Twin Differences
One Twin Normal
One Twin Autistic
by Sandra Weidner

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 another short, simple paper. It consists of three partial charts demonstrating the astrology for twins—a boy (Rodney) and a girl (Ryan)—born two minutes apart. The boy is autistic, while the girl is normal. Rodney was born first.

I have already discussed the astrology of autism in another paper. In order to make the most sense of this paper, the reader should read that paper first. Links to all the papers on autism are above.

I have written other papers on twins with the goal of identifying the differences in their astrology which accounted for the differences in their experienecs. Below are links to each of them :

When twins are very different--and only one twin being autistic is very different--but born only minutes apart, an astrologer is faced with a challenge. Born that close together, their charts are identical with respect to almost all astrological forms of interpretation.

In trying to account for their differences, then, she would first look at both their charts with the following questions:

(1) Do both charts look normal, or do both charts look autistic? Either answer raises the following questions:
(a) If they both look normal, then how could one twin be autistic? Where were his significators for autism?
(b) If they both look autistic, then how could she account for the fact that the girl was not autistic?

Of course, a condition that was completely sex-linked could account for the above difference. If autism occurred only among boys, then the twins could have autistic charts, and only the boy would manifest the autism.

But autism is not completely sex-linked. It occurs more often among boys than girls, but it still occurs among girls. So, off the top of my head, I cannot observe their charts to both look autistic but simply eliminate autism for the girl because she is a girl.

So, if their astrology is going to show the difference between them, it must be a minute, but concrete and unmistakable difference. With rare exceptions (see below), such a small time difference in birth in the same locality yields no appreciable difference between charts of anybody, twins or not.

The moon is the fastest moving planet in this form of astrology. So, close but different birth times would yield the most differences in the moon. Since the various harmonics multiply the original difference by the number of the harmonic, harmonic moons would show the greatest difference between two very close charts. And, the higher the harmonic, the greater the difference. The highest harmonic used so far in this method is the 14th, used for the 12th chart. Rodney’s b12 moon is at 6 Taurus 41. Ryan’s is at 6 Taurus 57. That is only a 16’ difference, not enough to make their lives so different.

The fastest moving parts of the chart are the Midheaven and Ascendant. A new degree of Midheaven passes over the horizon approximately every four minutes. So a two minute difference is going to yield a difference of about 1/2 degree. Below are the values for Midheaven (MC) and Ascendant (Asc) for both children:

Rodney10 Aquarius 550 Gemini 0924 Pisces 535 Cancer 31
Ryan11 Aquarius 28 0 Gemini 3825 Pisces 245 Cancer 55

Could these small differences account for their different conditions? Two minutes difference in birth puts the same life event about 6 months apart for each. So, in a perfect astrological world, if one married, then the other would marry six months later. But Angles are not the only thing in a chart which moves, so that "perfect" astrological world does not exist.

None of the above differences in Angles is useful in separating the autistic from the normal child. There are two reasons.

Angles, which are a form of light, have an orb of 2°. A difference of 30’ between Angles is highly unlikely to hit the significators for one twin and miss them for the other. It is possibly, but unlikely.

The above Angles could have shown a significant difference if the same Angle for each--say, birth Midheaven--had occurred in different signs. Sometimes the difference in birth times produce different signs on Angles, which will have different rulers. Different rulers gives us the possibility of eliminating the set which lacks the influential ruler. Different signs on different Angles happen when one twin is born with an Angle near the cusp of the next sign.

For these twins, the only Angle near the cusp of a sign is B Asc, which is in very early Gemini--0 Gemini 09 for Rodney. If Rodney had been born one minute earlier, his B Asc would have been at 29 Taurus 54, not in Gemini. Taurus is ruled by venus, while Gemini is ruled by mercury. If the significator set contained mercury, but not venus, then we would have the astrological basis for separating their charts because only one of them would have had the ruler in their set. As it turned out, however, neither venus nor mercury are part of their significators set for autism. So, even had they two different signs on the B Asc, it makes no difference in identifying their autism.

As a matter of fact, the latter astrological situation came meaningfully into play in separating a normal female twin from her retarded brother. More on that in that paper.

But, with Rodney and Ryan no such condition existed. So, we cannot fall back on a difference in sign on an Angle in order to differentiate them.

That leaves us with the question, what possible difference could there be which might separate this autistic twin from his normal sister?

The significator for autism is light/saturn/pluto influencing a 3rd house and an Angle in 1st and 3rd charts. Other planets may be in the set (and indeed often are-a measure of the multiple problems these children often demonstrate), but these are absolutely necessary.

