Via Combusta

VEE-ah kom-BUS-tah

Definition

The via combusta — the "burned way" or "burning road" — is a stretch of the zodiac usually marked off as 15 degrees Libra to 15 degrees Scorpio. In horary astrology, which answers a question from a chart cast for the moment it was asked, the Moon falling in this stretch acts as a warning sign before the astrologer judges the chart: it suggests the matter is unstable, unsafe, or simply not ready to be judged. The exact boundaries vary by author — some draw the stretch instead from a list of difficult fixed-star degrees rather than a clean 30-degree band.

In Tradition

Traditional and horary astrologers read the via combusta as a troubled zodiac stretch. A planet there — above all the Moon, a horary chart's chief timekeeper — is a cue for caution. They disagree on the exact boundaries and how strictly it applies: some confine the warning to the Moon, others extend it to any significator (the planet standing in for a person or matter) in the zone. Modern practitioners may call it a relic; traditional revival writers keep it.

In Practice

A horary astrologer checks the Moon's degree at the moment the question was asked. If the Moon lands between roughly 15 degrees Libra and 15 degrees Scorpio, the chart is flagged as carrying a warning before judgment, and the astrologer either declines the question, asks for it to be put again, or answers with explicit caution. Some authors widen the rule to flag any significator caught in the zone, not just the Moon, and some draw the boundary from a list of difficult fixed stars — notably including certain Royal Stars — rather than a continuous 30-degree band. Modern Western practice varies: some treat the rule as binding, others as advisory.

Historical Origin

The via combusta doctrine appears in the medieval Arabic-Latin tradition — Bonatti treats it among the rules of cosmic state and election — and was set down for the English horary tradition by William Lilly in Christian Astrology (1647). The rule survives in modern traditional revival sources including Lehman and Louis. Some authors trace its troubled reputation to the fall of the two lights within the arc: the Sun is in fall in Libra, the Moon in fall in Scorpio.

Etymology
