Franz Hartmann offers an alternative method to setting up a geomantic theme or chart. He associates different astrological signs to the geomantic figures and he has a different method of calculating the Judge or the Indicator. He also outlines the basics of Astronomical Geomancy. His book Geomancy appeared in 1889 and again in 1913. Although never that popular, his methods give an alternative that some follow.
The folowing are the associations of the geomantic figures to the astrological signs according to Franz Hartmann.
Franz Hartmann gives the Agrippa's method for placing the figures into the chart. The Mothers go into the 1st, 10th, 7th and 4th Houses (the angular houses). The Daughters go into the 2nd, 11th, 8th and 5th Houses (the succedent houses). The Nephews (Nieces) go into the 3rd, 7th, 9th and 6th Houses (the cadent houses).
He then places the astrogical sign related to each geomantic figure all around the outside of the chart. Inside each house alongside the the geomantic figure, he places the associated planetary sign for each figure.
The Judge of the Indicator
Hartmann constructs the figures by drawing a random line of dots or punctuation either on paper or in sand. If the line has an odd number of dots it gives a single point for one of the lines of the geomantic figure (these lines are used to create the four Mothers).
If the line has an even number of dots it gives a double point for one of the lines of the geomantic figure. All of these many dots or punctuation that have been drawn are also used to calculate the Judge or Indicator.
Add all the dots or punctuation together and divide by 12. The remainder indicates the house where the Judge or Indicator is found.
