Vertex - mundane calculations

Post by Jim Eshelman » Mon May 08, 2017 11:46 pm

(Originally posted 9/28/2012, 4:06 AM, years before I came back to work this out ore thoroughly.)

A few weeks ago, somebody asked me (in some thread or another) how to calculate when a planet crosses the Vertex-Antivertex mundanely, rather than simply measured in ecliptical longitude. I said I didn't know.

Tonight I realized how to do this in a forehead-slapping Doh! moment. It's super-easy with a chart calculation tool such as Solar Fire.

"Mundane crossing" of the Vertex axis means that the planet is on the great circle called the Prime Vertical. This happens when the planet's azimuth is 90° (east) or 270° (west).

Doh!

Now, I don't at all know that we should be calculating this mundanely. (None of us knows that since, until now, nobody had said how to do it.) But now we can start watching.

I came across a striking example - in my own chart, of all places! - to support my growing certainty that conjunctions and oppositions to the Vertex should be taken only mundanely, like other angles - measured in azimuth.

I consider Bryce Canyon in Utah to be the single most beautiful place on Earth I've ever seen. It draws me back with its beauty, majesty, and amazement. Relocating my chart to Bryce Canyon, there is a perfectly fine local contact of the Vertex to Jupiter and, if you step outside a partile orb, with Uranus. Here are the positions in longitude:

3°20' Can - Uranus
3°37' Can - Jupiter
4°22' Can - Antivertex

Fine enough. No serious objection other than that this sufficient hit isn't "anything special" of the sort that would mark out that exact spot - compared to all the area around it - as singularly unique.

However, view these in azimuth:

89°52' Uranus
90°00' Antivertex
90°09' Jupiter

Uranus is 08' on one side, Jupiter 09' on the other side: The prime vertical is the exact midpoint of Jupiter and Uranus to the minute! (Careful calculation for the front gate of the part gives an orb of 0°00'44".)

I would assume this only has effect in events and moments (not the natal).Its a rather intresting find either way!

Actually, the other way around. The importance of the Vertex in return charts and transits is, for example, just does't hold up, though the effect in the natal chart, while weak (compared to other things we normally trust), is pretty consistently demonstrable.

Ok intresting. I dont have access to my mudoscope does anything interesting appear in my chart (7:32 birth time if that's the one we recorded I don't remember).

As for the transits, would a transiting planet aspecting a natal planet partile to the vertex be more likely to function at an elevated energy level?

At 7:32 AM (instead of the 7:29 I had stored for you), Uranus is azimuth 90°08', i.e., 0°08' of Antivertex. I would expect this to be a strong expression in you of which you tend to be unconscious, i.e., it's not normally obvious to you how much you disrupt and displace things in your environment.

I wouldn't credit "energy" to the Vertex. Horizon and meridian confer that kind of expressiveness and high energy. The Vertex gives expression, but it has an inherent unconsciousness about it.

Unconsciously disrupts and displaces... great. Thanks Jim. It would make sense that I've missed this in my own chart, perhaps this will settle all qualms I had with my birth chart time. Interestingly enough Uranus-Venus midpoints my Sun and Uranus I believe aspects my Sun in the mundo (I've taken these with a grain of salt). Also could this unconsciously Uranus expression contribute to my psychic/ inter-cosmic tendencies(?).

I think the whole azmuith process just put a good perspective in my kind too. Knowing that Uranus is even more partile to an angle than my Sun, albeit these angles doing slightly diffrent things it's very intresting! Just feel kind of embarrassed that I over looked it 😶.

No need to feel embarrassed, I think. The nature of unconsciousness is to be unconscious :)

Here's the complex and technical relationship I think you're trying to describe:

For a 7:32 AM birth time, Sun is 0°42' below Asc in altitude (or 0°48' in PV longitude). Jupiter is 2°52' past IC in azimuth (or 3°14' in PV longitude). Uranus is 0°08' past Antivertex in azimuth or 0°07' in PV amplitude.

Now, this is technical... it may not be obvious why the math is this way... but here goes.

We take the Sun-Jupiter square in PV longitude. The orb of this mundane square is 3°34', which is a little larger than we normally take for this class of aspect, but you have Sun in Sagittarius anyway.

We take Sun-Uranus by comparing Sun's altitude to Uranus' PV amplitude. One is 0°42' before, the other is 0°07', so the orb is about 0°49', quite close for this birth time.

We take Jupiter-Uranus in azimuth. Uranus us 0°08' past, Jupiter is 2°52' past, so they are in PVP square within 2°44'.

Well that just kind of blew a hole in my chart Jim! The math makes sense if I think about the squares as straight tethers on a three demitional field.

Feels kind of cool that this azimuth calculating discovery opened the doors to this. I just don't know how to interpret the energy (does it read kind of like Uranus in the IC would read?). In terms if the Sun-Uranus [which of course sticks out, how should I interpret that?

