Definition
Otto Neugebauer and Henry B. Van Hoesen, Greek Horoscopes is an astrological source represented here through cited material on dating, history, Hellenistic astrology, aspects, and astronomical method.

What this work covers
The cited material covers dating, history, Hellenistic astrology, aspects, and astronomical method.
Neugebauer and Van Hoesen define katarchic astrology as judging how the celestial configuration at an undertaking's beginning bears on that undertaking's outcome, distinguishing its event-specific scope from a nativity's life-wide scope.
The work describes historical loci as a separate twelvefold ecliptic division whose places may be counted from the Horoscopos or, for specialized topics, from the Lot of Fortune; it also cautions that detailed topical assignments vary across sources.
Chapter IV attributes literary horoscope layers by comparing manuscript versions, internal dates, astronomical positions, stellar precession, citations, parallel passages, and historical references for Valens, Critodemus, Antigonus, Hephaestion, Palchus, Rhetorius, Eutocius, and Stephanus, often retaining uncertainty.
