Alan Leo and the Orbs of Aspects

"The time has come to modernise the ancient system of Astrology" said Alan Leo in the first issue of Modern Astrology in August 1895, "It is our intention in these pages to introduce the science of astrology in its true aspect...So astrology, or the law which rules life and destiny, will be presented with renewed life and vigour to an awakening mental and spiritual world." (1)

One result of this "modernisation" was to redefine the meaning of the term "orbs". The ancient belief that planets themselves had orbs was changed completely. Leo stated that it was the aspects, both major and minor, that had the orbs. This alteration has resulted in a confusion that has persisted throughout all branches of astrology to the present day.

It is generally understood that the Arab astrologer Al Biruni was the first to write that the planets had orbs. He stipulated that Saturn and Jupiter had a 9 degree orb. Mars had an 8 degree orb, Mercury and Venus had 7 degrees each, the Sun had a 15 degree orb and the Moon's orb was 12 degrees. These were accepted more or less by astrologers throughout the astrological world until the end of the 19th century when Leo decided to revolutionise astrology. (2)

The method for calculating whether two planets were in major aspect was to add their orbs and divide by two. This was called the moiety of the orbs. Claude Dariot (1533-1594) the French astrologer, in his book "A Breefe and Most Easie Introduction to the Astrological Judgement of the Stars" gave the following example regarding the Moon and Saturn in sextile to each other, "half of the circle of Saturn is 4 degrees 30 minutes, and half of the circle of the Moon is 6 degrees, if then these parts be joined together, which mount to 10 degrees and 30 minutes, the applications will easily be found. Likewise must you judge of all other aspects of the planets." It should be understood that Dariot was only referring to the major aspects and not to the minor ones. (3)

Leo was certainly familiar with the practise of older astrologers in regard to orbs, people such as Lilly, Gadbury and Partridge, as well as the mid to late 19th century astrologers Simmonite, Zadkiel and A.J.Pearce.  In Horary Astrology he wrote that he had copied the orbs of the planets directly from The Science of the Stars. (4) Yet in Modern Astrology, dated Oct 1895 two months after his declaration, he published the third chapter of an article entitled "A Simple method of Instruction in the Science of Astrology" in which he wrote "you may call 94 degrees a "square aspect" or 86 degrees; in the former case it will have separated by 4 degrees and the latter applying to a complete aspect, but four degrees away from it". Later he wrote, "A conjunction is the position of two planets that are within five degrees of each other." (5)

He made further changes in 1909 in his book "Horary Astrology" when he wrote, "When two planets are approaching conjunction or opposition, add the orbs of the two together and then take half the sum; this will give the distance at which the two planets will begin to influence one another. Thus the influence of Moon conjunct Venus commences while they are yet 10 degrees apart, 10 being 12 plus 8 divided by 2".

"For square and trine allow 3/4 of above orbs, for sextile, semi-square and sesquiquadrate, ½ only". (6)

He neglected to mention the semi-sextile and quincunx and the supposed orbs that were to be allocated to them.

The obvious point about Leo's approach to orbs was his inconsistency. He continually changed the number of degrees for the orbs of aspects. In the library of the Astrological Lodge of London at the Astrology Study Centre there are two type - written volumes, undated, containing Alan Leo's Astrological Lessons. The lesson concerning orbs shows once again that he was uncertain as to how to calculate them. "For conjunction and opposition allow 12 degrees when the Sun aspects the Moon; 10 degrees when the Sun or Moon aspects a planet; and about 8 degrees when two planets aspect each other.

For square and trine allow 8 degrees all round; for sextile 7 degrees; for sesquiquadrate and semi-square about 3 degrees. For the weaker aspects only allow 2 degrees. For the parallel not more than 1 degree." (7)

Furthermore, in Casting the Horoscope published in 1912, he wrote that the major aspects had an orb of 5 to 7 degrees and all others not more than 2 to 3 degrees. He thought that "the conjunction and opposition may be considered, in the case of the Sun, when within 12 degrees. If planets are further from aspect than this it is advisable to regard them as "applying to" or "separating from" an aspect, rather than as being actually in aspect". (8)

It is evident from the above that he had been in some confusion for a number of years as to exactly which degrees to assign to the orbs of aspects. Yet this confusion is undetectable in his work as he writes with apparent confidence when stating the number of degrees for each aspect, discarding one set of orbs after another as time went by.

Somehow, Leo managed to persuade Raphael (9) and Sepharial (10) that his "orbs of aspects" concept was worthy of endorsement since variations of it appeared later in their writings. Still, they had their own views on the matter and it was a number of years before Raphael abandoned the traditional method outlined in his book Horary Astrology. He had presented the traditional method of determining the orbs between two planets while adding Uranus, but omitting Neptune. "Uranus is 8, Saturn is 8, Jupiter 10, Mars 8, the Sun 17, Venus 8, Mercury 8, the Moon 12...Suppose the Sun is approaching the conjunction of Mars, you add their two orbs together, which is 25, and divide by two which is 12 and a half; therefore, when the Sun gets within 12 and a half degrees of Mars, the effects of the Sun conjunct Mars commence. It is the same with the other planets."

