Today I would like to revisit the theme of relationship astrology, and explore another method of determining compatibility between two individuals by the analysis of their astrological combination. Typically this is achieved through synastry: the application of one nativity to another wherein the aspects between each party’s placements are studied. Of course, even before any synastry is considered, a study of the individuals’ horoscopes will expose considerable insight, about the conditions of the marriage, the probability of marital breakdown and the manner of it, clues about the character and disposition of the marriage partner and so forth. I discussed this method previously in my article on the astrology of marriage. Another approach is to use a midpoint calculator and to combine the mundane placements of every discrete shared point in the respective nativities to produce a third nativity. This is an interesting and insightful method that I have discussed before, however, it fails in one very key context which in some ways is difficult to reconcile with the underpinning theory of the stars: namely that the mundane midpoint composite is an entirely academic horoscope: it simply cannot exist in nature. That is to say it is a mathematical construct and is not therefore a nativity that has ever existed in time and space.
This does not discount its relevance and valuable insights can be gleaned from the midpoint composite. What might be more intriguing however is to take an absolute midpoint of two nativities in time and space: thus by finding the exact point in time between two births and the exact geographical location which lies at the midpoint of the two individuals and from that point create an entirely new astrology; and crucially one that does exist in space and time. This is a complex method of combination known as the Davison Composite and named after its creator Ronald Davison.
Therefore, and to utilise a simple example, if you were born at midday on the 1st of January in London and your partner at midday on the 3rd of January in Glasgow, then you would create a nativity for January 2nd at midday, somewhere near Manchester to realise the Davison composite.
Previously I used the example of Prince Charles and Princess Diana as a midpoint combination to study the extant themes. Here then is the Davison Composite for their partnership:
This chart is not nearly so comfortable and easy as the mundane midpoint combination. There is of course a wonderful emotional power in the grand water trine, an easy sense of outward responsibility across the earth houses. This evidently creates a sense of emotional security derived from those themes of status, easy living and easy money. Jupiter on the midheaven and in Cancer, the sign of tradition, family and all matters clannish really tells a story of royal good fortune and benefit. The good news is decidedly thin on the ground after this point however.
The chart ruler is profoundly stressed most distressingly from Mars and if you consider this in tandem with Saturn in Scorpio, tee-squared from inflexibly autocratic Pluto in Leo and abruptly plain-spoken Mercury in Aquarius then you have a genuine difficulty that will no doubt manifest most especially in the bedroom. Saturn in Scorpio creates an early sexual difficulty: eventually there might be respite, but the lifetime arc of relationships creates pressure to normalise relations early on: a theme of discomfort or dissatisfaction in the sex-life will not long be tolerated in a marriage, at best it will become a major theme of anguish for both parties. Mars in Taurus too creates an astoundingly slow-fuse, here anger and resentment can build over months and that slow-pressure manifests out into the 8th: where sex is a matter of biological necessity.
Therefore, in outward appearance, with Libra rising and a grand trine in water, Charles and Diana would have appeared to be blissfully content, but with the passage of time and the pressure of so much unusual public scrutiny, the lack of any real chemistry and passion would eventually take its toll. Venus conjunct Chiron is very much the pain of love, and in the 4th and Aquarius, it is a behind-closed-doors woundedness that comes of feeling the pressure of convention and expectation; the expectation of needing to be exceptionally in love.
Venus, the ruler, squared (albeit widely) to Neptune rising, most especially speaks to this difficulty. Here is a longing for purity and refinement in the love experience but one that cannot be realised and thus grates and wears down the optimism. The dreamy perfection of matrimonial appearance that is hinted at by Neptune rising in Libra cannot live up to expectations and like a piece of grit in the shoe it niggles.
Another intriguing aspect not included in the chart depiction is Venus quindecile Jupiter. Venus Jupiter always denotes the joy of love, expanding and improving the underpinning themes of relationship; however, with the quindecile it becomes an obsession, and invariably a difficulty is realised as a result. It is of course difficult to derive too much darkness from any combination of Venus and Jupiter, most likely the problem is one of too much of a good thing rather than any constriction or agony, but here the obsession might manifest as an expectation of love that becomes a compulsion of simply having to look good for the cameras.
Lastly, Pluto is supremely difficult. In Leo, he is not an easy power to transform and again the idea that all must appear perfect even when there are severe difficulties in the foundations is mooted. Mercury – Pluto creates a very peculiar communicative tendency within the relationship where what is not said becomes more important than what is said. There is always a sense between these two people that something is being hidden and that more than any other factor is creating the sexual tension as evinced by the Me/Pl tee square to Saturn in Scorpio. Mercury squared to Saturn is the closest major aspect in the chart too, so here is a real brake on easy communication, Saturn in Scorpio creates a test of secrecy among other things and the square creates distrust and too much conservatism, especially for Mercury in Aquarius which really wants to be a little provocative and outrageous at times.
In summation, had I been consulted about this particular relationship, I would have been concerned that whilst there was much potential for an outwardly successful partnership, the appearance of happiness and contentment would very quickly belie a deeper malaise. A very real incompatibility in sexual relations would need some committed work and profound honesty to overcome in the longer term and the tendency for resentment to fester would eventually poison the initial ease inherent in the union. This was a relationship, that according to the Davison composite at least, was always going to struggle.
Wow, thanks for posting this highly detailed chart! I really enjoy reading your posts, I think most of them make a lot sense. I also dabble in some astrological stuff (see my blog 🙂 but nothing serious, although I do aspire to one day be able to be a serious astrologer, like you 🙂

Is this the corrected or uncorrected Davison chart? Do you it makes much difference if we use one or the other? Thanks.
