Hellenistic & Medieval Astrological Traditions

From the Lesson

Modern astrology inherits from two great streams: the Hellenistic synthesis that created horoscopic astrology, and the Medieval Arabic developments that refined its techniques.

HELLENISTIC ASTROLOGY (1st Century BCE - 7th Century CE):

WHOLE SIGN HOUSES: The original system where each sign equals one house. If Aries rises, all of Aries is the 1st house.

SECT: Division of planets into Day and Night teams. In a day chart, Sun, Jupiter, and Saturn operate with enhanced beneficence. In a night chart, Moon, Venus, and Mars are favored.

LOTS (Arabic Parts): Calculated points derived from distances between planets. The Lot of Fortune (Ascendant + Moon - Sun) reveals luck; the Lot of Spirit reveals purpose.

TIME-LORD SYSTEMS: Annual Profections (advancing one sign per year), Zodiacal Releasing, and Primary Directions for precise timing.

MEDIEVAL ARABIC ASTROLOGY (8th - 15th Century CE):

ALMUTENS: Calculation of the single strongest planet over a point or topic.

FIRDARIA: Persian time-lord system assigning planetary periods of varying lengths in specific sequences.

PROFECTIONS: Each birthday, the chart 'profects' one sign forward, activating planets in and ruling that sign for the coming year.

SOLAR RETURNS: The return of Sun to its natal position provides a chart for the coming year.

HORARY ASTROLOGY: Casting a chart for the moment a question is asked to determine the answer.

THE PLANETARY HOURS: Each hour ruled by a planet in Chaldean order, coloring activities undertaken during that time.

These classical techniques fell out of favor but have experienced a renaissance since the 1990s, with contemporary astrologers integrating traditional techniques with psychological insight.
