Horary Astrology

Horary astrology is a branch of Western astrology specializing in answering specific questions.

Chart of the question, not the birth. Unlike natal astrology, which works with the birth chart, horary casts a chart for the moment the astrologer receives and understands the client's question.

"The birth of the question". This moment is treated as the "birth of the question" — the point at which the situation has crystallized sufficiently for symbolic analysis.

History and Formalization

Lilly, 1647. The method was formalized in the seventeenth century by William Lilly in his treatise "Christian Astrology" (1647).

Roots. Extend to Arab astrologers of the 8th–12th centuries (Masha'allah, Abu Ma'shar) and further back to the Hellenistic tradition.

Revival in the 20th century. Among modern continuators are Olivia Barclay, who revived the method in Britain in the 1980s, and John Frawley.

The Technical Language

The same as natal. Horary employs the same language as natal astrology — signs, planets, houses, aspects — but interprets them differently.

Significators

• The querent (the person asking) — represented by the ruler of the 1st house
• The quesited (the subject of the question) — represented by the ruler of the relevant house:
  • 7th — for a partner
  • 10th — for career
  • 4th — for property

The Logic of the Answer

The answer is determined by aspects between significators:

• Application (approaching aspect) → "yes"
• Separation → "no"
• Prohibition or translation of light → the intervention of third forces

Place in Errarium

The event-oriented branch. In Errarium, horary astrology (#56) represents the event-oriented branch of Western astrology.

Analog — Prashna. Its closest analogue is Prashna (#58), the Vedic equivalent using the sidereal zodiac and nakshatras.

Difference from natal. The fundamental difference from natal astrology (#1) is the focus on the moment of the question rather than the moment of birth, making the method more agile and narrowly targeted.
