Reinhold Ebertin

his son, Baldur
Reinhold Ebertin, 1901-1988, came to Uranian astrology, and, according to the story, was denied permission to use the new Transneptunians in his work. So he reduced the Uranian system to the 90 degree dial, 45 degree graphic ephemeris and half sums (eg, midpoints). His use of these materials was brilliant. For those of you who don't know what these 45 or 90 degree things may be, the short answer is that they are methods of reducing all hard aspects to conjunctions on a wheel or graph. By means of this simplification, a powerful means of analysis was created. Here is what we think is a complete list of his available books:

Supplement, translated by Ise Hodges & Charles Harvey.

Comment: When the midpoint of two planets is aspected by a third (natal or transit), the result is a planetary picture. Everyone has some of these in their chart, they reveal much about the individual. This book is a comprehensive guide to some 750 & is essential for working with the dial. The text covers the Sun, Moon & planets, nodes & angles. Includes Ebertin's view of planets in signs & houses. With notes on Witte's concepts & the 1961 supplement to Ebertin's original book.

Comment: Back in print! Ebertin invented Cosmology. This is his own exposition of how it works, how the dial works, with many practical applications. An essential book, it has long been a classic. From the back cover:

This basic cosmobiology textbook was first printed in Germany (1949) under the title, The 90 degree Dial in Practice. After many additions & improvements it was released again in 1972 under the current title. Written by the acknowledged master, cosmobiology takes the fundamentals of the basic horoscope one step further by condensing the wheel to 90 degrees by placing the planets into their groups of cardinal, fixed and mutable. The analysis then becomes very simplified, yet with details that are astounding. Explained are the methods, interpretations, use of solar arc directions, graphic ephemeris and more. See for yourself how using cosmobiology makes astrology become a quicker and more useful tool.

Explanation of abbreviations


Relationships & the 90 degree dial. Ebertin first gives the natal charts on separate 360 degree dials, then puts both charts on one 90 degree dial and analyzes the resulting relationship. While the book has been entirely reset (and nicely, too), the charts and graphs seem to be from the original [German] edition, and are no longer very clear. (I used a magnifying glass.) I wish the AFA would take more care with their reprints, especially as 90 dials & graphic ephemerides can be produced by most good astrology software programs. For most of the examples in the book, you could construct the charts yourself, and then follow along with Ebertin.

- (C) Rashness, irritation, obstinacy, impulsiveness, quarrelsomeness, inclination to illness and mishap. In case of illness, high temperature. Extravagant demands, overstrain. (pg. 40)

Directions are based on the simple formula of one degree per year of life, but Ebertin notes that some theories make it exactly one degree, while others claim 57 or 59 minutes, or 1 degree 1 minute or two minutes, etc. How to chose the right one?

Ebertin says you don't have to. You take an event, note the progressed Sun's position as of that day & year (simple to do with computers), subtract the natal Sun from the progressed Sun to determine the age-arc, then divide that by the number of years that have passed, and, presto, you have the custom arc-per-year for that specific individual. You then apply it to the natal chart & note the other directions that will turn up. It's a useful trick to learn. I wonder if there are computer programs that will calculate it? (Not that it's all that hard to do manually.)

Ebertin uses the 90 degree dial (Contact Cosmogram) and 45 degree Graphic Ephemeris in his exploration of various charts and events. In Essential Configurations Ebertin gives many specific formulas, useful in forecasting. Directed Moon to the Venus/Saturn midpoint, for example, is bidding farewell, separation, renunciation (through illness), etc. A very useful section.

Comment: A regular ephemeris has a row of planets across the top, the days of the month down the side. If you want to know where Jupiter was on the 15th of the month, you look down the list of dates until you come to the 15th, and then look across until you come to the Jupiter column & the number you find there will be Jupiter's position on the 15th of the month in question.

A graphic ephemeris is diffent. It's graphic, for one thing. In a graphic ephemeris, degrees of the zodiac go down the side of the page, and the days of the year go across the top. Planetary positions are then plotted in the resulting grid of days & degrees.

The result are more-or-less horizontal lines (ie, planets) that run from left to right on the grid, sloping ever so slightly down as they do. Faster planets slope down more sharply than slower ones. Each line has its unique planet symbol to identify it. When two lines intersect, that's a conjunction. When a line reverses direction & goes up, that's a retrograde. Because the graph typically shows a full year, and as the moon makes a complete orbit every month, the lunar line is nearly vertical. It zooms straight to the bottom, only to emerge at the top at the same point in the zodiac as it held at the bottom, and then zooms down again. Every time it crosses one of the other lines, it marks a moon-to-planet conjunction.

Got all this?

Okay. Now make it a 45 degree graphic emphemeris. In a 45 degree graphic ephemeris, instead of 360 degrees going down the side, there are three sets of 15 degrees. The first set are the four cardinal signs, Aries, Cancer, Libra, Capricorn. The second set of 15 degrees are the fixed signs: Taurus, Leo, Scorpio & Aquarius. The third & final set of 15 degrees are the mutable signs: Gemini, Virgo, Sagittarius, Pisces. So, the first degree of the Cardinal section could be 1 or 16 degrees of Aries, or 1 or 16 degrees of Cancer, or 1 or 16 degrees of Libra, or 1 or 16 degrees of Capricorn. For the moment, you do not care which sign or degree it may be.

The resulting lines on this graph are much steeper than the 360 degree graph. Now, whenever you see two lines intersect, that intersection can be a conjunction, a semi-square (45), a square, or an opposition. Get out your ruler & draw a line from that point, to the top of the graph, and you will have the date of the resulting hard aspect. And it's the hard aspects that you want to find.

You can take this one stage further & plot natal positions on the resulting ephemeris. Natal planetary positions are horizontal lines, drawn from left to right. Whenever natal lines contact an ephemeris position, you have a transit. Whenever a bunch of ephemeris lines gang up on a natal line, or when various natal lines are attacked at the same time (check the vertical axis, ie, draw a vertical line), you have an event of one sort or another.

Still confused? See an example here. Louisa May's natal chart has not been drawn on this. Hit your BACK key to get back here.

Sound useful? It surely is. And not that well-known, despite the fact that all the major software packages (Solar Fire, Win*Star, Kepler/Cosmic Patterns) will easily do it. A woman in Arizona used to print beautiful, colored, legal sized pads for the year, and many, many years ago I used to sell them, but interest never quite caught on. Judging by my Solar Fire program, they were better than what the computer will do.

This book was previously titled, Transits: Forecassting Using the 45 Degree Annual Ephemeris. It had a Forword by Robert Hand, which this edition lacks. Aside from being reset, the two editions are identical in other respects.

Comment: How to rapidly select the most significant features in a Cosmogram, especially those which are important to the development of the individual. With numerous detailed studies, midpoint analysis & more. From the back cover:

The aim of a diagnosis is to assemble a comprehensive picture from a series of facts, draw the appropriate conclusions and from this make a prediction. A diagnostic delineation cannot deal with a Cosmogram in its entirety and consider its every detail, but it can rapidly select the most significant features and in particular those which are important to the development of the individual.

The master of Cosmobiology presents a guide to his system of forecasting the future through the use of progressions, solar arcs and transits, illustrated with case histories.
