Western Astrology

Western horary chart facts

The chart of a question's moment with the facts Lilly's horary method reads, each rule named. House rulers (traditional rulers), the significators (lord of the 1st and the Moon for the querent, lord of the quesited house), their aspects with Lilly's orbs and whether an applying aspect perfects before a sign change, the Moon's last and next aspects and void-of-course state, combustion, and the considerations before judgement (radicality by the hour lord, early or late Ascendant, Saturn in the 7th, the Moon in the Via Combusta). The yes or no is left to the reader. Christian Astrology (1647).
