Horary Astrology
HOR-air-ee uh-STROL-uh-jee
greek: Καταρχή (Katarchē) · latin: interrogationes
Definition
Horary astrology answers a specific question by casting and interpreting a chart for the moment the question is asked. The name comes from Latin hora ("hour") — the chart is built for the hour of the inquiry, and the astrologer reads the chart for the answer. The Greek conceptual antecedent is katarchē ("inception, beginning"), and Holden identifies Dorotheus' Book V as the oldest surviving treatise on horary and electional astrology, with Dorotheus' theft-rules as the most extensive early material. Benjamin Dykes notes that "horary astrology" is itself a relatively modern English convention — the traditional designation in both Hellenistic and medieval texts is "Questions" (Greek erōtēseis; Arabic masāʾil; Latin interrogationes). Hephaistio devotes Book III to the inquiries of those wishing to investigate a matter, and the chapter opens explicitly at III.4.
In Tradition
In the traditional schools, horary is read as the most divinatory of the branches of astrology. Avelar and Ribeiro frame it sharply: it gives answers to specific questions by interpreting the chart cast for the moment the question was formulated. The pivotal importance of the question's hour gives the branch its name. Hellenistic katarchic doctrine — Dorotheus' Book V — is the foundation; the Arabic-medieval expansion in the Iberian peninsula and the broader Persian and Arabic synthesis develop the technique into the form Lilly preserves in Christian Astrology (1647). The standard horary reading takes the Ascendant as the querent, the seventh house as the other party in a contest or relationship, the lord of the matter (the planet ruling the relevant house) as the thing asked about, and the Moon as the universal co-significator.
In Practice
When you formulate a horary question, the astrologer records the exact hour and place the question was put — that moment's chart is what gets read. The classical procedure: read the Ascendant and its lord for the querent (you, asking the question); the house ruling the topic (with its lord) for the thing inquired about; the seventh and its lord for any other party; the Moon for the matter's flow and immediate context. Watch the considerations before judgment that Lilly codifies — chart features that warn the judgment may be unreliable (Moon void of course, Saturn in the first or seventh, very early or very late Ascendant degrees, and others). Decumbiture (the sickbed chart) and inception (a chart cast for the start of an enterprise) are sibling katarchic techniques, sharing horary's logic of reading the chart of a moment. Modern traditional horary — Frawley, Louis, and others — works from Lilly's seventeenth-century apparatus, while modern Hellenistic-revival practitioners (Brennan, George) trace the doctrine back through the Arabic-medieval synthesis to Dorotheus' Greek-language origin.
Historical Origin
Horary astrology is canonical Hellenistic-through-Arabic-through-Renaissance doctrine. Dorotheus' Book V (1st century CE) is the oldest treatise on horary and electional astrology that has come down to us, transmitted through Persian and Arabic sources to become the foundation of the medieval Arabic horary tradition. Hephaistio III.4 explicitly opens the questions / horary section of the Apotelesmatica. Dykes' terminology-note in his Cazimi edition flags that "horary astrology" is a late-historical English designation for the traditional category called "Questions" (erōtēseis / masāʾil / interrogationes). Avelar and Ribeiro identify horary as the Arabic-medieval expansion of Greek doctrine — Arabic astrologers provided continuity with Greek astrology, deepening its mathematical precision and expanding the branch notably. The doctrine is preserved through Bonatti and Lilly into the modern Western revival.
