    Guido Bonatti’s 125th and 126th Considerations: Ascendant Sign and the Power of Mercury

    This exposition of Bonatti’s 125th and 126th considerations shows how the rising sign in a nativity or horary question ties the Ascendant to the affairs of another house ruled by the same planet, and how Mercury’s condition and placement—especially in Capricorn or Aquarius—shape character and intellect. These ideas illustrate the medieval astrological focus on planetary rulerships and practical judgment.

    Guido Bonatus on Planetary Conditions: Considerations 26–40

    The following considerations, numbered 26 through 40, detail how the medieval astrologer Guido Bonatus assessed planetary strength and weakness—including speed, station, aspect, and dignity—to judge the likely outcome of a matter. The focus is on the nuanced ways difficult planets (infortunes) might either hinder or assist depending on their placement and connections. These guidelines reflect a historical approach in which astrology was applied as a practical set of rules, with careful attention to planetary behavior and context.

These rules illustrate how medieval astrologers applied detailed criteria to assess the likely success or failure of a matter.
