Walter Berg
Founder of 13 Sign Astrology

Our 13-sign astrology group is extremely honored and proud to present Walter Berg to our readers. Walter single handedly developed 13 sign astrology from scratch in the early 1970s. Before the advent of computers, he spend countless hours gazing at the night sky (with his dog as company) observing and tracking the movements of the planets, in real time, and against the backdrop of the actual 13 sign Zodiac. He then calculated their passage and transits using nothing more than a slide rule and a calculator, to create the first (and still the most accurate) 13 sign ephemeris.

His tenacity and devotion to the true Zodiac, which resurrected Ophiuchus from a 2,000 year banishment, was a supreme and solitary sacrifice, which put at risk his career in astronomy, and was ignored for decades by astrologers.

Walter also wrote extensively about the effects and meanings of the planets and the signs, not only beautifully expressed, but also creating the most accurate descriptions of the archetypes that we all use in our astrological methodology.

Only in the last 10 years has the Bergian Zodiac gained traction among both astronomers (including NASA) and the growing community of 13-sign astrologers. Adherents of 13 sign astrology in the U.S., U.K. and Japan have now taken up the torch, and validated his arduous work, ending years of rejection by tropical astrologers. Today several software programs feature the Bergian Zodiac. However, we at 13sign.com find his original software, astro22, to be the most accurate and comprehensive. For more on astro22, and how to download the trial version, click here.

It's a very lonely existence when you are so far ahead of your time, but he persisted against all odds. In the end, truth will out, and Walter's contributions and accomplishments make him the greatest living astrologer.

Here's an excerpt from his website:

"I break from historical tradition to combine sidereal astrology with the IAU’s official constellation boundaries defined in 1930, creating a 13-sign system. This results in astrological signs that correspond directly to the time the Sun spends in their eponymous constellations. For example, the Sun spends forty-five days in Virgo and only six days in Scorpio. The 13th sign of the zodiac is Ophiuchus where the Sun passes during the first two weeks of December.

I am an independent New Age scientist, astronomer, astrologer and educator, a founder member of the New Age science movement and the world’s leading authority and founder of Bergian Astrology (Bergian 13-Zodiac Astrology). My research examines links between personality, social behaviors, mass cultural change, blood type, planetary and star constellation positions, cosmic beacons, ley-line energies and feng shui. I present lectures and am consultant to several research groups."

Q and A with Walter Berg

Where you interested in astrology or astronomy first? Were you attracted to astrology for strictly historical or academic reasons, or because you believe we are affected by the positions and movements of celestial bodies?

Both - yet in very different ways. Reason and intuition! Astronomy is a hard science (perceptions of complex theories can be gained through intuition) but mostly the nuts and bolts are analysis, logic and reason. Astrology is not a science (not yet) it relies on our ability to understand something instinctively without conscious reasoning. The recognition of meaning in patterns etc. interpretation of astrological charts is derived from knowledge, experience and intuition.

Since the enlightenment scientists discomfort with intuition is based on cultural prejudice and more recently greater reductionism.  We know the collective unconscious/ collective memory instigates primitive mental images derived from our early ancestors. Jungian archetype culminates in the archetypal-self: the totally of wholeness. Wholeness is a transcendental wisdom and life should be lived as a psychic experience which will lead one to the realization of psychic wholeness. The people we meet in life are the result of meaningful coincidences – synchronicity is another Jungian concept.  In spite of our advances in science these areas/behaviors are still in the dark ages. Really understanding the unifying impact between living things and living things and the cosmos is a part of astrology and science. I am retiring and am introduced to you 13 Sun Sign and the Siderealists – synchronicity or meaningless coincidence?

Cosmic energies and human bio-resonant systems are still best interpreted intuitively. Little hard research has been undertaken in astrology. Gauquelin a psychologist from the Sorbonne undertook astrological statistical research which kind-of vindicated that there is a relationship between planetary positions at the moment of birth and the direction of individual lives. By today’s standards his method was crude and non-meta. Eysenk (whom I worked with briefly in the 80s) abandoned his research in astrology because of peer group demonetization. You leave the scientific straitjacket and are maligned by the established science community. Sagan, Feynman, etc. were notable exceptions.

My own research links with the work of Lakhovsky: living cells send and receive minute electric wave currents and display resonance. There is a biological and harmonic connection between our pulsating frequency and that of the earth/nature/cosmos. For example: Penrose argues that consciousness is a quantum mechanical process. This view further contributes to the underpinning knowledge of the wider astrology including second sight, precognition, clairvoyance, collective memory etc. Quantum entanglement and superposition may play an important part in the explanation of the conscious/unconscious mind. Penrose proposes a new form of wave function collapse that occurs in isolation with no decoherence. I digress- the connection to astrology and the psyche is entanglement, we receive information manifesting itself through insights and intuition.

