A Merlin report summary

Ever since I first saw astrology websites, I have looked to the Merlin Report as a means of looking at what astrology supposes people to be like - and always laughing hilariously whether it’s true or not!

One of the interesting features - in an odd way prophetic since demoted Pluto was never included - is that when certain planets conjunction a certain Ascendant, the delineation is revised because the original delineation for the conjunction is inappropriate, as with a Gemini Moon conjunct Ascendant. (It also sometime happens that an out-of-sign conjunction will alter the standard report).

The following table shows where the “normal” delineation is altered for each Ascendant (first column). Red cases indicate it is, green indicates it is not, and yellow indicates doubt (with Sun conjunct Ascendant in  I have often imagined it would have a special delineation but what I have seen may contradict this though the report may have been different or taken as I do from the web).


Another thing is that when a planet aspects certain pairs of planets, there is an additional delineation (Sun aspects A and B). This never occurs when a planet aspects Pluto in addition to another planet, nor when Jupiter or Saturn aspects more than one planet further out. Thus, we can limit this second Merlin Report summary table to planets from the Sun to Mars aspecting planets from the Moon to Neptune. In fact, there are none of these delineations relating to an aspect between the Sun and Moon in the Merlin Report, but I have included it for completeness.

What is clear here is that it is primarily aspects to Jupiter (representing growth) and Saturn (limitations) along with those between Saturn and Uranus (originality) that are noted by Merlin.

These two tables should help understand astrological reports for those who do not.

Bias in Astrotheme data?

One interesting study I did today was to see if there was bias in the relationship between Sun and Ascendant signs in Astrotheme data. Most astrology sites that do natal interpretations base data with unknown birth times on a midday birth, which means the Sun will be conjunct the Midheaven. Of course, in most cases where the birth time is unknown it will not have occurred around noon. In order to test whether there is this sort of bias even among “known” (which includes doubtfully known) birth times, I have had a look on Astrotheme at a list of people born with Moon and Ascendant in the same sign and tabulated how the full list compares to the Sun sign by aspect:
  • Zero signs: conjunction, or a “triple” with Sun, Moon and Ascendant in same sign
    • Only 136 celebrities out of 18,520 (0.73 percent) were born with Sun, Moon and Ascendant in same sign
    • This equates to one in 136, not significantly different from the predicted one in 144
    • Another 1,413 celebrities (7,629 percent) were born with the Moon and Ascendant in the same sign but the Sun in another sign
      • It is notable how often this occurs among people near me, including myself: 5 of 56 people close to me or my brother have Moon and Ascendant in same sign, but there are no “triples”.
  • Positive one sign: the Sun sign is one sign after the Moon/Ascendant sign; e.g. ☉in ♌ with ☽ and Ascendant in ♋.
  • Positive two signs: the Sun sign is two signs after the Moon/Ascendant sign; e.g. ☉ in ♐ with ☽ and Ascendant in ♎.
  • Positive three signs: the Sun sign is three signs after the Moon/Ascendant sign; e.g. ☉ in ♌ with ☽ and Ascendant in ♉.
  • Positive four signs: the Sun sign is four signs after the Moon/Ascendant sign; e.g. ☉ in ♍ with ☽ and Ascendant in ♉.
  • Positive five signs: the Sun sign is five signs after the Moon/Ascendant sign: e.g. ☉ in ♏ with ☽ and Ascendant in ♊ (as in my own chart)
  • Six signs (positive or negative makes no difference): the Sun sign is opposite the Moon/Ascendant sign: e.g. ☉ in ♈ with ☽ and Ascendant in ♎.
  • Negative five signs: the Sun sign is five signs before the Moon/Ascendant sign: e.g. ☉ in ♓ with ☽ and Ascendant in ♌.
  • Negative four signs: the Sun sign is four signs before the Moon/Ascendant sign: e.g. ☉ in ♑ with ☽ and Ascendant in ♉.
  • Negative three signs: the Sun sign is three signs before the Moon/Ascendant sign: e.g. ☉ in ♐ with ☽ and Ascendant in ♓.
  • Negative two signs: the Sun sign is two signs before the Moon/Ascendant sign: e.g. ☉ in ♍ with ☽ and Ascendant in ♏.
  • Negative one sign: the Sun sign is one sign before the Moon/Ascendant sign: e.g.☉ in ♌ with ☽ and Ascendant in ♍.
Tabulating all the possible combinations as explained lengthily above gives the following result:
What one sees is that there is:

  1. a very distinct peak three signs before the Moon/Ascendant sign
  2. a less distinct though significant trough five signs before the Moon/Ascendant sign
These suggest that, in spite of efforts to exclude those with unknown birth times, astrology databases still have some problems of bias.

One way possibly of dealing with this problem would be to make sure that birth times are not taken as noon when unknown, and only to take a noon birthtime from a birth certificate, biography or correspondence. Whether this will help correct the bias from the simple test above is a fascinating question.
