Introduction
As I have stated in other twin papers, twin births are especially useful to this astrology. Why? Parents of twins usually know before birth they are having twins, so they pay especial attention to birth time. They do so because later those time differences are a conversation piece as well as forming part of the identity of the twins. So, birth time for twins is likely correct to the minute and the charts cast from them are also close to exact. Comparisons made between them are then based on correct astrology. That means twin births are especially good for testing a major principle of this astrological method, that planets on (≤2° orb) Angles are of primary importance in describing all our lives.

When one twin has a different sign on an Angle, their births are also useful for demonstrating the principle that astrological sets (aspects) ruling an Angle are of far more importance than those which do not.

Examples of this are shown in the samples below and in all of the twin papers on this site.

This is a short, simple paper about one set of twins. It consists of ten partial charts—five for each twin—demonstrating the basic astrology for their difference for health, sexual preference, and employment. They were born twenty minutes apart.

I have written other papers on twins with the goal of identifying the differences in their astrology which accounted for the differences in their experiences. Below are links to each of them :
One Twin Normal, Other Twin Retarded

One Twin Healthy, One with Myasthenia Gravis

For these twins, the charts involved are:

The 1st chart is a chart which describes the identity we formed in childhood and some of its somatic consequences—allergies and asthma, for two examples. So, the 1st chart contains some health information.

The 5th chart contains information about our sexuality, our sexual preferences, and birth of children. In examining these areas, the 5th chart is combined with the 7th to yield maximum information in these areas.

The 6th chart is concerned with health and certain types of service, which can include spiritual service of the type called karma yoga. Dag Hammarskjöld’s 6th chart is an example of the latter.

The 7th chart, the main chart of this method, contains a great deal of information about our lives. Theoretically, it is concerned only with matters pertaining to the 7th house, such as our relations with significant others, including marriage and business partners and close friends. However, it, too, contains health information. The 7th chart is the main chart showing significators for Alzheimer’s and Parkinson’s disease. It also contains information on our career and social identity as well as our sexuality. So, this chart is consulted for all three differences between the twins—their health, their sexual preferences, and their work/careers.

The 10th chart is strong in showing information about our career, social identity, and relationship with our mother. It is combined with the 7th chart when we want to look at career differences between the twins.

Thus, in separating one twin from the other regarding the above issues, the following charts are consulted :

• For health, the 1st, 6th, and 7th charts
• For sexual preferences, the 5th and 7th charts
• For career, the 7th and 10th charts.

Instead of presenting each chart with each subject we are interested in—health, sexuality, career—I have presented the charts in ascending order by chart number. Since we are comparing two charts, I have presented each twin’s same chart number one after the other, with Twin No. 2 always presented first. Below those I discuss subjects covered by those charts. So, for instance, when we get to the 7th chart, all three subjects will be discussed under that chart, as will their significators. The headings for each chart also show which subjects are under the dominion of that chart number.

Biographical data from Astrodatabank is presented below. It is all the information I have, dated 1982, on these twin girls born in 1943. The first quote is about Twin No. 2:

”American second-born twin born 20 minutes after her sibling. Her sister is a heterosexual and in good health; she [Twin 2] is a lesbian who has had continual health problems. As an infant she [Twin 2] was weak and sickly. Diagnosed as having intercostal or lymphatic problems, she is unable to work for more than one month a year and has numbness of the face.”

The sheet for Twin 1 just states, “American first-born twin, a heterosexual in good health.”

Before showing their charts, it is necessary to present a few words about this method:

This astrology uses the sidereal positions of the planets based on the Fagan-Bradley’s SVP.

Harmonics are taken from the sidereal position of the planets. The Egyptian harmonic, discussed in the paper “About This Method” (see Home Page), is used.

”Lights” include suns, moons, and moons nodes.

This method uses only conjunctions, applying and separating squares, and oppositions. Orbs for planets with lights is 5°; without lights, about 2.5°. Orb for MC/planet or Asc/planet is 2°. Planets so related to each other are referred to as in the same “set.” A set, then, is two or more planets (or an Angle) connected to each other through conjunction, square, and opposition within the defined orbs. The set is more active if it contains a light, and less active without one. Learning to look in terms of “crosses” can be helpful in rapidly finding planets that are in the same set.

Because this approach uses both a birth and conception chart and they share the same axis, birth houses usually overlap different houses of the conception chart. These are called “house overlaps.” House overlaps play an important part in this astrology as investigation of the charts below (and in other papers) will show. Throughout this paper I use the convention when writing about house overlaps of putting the birth house first, then the conception house. So, for instance, a “5th/1st” overlap refers to an overlap of birth 5th house with conception 1st house in that order.

