Hamburg School grew around Alfred Witte's methods, with Friedrich Sieggrün and Ludwig Rudolph involved in its organization and publishing. Witte-Verlag traces a connected publication to 1925 and the English name 'Uranian' to the following decade. The term names a methodological tradition, not just one organization.
Mythology & symbolic world
Planetary pictures combine symbolic factors in equations. Eight additional factors bear names such as Cupido, Hades and Poseidon, but these are hypothetical bodies. Their mythological names and reproducible model positions should not be confused with discovery of physical planets.
Provenance: where the rules come from
Specify the dial, midpoint conventions, planetary-picture rulebook and hypothetical-body orbital model. Swiss Ephemeris identifies its Hamburg factors as unobserved and uses revised model elements.
How it is calculated
Choices that change the result: Planetary-picture rulebooks and comprehensive midpoint trees not implemented.
Inspect your calculated data →Uses & use cases
- Explore symmetrical angular patterns and compare dial representations.
- Study Hamburg School publications within their German and international history.
Interpretation methods
Planetary-picture reading
Identify a relationship such as A/B = C, state its tolerance and dial equivalences, then apply an attributed rulebook entry.
Two points at 20° and 60° have a midpoint at 40°. A third point there supplies a geometric picture before any meaning is assigned.
Concepts in this tradition
Follow a term for its definition, word origin, evidence and connected ideas.
Disagreements & limits
- Calculating eight hypothetical factors does not implement the full school.
- Dial equivalence can hide whether a relationship was a conjunction, square or opposition in the original wheel.
Sources & evidence
Practitioner sources describe their own systems. Historical and astronomical sources support different kinds of claims. Reading exercises are editorial teaching examples.
