The Chaldean Sunset Chart

The Chaldeans were simple and direct. They combined only seven planets against the patterns of stars. The timing of rising, culminating and setting for different planets and asterisms gave Chaldean observers the information they needed to establish their omens. They did this without using any elaborate house system. Yet the Chaldeans were famed throughout the world as the masters of the heavenly oracle.

In reflection of this though, we also want to be simple and direct. The sunset chart method recognizes that each complete house, consisting of 30°, is equal to a six-year period. Therefore, when timing events, especially at the moment transits or rogressions are being considered, the cusps of the equal house system provide a quicker "read" than any other house system. The equal house wheel is a time oriented device only.

The general overview is that we want to start from the point of sunset which is symbolically represented by the seventh house cusp. To readily see the aspects between the planets, we use a biWheel chart system with the exact same sunset positions in each chart. We then rotate the smaller chart inside the larger in a clockwise manner (into the sixth house then the fifth and so on). Each house has the value of six years. This will be explained in the following paragraphs. For now, cast a biWheel chart for sunset.