The Apollo astronauts left retro-reflectors on the surface the moon. We have for fifty years measured the earth / moon distance to cm accuracy. The predicted orbit of the moon (Newtonian mechanics - by the way Newton, Kepler, Brahe, Copernicus etc. were all keen astrologers) did not match the observed orbit. A super-duper computer in Germany solved the problem - it was Sagittarius. The constellation of Sagittarius 38,000 light years distance influences the orbit of the moon. The moon has significant interconnections to human behavior and is swayed by objects at the far side of the galaxy.

Let me set the scene. It is the early 1950s my home is a small, rural, market town (Chorley) on the west flank of the Rossendale fells. I walk to the end of my road (200 meters) and I see the moors, Anglezarke in the near distance rising to 1000 feet. I can walk east for 60 miles over the moors and the peaks of the Pennines (peaks are 2500 ft?) without any signs of 20th century civilization. There is no light pollution (there are no electric street lights) the sky is pitch black and blazing with stars. Stars so bright you can touch them. I can see the Milky Way clearly and many fuzzy nebulae.  I feel connected to these celestial bodies on a spiritual, intuitive level and their energy affects me directly. I feel the energy of the cosmos (many cannot) and it touches me deeply. This connection extends from the cosmos to the earth and I become attached to the patterns, rhythms, circles and cycles of the seasons, nature and the cosmos.

My mother and grandmother were neo-pagans but did not know it. Their manufacture of talismans, amulets and placing of stones and crystals was governed by the phases of the Moon. Traditional medicine: herbs, berries, foliage etc. gathered from the moors would be prepared and applied according to the lunar cycle. Planting things that grow above the ground would be done when the moon was waxing. Planting things that grow into the ground was done when the moon was waning etc. etc. My mother was skilled when interpreting astrological signs and their meaning. She read tarot cards, tea leaves, playing cards, bones and observed cross and cross-quarter days. Astrology was with me not as a subject to be studied – it was part of my everyday life.

I just remembered: my mother was into theosophy and collected many old journals from the theosophical society edited by Annie Besant and containing the wisdom of Madame Blavatsky.

When and how did you first notice or realize that there was another sign on the Zodiac?

I am one of the few people to hold Astronomy ‘O’ Level. I sat the exam as an external candidate. I would have sat ’O’ level Astrology too but along with astronomy it was not taught in school and is still today not offered. In the 1950s calculation and positional astronomy were a big part of the syllabus. From the age of 14 I knew the Tropical zodiac was out of sync. I linked the sidereal zodiac and the IAU 88 constellations to bring astrological sign alignment into harmonization with the ‘true’ energy of the universe.  Astrology is kind-of taught in academia today through the study of cultural astronomy. The New Age science movement were responsible for its introduction t in the 90s.

Were you worried that your interest in astrology would compromise your career as an astronomer?

Absolutely and it did. My birth name is Barry Parkinson. I adopted Walter berg in 1980 when I began constructing charts and producing astro-personality profiles. Had my colleagues known they would have felt threatened which leads to hostility and me perceived to be dangerous?   It was a liberating experience. I could compartmentalize my interests easily by assuming two identities (especially in public) Walter was my grandfather’s name.

Did you feel weird, being able to entertain both schools of thought?

No. the problem was (is) always other people. Intuition and reason are of equal value and one should never dominate the other.

How did you create the 13 sign ephemeris?

From astronomical and celestial navigation charts / tables of value, a slide rule and many late nights. It took Kepler over 7 years to compute the orbit of Mars. Today a processor can compute the orbit of all the planets and constellations in milliseconds.

Do you have a favorite astronomer from history? What do you most admire about this person?

I do not have a favorite person. I admire all people who challenge with good cause the prevailing paradigm. They are usually considered to be heretics and often ostracized. From Anaximander to Einstein. One could list thousands - indeed Copernicus only published after his death to avoid being tortured to death. I admire them all. I know many were thoroughly unpleasant individuals but their single mindedness and brilliance are perhaps the qualities I admire.

What are you currently working on?

I continue to investigate communication systems looking at forbidden-zone transmission utilising subspace cosmic energy fields. My work examines the vacuum below the Higgs layers and Quantum Gravity layers to a structure upon which rests everything else. This structure is analogous to a fluid which theoretically can yield to modulation.

Astro22 Professional Astrology

Some years ago I consulted with Ramara House Software to develop a sidereal Bergian 13 Zodiac program (Ophiuchus) and a compatible Bergian 13 House system. The program is still readily available as a shareware download.

Astro22 Professional Astrology contains the Bergian 13 Zodiac with a companion Bergian 13 House option. With this you can produce a really aesthetically pleasing 13 Zodiac Wheel. You may wish to interpret yourself or you may use the integral basic interpretation.

Preceding the development of this software I calculated the Natal Chart the old fashioned way with a mountain of ephemerides tables, calculator and geometry set!