When I first cast their charts, it looked like both were autistic. That is, both contained full, nearly identical, significators sets for autism in 1st and 3rd charts


The condition of their significator set for the 3rd chart provided the possible answer. The only light in the set was conception sun.

Prior to this pair of charts, I wrote papers on autism occurring among thirteen individuals. At that time, I did not pay attention to two factors which might affect significators. (1) I never differentiated between males and females. And, (2) I never differentiated one light from another. That is, if the set contained any one of the lights—sun, moon, node—then it was accepted as a set.

After looking at the charts of Rodney and Ryan, I returned to those thirteen previous charts to tally those factors. Below are my results:

All thirteen autistic individuals in the first and addendum papers are male. The high functioning autistic individual is female. The Asperger’s individual was a female. Although the last two are female, they are not completely autistic. Therefore, I have no charts of female autistics. So, too, I cannot check them to see if their significators differ in any way from those of the males.
Without female autistics, frequency distribution of lights in the significator set are of less importance, at least for this paper. Nonetheless, in checking, but without an exact count, I can state that the lights that occur in autistic significator sets (for all the males) are fairly evenly distributed among suns, moons, and nodes. Sometimes mercury, when it rules an Angle and acts like a light, is the fourth possible light. It appears from this that it makes little difference, with the 13 males, which light is part of the set.

But here we have a girl, not autistic, born only two minutes later than her autistic brother. Maybe there is some kind of "sex link" in their astrology which accounts for the difference?

Does astrology have planets which show sexuality? Yes, it does. Among the lights, a sexual difference occurs between the sun and moon. The sun has male attributes, while the moon has female ones.

In the 1st and 3rd charts those difference may hold very strongly because those charts are closer to the physical as well as psychological foundations of each individual. In the 7th chart, which describes our more adult personality, they may not. In a patriarchal society, the sun in a woman's chart describes the man/men (including husband, brother, father) in her life. The conditions of her moons show her life. In more modern, democratic societies which allow a wider range of expression to a woman, she may be expressing both her moon and her sun, that is, be expressing both her female and male attributes.

With our twins, we are dealing with the 1st and 3rd charts, where the sexual orientation of the light might be more powerful than in later charts. In these two charts, then, it is possible that the sun as the only light in the significator set refers to a condition implying something like: “this set applies only to males (sun).”

If the set applies only to males, then the girl with the exact same 3rd chart with the exact same significator set does not have a significator set for autism in her 3rd chart. She does not because the instructions in the set state that this condition applies only to males.

If her 3rd chart is lacking a proper significators for autism, then even if she appears to have a valid one in her 1st chart, it makes no difference. Autism requires that both charts have the significators set. In her case, we could say that that potential significators set for autism in her 3rd chart is “turned off” because of the presence of the sun in the set.

Before we look, below are meanings my research has yielded for the two charts involved:

The 1st chart is a chart which describes the identity we formed in childhood--how we see ourselves independent of our relations with others, in other words, our deepest, pre-verbal concept of ourselves. The 1st chart also contains indicators for various physical ailments, which can be seen as the somatic consequences of that early identity. Two examples are allergies and asthma. I am pretty sure, but have not finished the research, that alcoholism also shows strongest in the astrology of the 1st chart.
The 3rd chart shows intellectual talents and inclinations. It also shows various pathologies, including brain damage and other apparently physically-based mental disorders.

So, both charts contain astrological allusions to physical/emotional disorders. Often both must contain similar significators in order for a disease to manifest.

Here, too, is some definition of the 7th chart.

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 all kinds of information about our health, our finances, our career, our poetic ability, and so on.

The Twins
I usually present biographical information for subjects. These twins have famous parents. In order to avoid any possible privacy considerations, then, I have omitted all biographical information.

Their birth data came from Astrodatabank, who did not, however, state that one of the twins, Rodney, was autistic. That identification came from Astrologer Faith McInerney, who happened to be watching a television show when their mother was being interviewed.

Before looking at the charts, I want to make available information about this astrological 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.
Abbreviations used are b = birth, c = conception, and t = transiting. Even though the harmonic used for each chart is always two more than the chart’s number, in these papers I write the harmonic number the same as the chart number. For example, the 5th chart uses the 7th harmonic, but I have established the convention of writing harmonic planets for the 5th chart as, e.g., c5 mars, which reads, “the harmonic for the 5th chart for conception mars.

