The 90° dial
How the Uranian 90° dial folds the zodiac so that every hard aspect lines up, and how to read midpoints with the pointer.
The 90° dial is the Uranian astrologer's main working tool. It shows a whole chart on a circle of only 90 degrees, so that every hard angle becomes visible at a glance.
Folding the zodiac
Take each longitude and keep only its remainder after dividing by 90. A factor at 7° Scorpio (217°) and one at 7° Aquarius (307°) both land at 37° on the dial. So do 7° Taurus and 7° Leo.
Those factors are 90° or 180° apart in the zodiac. On the dial they are conjunct. Everything that is square, opposite or conjunct in the chart becomes a conjunction on the dial.
The dial is drawn with its 90 degrees spread over the full circle: one degree of the dial is four degrees of the circle. Factors 45° or 135° apart in the zodiac therefore appear opposite each other on the dial. One glance shows all eight hard angles.
The pointer
A dial has a pointer: a line through the centre, set on one factor. Its two ends point at the factor and at its 45° partner.
Any pair of factors placed symmetrically on either side of the pointer has its midpoint on the pointer's axis. That pair forms a planetary picture with the factor under the pointer.
Reading a chart with the dial means turning the pointer to each personal point in turn, and noting the pairs that balance around it within a small orb, usually 1°.
An example
In the sample chart used throughout this site (31 October 2006, 03:01, Bangkok), the Sun stands at 37.26° on the dial and Poseidon at 37.25°. They are conjunct, within 0.01°.
With the pointer on the Sun, the tightest pair balancing around it is Uranus/Kronos, within 0.02°. That gives the picture Sun = Uranus/Kronos.
In Hora Horoscope
The chart page draws the 90° dial for your chart. You can:
- set the pointer on any factor;
- choose the orb;
- show solar arc or transit positions on an outer ring.
The list next to the dial gives every midpoint on the pointer's axis, tightest first.
