An astrologer needs the exact time and place of your birth in order to construct and interpret your horoscope. The illustration on the next page shows the flat chart, or natural wheel, an astrologer uses. Note the inner circle of the wheel labeled 1 through 12. These 12 divisions are known as the houses of the Zodiac.
The 1st house always starts from the position marked E, which corresponds to the eastern horizon. The rest of the houses 2 through 12 follow around in a “counterclockwise” direction. The point where each house starts is known as a cusp, or edge.
The cusp, or edge, of the 1st house (point E) is where an astrologer would place your Rising sign, the Ascendant. And, as already noted, the exact time of your birth determines your Rising sign. Let’s see how this works.
As the Earth rotates on its axis once every 24 hours, each one of the twelve signs of the Zodiac appears to be “rising” on the horizon, with a new one appearing about every 2 hours. Actually it is the turning of the Earth that exposes each sign to view, but in our astrological work we are discussing apparent motion. This Rising sign marks the Ascendant, and it colors the whole orientation of a horoscope. It indicates the sign governing the 1st house of the chart, and will thus determine which signs will govern all the other houses.
To visualize this idea, imagine two color wheels with twelve divisions superimposed upon each other. For just as the Zodiac is divided into twelve constellations that we identify as the signs, another twelvefold division is used to denote the houses. Now imagine one wheel (the signs) moving slowly while the other wheel (the houses) remains still. This analogy may help you see how the signs keep shifting the “color” of the houses as the Rising sign continues to change every two hours.
Once your Rising sign has been placed on the cusp of the 1st house, the signs that govern the rest of the 11 houses can be placed on the chart. In any individual’s horoscope the signs do not necessarily correspond with the houses. For example, it could be that a sign covers part of two adjacent houses. It is the interpretation of such variations in an individual’s horoscope that marks the professional astrologer.
But to gain a workable understanding of astrology, it is not necessary to go into great detail. In fact, we just need a description of the houses and their meanings, as is shown in the illustration above and in the table below.
