Hellenistic Astrology
Dated Greek and Roman horoscopic authors, texts, and methods. This guide gives a reproducible rule, worked example, illustrative near miss, and explicit limits.
Overview
Hellenistic astrology names diverse Greek- and Roman-era horoscopic practices whose surviving authors disagree on techniques, terminology, and philosophical framing. The page separates calculation from interpretation and keeps this worked result conditional: sect is diurnal and the day triplicity column is used; the method is attributed to a dated source family. Verification follows this declared method: Identify the author, work, book, chapter, manuscript or edition, translation, and date before attributing sect, lots, profections, or house meanings.

Calculation or decision rule
identify the author, work, book, chapter, manuscript or edition, translation, and date before attributing sect, lots, profections, or house meanings
Worked case and illustrative near miss
chart has ☉ above the horizon; whole-sign houses selected; Dorothean triplicity rulers declared. sect is diurnal and the day triplicity column is used; the method is attributed to a dated source family.
Illustrative near miss: Labeling any whole-sign chart “Hellenistic” while importing later techniques without disclosure.
School and variant boundary
The label covers dated authors and lineages; no one source may be silently promoted to a universal astrology rule.
Product, safety, and verification boundary
OpenFate can expose the chart inputs needed for Hellenistic Astrology, but it does not claim a dedicated automated interpretation for this technique. Verification retains failed measurements and uncertainty, then revises interpretation rather than the receipt. Hellenistic Astrology cannot diagnose a person, remove consent, or guarantee an event.
