Midpoints and planetary pictures
Midpoints, the formulas A = B/C and A + B = C + D, orbs, and the midpoint tree, the core of a Uranian reading.
The midpoint
The midpoint of two factors B and C, written B/C, is the point halfway between them: (B + C) / 2. There are always two, exactly opposite each other. In Uranian astrology both count, because a midpoint is read through every hard angle.
A = B/C
When a third factor A stands on the midpoint B/C, or 45°, 90°, 135° or 180° from it, the three form a planetary picture: A = B/C.
The picture is read as a sentence. The meanings of B and C combine, and A says where or through what the combination shows. For example:
- Sun = Venus/Jupiter joins the body and vitality (Sun) to pleasure and good fortune (Venus, Jupiter).
- MC = Saturn/Hades joins the self (MC) to restriction (Saturn) and to what is old or hidden (Hades).
Pictures on the six personal points weigh most.
A + B = C + D
Two midpoints can also coincide: A/B = C/D. The same relationship can be written A + B = C + D, or, solved for one factor, A + B − C = D.
These sum pictures link four factors at once. They show that what A and B produce together is also what C and D produce.
Orbs
Pictures are taken only when they are close. Hora Horoscope uses an orb of 1° for midpoints and sum pictures. It lists each picture with its orb, tightest first, so the strongest come first.
Aspects from the personal points are shown up to 4°.
The midpoint tree
The midpoint tree lists, for each factor, every midpoint that falls on it. It is the raw material of a reading: each line is a picture. The chart page shows the full tree for the 22 factors.