Birth planets (including their harmonics) rule only birth houses. Conception planets (including their harmonics) rule only conception houses.

For a more thorough explanation of this astrological approach, refer to this site’s papers entitled “About This Method” as well as the one entitled "Chart Reading Rules." There is also a link to the method paper at the bottom of every paper.

About This Method

Chart Reading Rules

In the partial charts shown below, birth planets and their harmonics are inside the circle. Conception planets and their harmonics are outside the circle. Conception sidereal planets are red; conception harmonic ones, black. Birth sidereal planets are blue; birth harmonic ones, green. Occasionally, because of space limitations, I have had to violate this inside/outside arrangement, but the color coding remain constant.

Before I can present their charts, a short discussion of same sex relationships and the data available on them is necessary.

Significators for Lesbianism
Papers are now written on bisexuality, lesbianism and homosexuality, for the latter two using charts of fifty individuals in each. They explore the effect of neptune on venus and mars. Rather than presenting the same information in an abbreviated form here, I refer the reader to those papers. Here are their links: Paper on Homosexuality, Paper on Lesbianism, Paper on Bisexuality and Modification of the Significators for Same Sex Attractions, and Addendum to Paper on Bisexuality--17 More Charts.

Light/venus/neptune is very high in the charts of lesbians, just as light/mars/neptune is very high in the charts of homosexuals. In fact, they appear necessary first parts of significators for same sex preferences. Often enough each group shows the full combination—light/venus/mars/neptune the chart that contains their significators for sexuality. Venus and mars both correlate with sexuality, venus with the female (or feeling and receptive) part of sexuality, and mars with male (projective) part of sexuality. Combined with these, neptune’s influence heightens the excitement, inflames the feelings, makes them tender, and sometimes renders the object of their affections as (too) precious. That is, neptune puts a big charge on the significators for sexuality.

With lesbianism, Angle/light/venus/neputne/5th/(7th), most often in the 5th, 7th, or 12th charts, is the significator of the first part for lesbianism. It can also occur in other charts, but when it does, it must be with the second part of the significator in order to comprise valid sets representing the astrology of lesbianism.

A second part of the significator exists. I write it as "venus/Desc" in the 5th or 7th chart. But the same thing occurs astrologically with any of the following sets: venus is conjunct an Angle which is in a 5th or 7th house, or venus is in a 5th or 7th house and made Angular by any of the four Angles of this method (4° orb), venus is anywhere in the chart, rules or co-rules (1/3 of the house) a 5th or 7th chart, and is made Angular by any of the four Angles of this method, and, finally, venus is conjunct any Angle and is also in the same set with a ruler or co-ruler of a 5th or 7th house. All of these astrological conditions put venus/female consciousness forefront (Angle) in the chart and connect it to sexuality or close partnerships (5th or 7th house). They identify that the consciousness of the individual thinks in terms of (Angular) a female (venus) partner.

This second part of the significator "counts" when it occurs in the 5th or 7th chart regardless of which chart the first part falls in. For it to count in charts other than the 5th or 7th, it must also be in the same chart with the first part of the significator. So, above I mentioned the 12th chart high in incidence of significators for lesbianism. In order for that to be true, it means that chart contains both the first and second parts of the significator for lesbianism.

While significators for lesbianism occur most often in 5th, 7th, or 12th charts (see paper on lesbianism), they can occur in any chart that ends up being a center of gravity (COG) chart of the individual. When an individual has a consciousness that is centered in some chart other than the 5th or 7th, it becomes their COG. One lesbian example is kd lang, whose COG chart is her 10th. And it is her 10th chart that contains both her first and second parts of significators for lesbianism.

So, all charts other than the 5th or 7th which contain significators for the second part of lesbianism must also contain the first part of the significator in order to be valid. But, any chart can contain the first part of the significator for lesbianism and not the second so long as the second part is contained in either the 5th or 7th chart.

Both parts of the significators for lesbianism must occur in order for the consciousness to be lesbian. The first part of the significator (by itself) also occurs in charts of heterosexual women. And the second part of the signifacotor (by itself) can occur in any one's chart without having any lesbian significance.

With the above identification of significators, we have enough to separate Twin No. 2 from Twin No. 1 with regard to their sexual preference.

Now we can start looking at their charts. Twin No. 2 is the ill, lesbian, unemployed one. Her chart is presented first each time, followed by that of her sister. Discussion of the astrology supporting their differences follows both charts.

The important set in both charts is Set (1). Note that for Twin No. 2 both her C MC and her C Asc are in a set which contains moon/moon/mars/jupiter/jupiter/saturn. While the two jupiters undoubtedly ameliorate any health issue connected to this set, Twin No. 2 still has doubly lighted mars/saturn to two Angles. Even though none of the planets rules a 6th house (or an Angle), Angle/mars/saturn is potentially about illness. Saturn, in particular, depresses health.

