Eight Rules from Guido Bonatus for Judging Horary Questions
Guido Bonatus sets out eight considerations (62–69) that can influence the outcome of a horary question, covering the Moon’s condition, aspects from benefics and malefics, eclipses, the seventh house in illness charts, and procedures when significators are equally strong. These rules illustrate how medieval astrologers applied detailed criteria to assess the likely success or failure of a matter.