Now we can look at those charts. For each chart I have used the MCs and Ascs from Rodney’s charts. Ryan’s are listed above in the table.

The P Twins, the Charts
Since these twins were born only two minutes apart, I need only present one drawing each for their 1st, 3rd, and 7th charts. The main difference is in the degrees of their Angles, which I have shown above.

P Twins
Partial Harmonic Chart for the 1st House

Placidus: c11—0Tau, c12—5Gem, c2—28Can, c3—23Leo b11—14Pis, b12—23Ari, b2—22Gem, b3—15Can

Set (1) above is the significators set for autism. Please note that it contains four lights (b nodes, b moon, c1 nodes, and c moon), increasing orb enough to pull c1 saturn, at 20 Scorpio 56, into the same set with b1 pluto, at 28 Scorpio 00.

In Set (1) c moon rules C Asc. B moon rules b 3rd house. Containing lighted saturn/pluto with influence to an Angle and 3rd house, this Set (1) is positive in this chart for autism.

We move on to their 3rd chart.:

P Twins
Partial Harmonic Chart for the 3rd House

Placidus: c11—0Tau, c12—5Gem, c2—28Can, c3—23Leo b11—14Pis, b12—23Ari, b2—22Gem, b3—15Can

Set (2) above includes C MC, b saturn, c sun, and b3 pluto. The light in the approximate center of this set makes it into a set even though pluto is over 5° away from C MC.

In Set (2) c sun rules c 3rd house. C MC is the Angle that is already part of the set. This chart, then, is positive for the significator set for autism, but, only for males.

That really ought to be the end of it. However, now that we have differentiated between boy and girl based on an astrological form of sex-linking, the 7th chart has an interesting alternate interpretation.

P Twins
Partial Harmonic Chart for the 7th House

Placidus: c11—0Tau, c12—5Gem, c2—28Can, c3—23Leo b11—14Pis, b12—23Ari, b2—22Gem, b3—15Can

Set (3) contains C MC, b saturn. B7 mercury in Pisces, b7 moon in Sagittarius, c sun in Sagittarius, and c7 mars in Gemini. This set contains three lights—c sun, b7 moon, and b7 mercury (which rules B Asc and therefore acts like a light), therefore is within orb.

Set (3) shows MC/sun/moon/mercury/mars/saturn. It contains an Angle and influences another through b7 mercury, ruler of B Asc. B moon rules b 3rd house. C sun rules c 3rd house. So, this set is a forefront and powerful mental set. Because it contains mars and saturn, it shows dissonance and pain. Because it contains mercury, the difficulty in the set can be transformed into verbal and intellectual skills (as, for instance, is shown with editors).

Since, however, Rodney does not have mercury (thinking, speaking, writing) available (because of his two earlier, autistic charts), this set takes on the more painful interpretation for him.

For Ryan, the set works two ways. Since she has mercury skills available, it shows she has complex intellectual skills that get better as she gets used to handling the difficult part of mars and saturn together. At the same time, the dissonant and 3rd house part of the set, along with the mercury in Pisces, are descriptions of her less fortunate (Pisces) brother (3rd house and mercury), Rodney.

Both of them have the following set in their 7th charts (with only minutes differences):

Set (4)c moon23 Scorpio 13
b SN 24 Aquarius 23
c7 neptune 21 Taurus 17ruler of C MC
b7 neptune22 Taurus 37
b moon 26 Taurus 11ruler of b 3rd house

Angle/light/neptune/3rd in the 7th chart is the significators set for psychics (see paper on psychic, link on Home Page). Here, it might work several ways. For Ryan it might mean she is psychic. It could also act as a description of her brother (3rd house) as some one who is spaced out.

For Rodney, Set (4) likely represents himself as spaced out. Psychic abilities may not even develop in an autistic child. Or, they may, but would likely cause more trouble than good. It is difficult to be psychic unless one is well-balanced and solidly grounded. If that is not the case, then psychic information just adds more fuel to the conflagration of too much stimulation.

These twins, one normal and one autistic, can be separated from each other astrologically as long as we accept that in their 3rd chart, the presence of the sun (and no other light) in the significators set rules out girls by including only boys (sun).

If so, it raises the interesting question of why the reverse does not happen when the significator set contains the moon (female) as the only light. We know for a fact that it does not work that way because the moon occurs alone just as much as the sun and nodes in the charts of autistic males. Therefore, the moon’s presence does not dictate that “this autistic set applies only to females (moon).” In fact, it appears to act just the opposite, declaring the set operational for both males and females.
