The Language of Uranian Astrology by Roger A. Jacobson (1975) is a foundational text detailing the Hamburg School of Astrology created by Alfred Witte. It emphasizes a precise, mathematical approach using 90-degree dials, midpoints, planetary pictures, solar arcs, and eight hypothetical trans-Neptunian planets (TNPs) to interpret horoscopes.
Key concepts covered in The Language of Uranian Astrology include:
Planetary Pictures & Midpoints: The core of the system focuses on "pictures"—formulas where two planets (
) equal a third (
) or a midpoint—to interpret specific events and personality traits.
Trans-Neptunian Planets (TNPs): The system uses8 hypothetical planets: Cupido, Hades, Zeus, Kronos, Apollon, Admetos, Vulcanos, and Poseidon.
90-Degree Dial: Instead of the 360-degree wheel, Uranian astrology often uses a 90-degree dial to easily identify hard aspects (conjunctions, squares, oppositions).
Key Elements: The text covers the 360-degree dial, Uranian houses, meridian (MC), Ascendant (ASC), Sun, and Moon, as well as zodiacal physiology.
Focus: It emphasizes practical application, using Rules for Planetary Pictures for interpretation rather than relying solely on traditional house/sign analysis
