Aries, Leo and Sagittarius are southern wind trigon of Sun by day and Jupiter by night
Taurus, Virgo and Capricorn are western wind trigon of Venus by day and Moon by night
Gemini, Libra and Aquarius are northern wind trigon of Saturn by day and Mercury by night
Cancer, Scorpio and Pisces are eastern wind trigon of Mars
Because winds always predominate an exact direction, and because there are four possible general directions of winds, the twelve places are sharply pointed in groups of three separated by four places, that is by the figure of the trigon.
Aries + Leo + Sagittarius = 1 Moisture + 1/2 Heat + 1 Heat + 1/2 Dryness + 1 Dryness + 1/2 Cold = 1 Heat + 1/2 Dryness (South or Fire)
Taurus + Virgo + Capricorn = 1 Moisture + 1/2 Heat + 1 Heat + 1/2 Dryness + 1 Cold + 1/2 Moisture = 1 Moisture + 1/2 Heat (West or Air)
Gemini + Libra + Aquarius = 1 Moisture + 1/2 Heat + 1 Dryness + 1/2 Cold + 1 Cold + 1/2 Moisture = 1 Cold + 1/2 Moisture (North or Water)
Cancer + Scorpio + Pisces = 1 Heat + 1/2 Dryness + 1 Dryness + 1/2 Cold + 1 Cold + 1/2 Moisture = 1 Dryness + 1/2 Cold (East or Earth)
Thus, Aries, Leo and Sagittarius are southern wind trigon of Sun by day and Jupiter by night, more moistening by night due to the moisture of the night.
Taurus, Virgo and Capricorn are western wind trigon of Venus by day and Moon by night, more cooling by night due to the cold of the night.
Gemini, Libra and Aquarius are northern wind trigon of Saturn by day and Mercury by night, more moistening by night due to the moisture of the night, this wind is predominated by Mercury by night to account for the moderate moisture, occasional fecundity and beneficence, note that half of the time by night, this wind becomes feminine and nocturnal.
Cancer, Scorpio and Pisces are eastern wind trigon of Mars both by day and by night, as only Mars produces such drying and maleficent winds. To account for the moderate cold of the winds, some of the old astrologers put Venus as cooperating lord by day, and Moon as cooperating lord by night, however this does not seem right to me, as they are moistening planets.
The winds seem point at the seasonal powers of the solid places.
Of course, for the Southern Hemisphere, the equatorial winds of Sun and Jupiter become northern, and the polar winds of Saturn and Mercury become southern, as the direction of their two angles are reversed, likewise this differentiation of winds applies only to the general winds within the fronts, and not to every single locality at all times...
Likewise, for universal and genethlialogical investigations exactly at the equator, different system of predomination is to be used, based on complete and powerful configurations having twice the power of operative and moderate configurations, and predomination based on the qualities of angles (Hour-Marker - Mars, Midheaven - Sun by day and Jupiter by night, Setting - Venus by day and Moon by night, Anti-Midheaven - Saturn by day and Mercury by night) because the predominations of houses, elevations, trigons and bounds are useless. Planets become powerful, operative and inoperative only based on their angularity and phases in case of the five planets. For investigations in between the equator and the tropics, both equatorial and temperate systems are to be used proportionally.