Twin No. 1’s Set (1) shows only moon/mars in the same set with C MC and C Asc. Angle/mars can sponsor inflammation, but does not depress health. In theory, the set includes neptune. Moon/mars/neptune is involved in allergic reactions. But, since this neptune is retrograde, it is not of much importance and is not included in the set. None of the planets in this set rules an Angle.

Neither chart above, by itself, actively promotes ill health. More is needed, and more shows up in later charts.

I included Set (2) in Twin No. 1's chart because it shows an Angle/sun/pluto, but it has no health significance. Set (2) will come up later when we are looking at their 10th charts.

Set (1) in both charts is interesting. For Twin No. 2, it shows B MC in c 5th house in close conjunction with NN, moon, and mars in Capricorn, making her sexually very aggressive. Her close conjunction of mars/node/moon to B MC in c 5th house suggests a strong emphasis on the male (mars) part of her sexuality if she also has the first and second parts of the significators for lesbianism. It may represent a high degree of circulating testosterone. (See below).

Twin No. 1’s Set (1) shows c5 mars over 4° from B MC still in c 5th house. Her mars is “buried” (a) away from the Angle, and (b) well inside c 5th house, so she is less sexually aggressive..

[This section on the 5th chart was updated March 30, 2011.] Set (3) is nearly identical in both charts. Here it is:

The only difference between Set (3) shown above and the same set in Twin No. 1’s chart is that the latter’s c venus is at 1 Gemini 47 (only a 1’ difference), and her c5 moon is at 1 Sagittarius 40 (a 1° 18’ difference). Both sets influence B MC in c 5th house. This is a 5th chart first part of the significator for lesbianism. Both twins have it.

Looking at Set (2), it is the same in both charts, I just did not show it in Twin No. 1’s chart. It is the same, except that Twin No. 2, the lesbian, has Set (2) on two Angles, C MC and C Asc. C mercury rules those Angles (and is included because when mercury rules an Angle it acts like a light and extends orb from the 2° to 5°) and C Asc is in b 5th house. So Set (2) shows an Angular venus with influence to a 5th house. It acts as the second part of the significator for lesbianism and is valid only in the chart of Twin 2, which is why she is a lesbian and her sister is not.

Set (1) is again the main set for each chart.

In twin No. 2’s chart we see that C Asc and C MC are in the same set with moon/jupiter/saturn. Since C MC conjunct jupiter is in b 2nd house, this part of the set probably sponsors the financial assistance she gets while ill and unemployed. It suggests she was fortunate (jupiter) financially (2nd house).

Still on Twin No. 2's Set (1)...her C Asc, is conjunct moon/saturn in Virgo. Lighted saturn on an Ascendant suggests a depressed (saturn) health (Asc). So does saturn in Virgo on the Asc. Virgo is the natural sign of the 6th house, and is correlated with health issues. This is the astrological condition, possibly in conjunction with her 1st chart which also has lighted saturn (in Virgo) influencing C MC and C Asc, which identifies her health problems.

Her sister’s Set (1) includes only C MC, C Asc, and b6 sun. She has no Angle/saturn in her 6th chart. Nor in her 1st chart. These show an absence of the significators (saturn in Virgo and saturn/Asc) for health problems.

In regard to healthy, the primary set in each chart is Set (1). Twin No. 2, who has health problems, has two moons and one saturn in Virgo on C Asc. Those show depression (saturn) of health (Virgo/Asc).

Twin No. 1’s Set (1) shows a set containing C MC , C Asc, moon/moon/jupiter. We can state it that way, or simply observe that she has a doubly lighted jupiter in Virgo on C Asc, showing just the opposite of her sister. Jupiter (good luck and harmony) in Virgo (health) on the Asc (health).

In regard to employed, Set (1) is still the operant set. Some one with doubly lighted saturn on an Angle (Twin No. 2) is going to be less fortunate in employment (indeed, in most things) that some one with lighted jupiter there (Twin No. 1). That is in addition to the additional fact that some one who is ill a lot (Twin No. 2) is less employable than some one who is healthy (Twin No. 1). There is more on employability in the 10th chart…

Although I did not number it as a set, Twin No. 1 has a final set worth comment in this, her 7th chart. Her b7 SN in Capricorn is conjunct B MC which is in c 5th house. (For Twin No. 2 b7 SN in Capricorn is nearly 6° away from B MC.) This shows an apparent strong need (SN) to be in control (Capricorn) sexually. Indeed, if we look at it simply from the perspective of B MC conjunct SN (without paying attention to the fact it is in c 5th house), Twin No. 1 just has control issues. As far as I know, control issues do not “belong” to either straight or lesbian women. Control, perhaps sexual control (5th house), and perhaps social ambition (Capricorn), are more important to Twin No. 1 than to her sister.