He did not explain specifically why he had decided to allocate 8 degrees to Uranus as opposed to any other number of degrees. (11)

In Raphael's book The Key and Guide to Astrology, where the Preface was signed by one Edwin Raphael [sic], he had abandoned the foregoing method and accepted Leo's theory while adding a few additions of his own. "The orbs of Uranus, Saturn, Jupiter, Mars, Venus and Mercury, when applying are about 6 degrees, and when separating from an aspect, they may be reckoned as 8 degrees.

The Sun and Moon have larger orbs. You may reckon the Sun when applying as 12 degrees and when separating as 17 degrees; and the Moon 8 degrees when applying and 12 degrees when separating from an aspect. These orbs apply only to the following aspects viz., the conjunction, sextile, square, trine and opposition.

The minor aspects viz., the semi-sextile, quintile and bi-quintile I consider only when the planets are within 2 degrees applying, and 3 degrees separating.

The semi-square, and sesquiquadrate are to be reckoned 3 degrees when applying, and 4 degrees when separating, that is, with the planets; the Sun and Moon may be allowed an extra 1 degree.

With respect to the parallel, I do not allow more than 2 degrees either way." (12)

It would appear therefore that Raphael was the first to suggest that applying and separating aspects could have different orbs, and that separating aspects are more powerful than applying ones.

Sepharial wrote that "Planets are called "in aspect" to one another when, at birth, they are found to be within 5 degrees of any of the distances indicated in the list of aspects". (13)

In his book Elementary Astrology, undated, he gave the following orbs for the planets. "The Sun, 15 degrees, the Moon 12, Jupiter, 10, Saturn, 9, Venus 8, Mars 7 and Mercury, Uranus and Neptune, 5 degrees each". (14)

It would seem therefore that Sepharial as well as Raphael had succumbed to Leo's influence and adopted the theory that aspects had orbs, and even though he was familiar with the traditional method, he eventually rejected it.

CONCLUSION

Leo's influence concerning the orbs of aspects has been a powerful one which has spread throughout western astrology. He never at any time gave a clear explanation as to how he had arrived at this concept or how it really worked, since he continually changed and never settled on one set of orbs for the aspects.

The modern practise of tightening the orbs is well meaning but mistaken, since it is thought that narrower orbs will pinpoint the aspects more accurately. This practice tends to remove important aspects simply because their orbs are considered to be too wide by modern standards. Yet these so-called wider aspects which were used by astrologers for a thousand years before the end of the 19th century, would clarify the natal horoscope much more if they were included. Only by using the orbs of planets as specified by Al Biruni and others throughout history can the meaning of the horoscope and its potential become more accessible.

There is a strong case for recommending that Irish astrologers, as well as those of other countries, make an in-depth study of their own astrological history in order to avoid any confusing influences from outside. To discover their own truths for themselves and cease to rely unthinkingly on the unfounded opinions of others. Eventually discovering that there is a common golden thread going through all of our histories, assisting everyone to seek the truth.

This article was written to demonstrate that the so-called modernisation of astrology undertaken in regard to orbs by Alan Leo, was ill conceived and inaccurate. Having shown through the history of these changes that confusion now reigns in this area of astrology, isn't it now time to revert to the correct and fitting method of designating orbs to planets, and to banish the illusion that aspects have orbs of influence?

A number of years later a friend presented me with further evidence that Alan Leo had been discussing the orbs of aspects as early as March 1892.  Here is what he wrote:

"The following are the orbs of the planets, as given by Pearce in the Science of the Stars. The Sun 17, Moon 12, Mercury 7, Venus 8, Mars 7, Jupiter 12, Saturn 9, Uranus 5, Neptune probably about 5. When two planets are approaching conjunction or opposition, add the orbs of the two together, and then take half the sum. This will give the distance at which the two planets will begin to influence one another. For instance, if the Moon is approaching the conjunction of Venus, as soon as the two are within ten degrees of each other, the influence of the conjunction will commence.

There are many astrologers who express themselves as dissatisfied with these orbs, and advocate a uniform distance of about five degrees for each planet. I do not profess to know for certain where the truth lies, but my opinion is that the orbs vary considerably for each aspect. The strongest aspects are undoubtedly the conjunction and opposition, and here, I think, the orbs which are given above are not much too large; but the margin of distance must be diminished for all the other aspects according to their strength.

For the square and trine, I would allow about three-quarters of the usual orb.

For the sextile, semi-square, and sesquiquadrate, I would allow from one half to two-thirds the orb.

The remaining aspects, semi-sextile, quintile, bi-quintile, and those others which are doubtful, I think, have no influence unless they are within one degree of being exact.

Some such arrangement as this appears to me to be more in accordance with reason than the rule of allowing a fixed orb, long or short, for every aspect, whether strong or weak, indifferently.

In addition to these considerations, it must not be forgotten that the nearer an aspect is to being exact, the stronger it is. For instance, an opposition or conjunction which is only just within orbs is probably of less importance than a square or trine which is exact in measurement; although the first two aspects are, speaking generally, stronger than the last two; and a semi-square or sextile which is exact has probably greater strength than a square or a trine, which is only just within orbs. The remaining aspects are not worthy of consideration unless they are exact.

Therefore, when considering a horoscope, let the student pay most attention to those aspects that happen to be exact in measurement, for it is tolerably certain that these will be prominent in the life history.

I think that two planets which happen to be in the same sign of the zodiac have some slight significance on this account, whether they are in conjunction or not.

There is doubtless much yet to learn respecting the precise signification of the different aspects, and why one is good and another evil.