More like Uranus to Asc except with the inherent unconsciousness. One would expect it to express naturally from you, with everyone else noticing it and you remaining oblivious to it.

My standard interpretation is: Go their own way, unapologetically following their own paths & persuaded that they’re a “special case.” Resourceful, stimulating, but easily bored (in need of frequent stimulation). Love of freedom: bow to no authority but themselves. Progressive, future-oriented, uninhibited by convention. Adept at creative problem solving. Self-perspective usually founded in objectivity.

Intresting again thanks! I'll read up on all of this further of course.

Side note this also ties together the "scorpio" bow I was looking for but couldnt find. Having a deep rooted aggression from my Mars/sign and (+moon) aspects, and having an angular Uranus together make my psyche run deeply with Mars/Uranus themes that they establish in scorpio (and the unconscious nature of Uranus in my chart kept me from putting it together). I wasn't ever a Scorpio of course, I just have similar thematics emerge in my chart.

It helps, of course, to have a settled birth time, and there has been such uncertainty about yours. Some of these things are only visible with a right time to within a very few minutes.

So, I have some follow-up questions in order to help me clarify my thoughts on your thinking about “Mundane crossing” of planets to the Vertex, regardless the type of “crossing” to a Vertex, and regardless the type of chart one was analyzing. For example:

When I compute the CapQ for Tokyo on March 10th 1945 (CapQ link below), and see that CapQ Uranus is 270,04 in Azi using Solar Fire, which if I understand means Uranus is mundanely partile cnj CapQ Vertex---Does this mean that in certain other cases with CapQ charts when our eyes see a partile cnj of a CapQ planet with the CapQ Vertex that it may not be in a partile mundane cnj??? In other words: We must always check the 'Reports' section in SF to make sure we are seeing a partile mundane cnj with planets 'crossing' the Vertex ?

Match to what happens with major angles: Within a given chart (natal, return, ingress), take mundanely. However, the mundane work has proven solidly that transits to angles are ecliptical and quotidian angle contacts are ecliptical (not mundane). One would expect Vertex to behave the same way as everything else.

Quotidian contacts should be taken ecliptically, not mundanely - presuming they work just like everything else.

However, I should add that a separate study, published here years ago, showed solidly that Vertex in mundane charts is worthless in terms of the angular contacts. It produces behavior quite the opposite of everything else, i.e., Venus and Jupiter contacts most common for deep tragedies BUT not at a statistically significant level. At first, seeing only that Venus and Jupiter were most common, my thought was that the Vertex-Antivertex was actively suppressing the planet, but then I calculated that it wasn't a statistically significant aberration. The correct interpretation of the data is that there is no demonstrable "angularity" type effect at all for planets in mundane charts.

However, while planets on Vx-Av in ingresses don't register as "angular," they are capable of forming mundane squares to planets on horizon or meridian and these are ENORMOUSLY important - equal in every respect to any other aspects we use. These are the "PVP aspects" I keep mentioning, as in the chart above.

Thanks Jim. So, if I understand, with your immense statistical work with Sidereal Astrology, we should pay attention to any possible mundane positions of our Natal Planets with our Natal Vertex for a given local. And then pay attention to the actual mundane position of transiting planets to our Natal Vertex?

Mundane in the natal itself (included relocated), but ecliptical (not-mundane) for transits. (Which is useful since I don't think you have a tool that can give you the mundane azimuth of a transiting planet with respect to your natal chart.)

Question Jim: In any CapQ/CanQ chart, would as our eyes view the Q charts alone-- all progressed partile planetary conjunctions to the Q Vertex be in mundane partile conjunction?

As mentioned above:

(1) No. All quotidian angle contacts work ecliptically, not mundanely.
(2) Additionally, the statistics are consistent with their being no relevance to Vertex in solar or lunar ingresses or the quotidians of the solar ingresses.

If it were conjunct mundanely, this would be so EXCEPT you only see the azimuth of the progessed ingressed planets, not the transiting planets. (I've seen a planet conjunct the Vx or Av in longitude but as much as 120° off in azimuth, or vice versa.

Partile ecliptical contacts do not at all guarantee azimuth conjunctions. They may be unrelated. They can be all over the map. Remember that Vx contacts in low latitudes are like Asc contacts in high latitudes, meaning you can get a lot of distortion.

But yes, the mundane conjunction with Vx/Av is the 270 or 90 in azimuth report.

As a general rule, is a true mundane planetary cnj with the Vx/Av a rare occurrence? Or, would your Natal Jupiter-Uranus mundo cnj your relocated Natal Vx in Bryce Canyon be the only place in the US this would occur? Your best guess--don't use any extra time to check.

There is a circle wrapped around the Earth where this contact will exist exactly is close. Just like there is a circle around the globe where a given planet is on Ascendant or Descendant, etc.

It is exactly as rare as, for example, the same planets being the same distance from ascendant.
