The Importance of Astronomy for Astrology

The Importance of Astronomy for AstrologyIn episode 121 of the podcast astrologer Gemini Brett joins the show to talk about why it is important for astrologers to have some grounding in the astronomy underlying astrology, as well as some of the problems that can arise when they don’t.

In the first half of the show we discuss the separation between astronomy and astrology, and some different instances where understanding the astronomy underlying astrological chart placements can help to enhance or improve one’s understanding of astrology.

In the second half of the show we talk about some extreme instances where lack of education in astronomy has the potential to manifest in problematic ways in the astrological community, specifically focusing on the flat earth conspiracy theory.

This leads to some broader discussions about relativism in the astrological community, where to draw the line between belief versus science, and the relevance of certification or better standardization in our field.

    This podcast brought to mind two queries that I am wondering about. They relate to the origin of the planetary rulers of each sign of the astrological zodiac. First, were the sun and moon, the two celestial objects giving off the most light, chosen as the rulers of Leo and Cancer, respectively, because these two signs correspond to the time of year when the length daylight is maximum, i.e., the days with the most light? Second, the choices of which luminary would be the ruler of either Leo or Cancer seems intuitively obvious to me, but do you think that the ancient astrologers also made the choice of their rulers in a similar fashion?

    This is a standout show and should go on your highlight reel.
    I am familiar with Santos Bonacci. Loving the Scorpio vibe (I’m not a Scorp but Venus is my chart ruler, in Scorpio) — we love diving into these dark areas.
    I’ve heard, and have brief experience with to verify, that early Santos Bonacci was good. A lot like Brett said: thoughtful, eclectic, even if the words of Ronald Reagan ring true: “Trust, but verify.”

    He’s been co-opted. Happened after he went to jail about two years ago. I don’t know what “they” did, and it’s not worth speculating about on a professional avenue, but it’s clear something happened.

    This is commonly done among whistleblowers as a way to discredit everything they’ve ever done. But at a certain time Bonacci was legit.

    As a budding professional astrologer, however, how in good reason could I research Bonacci before Rudhyar? Tyl? So I don’t know Bonacci like *that.*

    A lot of Brett’s viewpoint of astrology parallels the great Jason Holley. As soon as you get him on, I’m a Patreon subscriber. Just sayin’.

  3. Great show! Very thought provoking on many levels. I appreciate Gemini Brett sharing some of his biography with us as I’ve seen his work online but haven’t known much about him. Also, this talk was one of the few times I’ve heard the astronomy of the primary and secondary motion discussed. Earlier in my studies I could see that planets and zodiacal signs on the chart moved in opposite directions but didn’t learned then that this phenomena has a name. For this upcoming this Full Moon, I’m eager to get outside and watch the Moon move in “both directions”!
