4. Lunar eclipses. These are figures erected for the time of Lunar eclipses, which are in reality Full Moons, and the exact moment of Full Moon is taken, not that of the middle of the eclipse. These figures are important, but less so than Solar eclipses, and they have a period of action extending over as many months as the eclipse is hours in duration. Their effects, like Solar eclipses, are chiefly to be observed in those countries the eclipse is visible, and in those places ruled by the sign in which the eclipse falls. A list of the specific effects of each Lunar eclipse in the various decanates of the Zodiac is given is a later chapter.
5. The conjunctions and oppositions of the planets Mars, Saturn, Jupiter, Uranus and Neptune. These are figures erected for the time of the conjunctions and oppositions of the these planets; and the house and sign position of such conjunctions and oppositions are to be noted. They are extremely important configurations, as their effects are very pronounced and lasting. They will be dealt with specially in a later chapter.
CHAPTER VII
HOW TO ERECT THE MUNDANE MAPS FOR FOREIGN PARTS.
As the subject of Mundane Astrology is principally intended for more advanced students, it is not intended to go into the matter of casting horoscopes and placing the planets therein, as these rules can be learned from the “Guide to Astrology,” or the “Key.”
Once the student can erect a map of the heavens for Greenwich the process of computing a figure for foreign countries is a very simple process, and it is particularly with this in view that the following simple rules and instructions are given.
Now as it is usually the practice, when making forecasts for the different countries of the world, to first cast the Mundane map for Greenwich and compute the planets’ places for this particular time, it follows that all other maps required for places other than Greenwich can be found by merely adding or subtracting the difference in time between Greenwich and the place required.
The rule is a very simple one and merely consists of finding the longitude of the place required, and turning it into time at the rate of one hour for every fifteen degrees, or four minutes for every degree.
If the place is in West longitude subtract this time from the Right Ascension of the Meridian at the Greenwich Map, and if East add the time. The result will give the Right Ascension of the Meridian for the place required.
Then with this Right Ascension, and a Table of Houses for the latitude of the place, erect the Mundane map in the same way as you would an ordinary horoscope.