Two sets in this chart point to identifiable differences in employability between the two women.

In Set (1) in Twin No. 2’s chart we see C Asc conjunct moon/pluto/pluto. In the same set are C MC/jupiter/neptune. But we are mainly concerned with the Asc conjunct moon/pluto. It shows an individual who is guarded, held back, tentative, and/or acting as if rejected. This chart also shows something about our relationship to our mother. So this set suggests this twin was, in some fashion, rejected. It might not have been rejection, but being over-protected. Either way, it did not happen that way for her sister. Such hesitancy, even lack of self-confidence, is too guarded to be good for social interaction.

Indeed, we cannot be sure that Set (1) is not part of Twin No. 2's signature for lesbianism. I am aware some years back homosexuality was declared no longer a neurosis. I assume that change included lesbianism. So, if this set is part of Twin 2's signature for lesbianism, it is not so much because she is neurotic (any more than the rest of us, that is), but that an unknown percentage of lesbians have distaste for their actual mothers. It is the same with men. An unknown percentage (I do not know if any one has figures on this) of homosexuals adore their mothers and have no use for their fathers.

Remember that C Asc in her 7th chart was conjunct moon/saturn, also negative for social interaction and social approval? These plus her bad health all work against good employment.

For Twin No. (1) Set (1) is positive. Her C Asc is conjunct c10 North Node. North Node conjunct either Angle is very positive for social approval and the success of “doing the right thing at the right time.”

In the 1st chart for this twin I put in a Set (2) which shows B MC in the same set with b sun, b pluto, and b1 jupiter. I put it in there to show that this twin also has pluto to an Angle. But hers in on the 4th cusp and is non-harmonic. It was in play in her early years, and will come into play again toward the end of her life (4th). The moon/pluto/pluto conjunct C Asc in Twin 2’s 10 chart (that is, this chart we are considering now) have harmonic plutos. They have a specifically 10th chart meanings, and are at play during the years of her career.

The remaining set is not much, but still, I think it comes into play in the differences between them in career.

For Twin No. 2, Set (2) shows b moon in b 9th house. Twin No. 1 has it in b 10th house. Moon in the 10th house shows an individual who works with the public or who is well-known publicly, markers of an active career and social image. Not so, moon in the ninth house.

Conclusion
In her 1st chart, Twin No. 2, the unhealthy one, has two Angles to lighted mars/saturn. This plus the affliction of her C Asc with lighted saturn in both her 6th and 7th charts are more than sufficient to identify her as the unhealthy twin.

Twin No. 2’s stronger (closer, smaller orb) moon/venus/mars/neptune set in her 7th chart and 5th charts, along with North Node conjunct mars conjunct B MC (which is in c 5th house) in her 5th chart go a considerable distance in separating her from her heterosexual sister.

Finally, Twin No. 2 has moon/saturn conjunct C Asc in her 7th chart and moon/pluto conjunct C Asc in her 10th chart are both depressors of social interaction. When we withdraw, we also experience rejection. Which comes first is a good, but not necessary, question.

Compared to Twin No. 2, Twin No. 1 has moon/jupiter conjunct her C Asc in her 7th chart and North Node conjunct C Asc in her 10th chart, which are both positive indicators of social interaction, good timing, social approval, and success.

These sets in charts 7 and 10 for each twin are sufficient to separate them according to the one twin being very employed and the other suffering from considerable underemployment.

Discussion
While lesbian birth data lets us know the individual’s preference for a same sex partner, it does not let us know the sexual identification (if any) of the lesbian. This makes research more difficult than it need be.

While some (an unknown percentage of) people are bisexual, gender preference is most often a matter of "yes or no," a bipolar thing. Sexuality is not so conveniently sorted into two poles. Sexuality, it appears, occurs on a gradient from very male to very female in all the sexes, with neutral or indifferent being in the middle. This, too, complicates research, especially since we have no universal scale of measurement of male-through-female. Presumably the scale is there. Presumably it exists in the individual’s astrology. If so, we are still in a Catch 22 about it. We need better personal data. That means good research would include not just the individual’s sexual preference, but how they really feel, what they really do. This applies to all individuals, not just same gender couples. Then we could see if all their preferences were indicated in their astrology, which would then comprise the universal scale.

That sexuality occurs on a gradient is one of the points made by this paper. Of nearly identical sets, Twin No. 2 had the stronger ones for lesbianism.
