in an astrology course I'm doing I was told that both these rare aspects signify unsual or uncommon talent or even genius.

I don't know if this is true or not though. It's not a common aspect.

If there were a 'Grand Quintile' (??) then I'd assume it would take the form of the pentagram. I case it would depend on what planets and houses are involved. The pentagram as you've said, depicts mastery over the four elements, or conversely the elements mastering us.

hrmm i have jupiter-neptune and venus-mars quintiles. not sure of what to make of it, but ive observed them a little when looking at my transits and i do think i can feel a positive effect from them.

Johannes Kepler devised the quintile and biquintile which are both 5th harmonic aspects.
I have Mercury biquintile Eris with 6 minutes of arc,and I feel that indicates my creative,lateral,outside the box,multidimensional thinking that fits with the strengths of Dyslexia,Dyspraxia,and ADHD which I do have and helps me a very good astrologer. I also feel indicates my advocacy and communicating about equal/civil rights.

I have Sun biquintile Midheaven with 5 minutes of arc,and I feel that indicates that creative self expression being noticed

I will give you a little information,and you don't have to read it. I am not trying to be preachy or anything else like that. I am very Neptunian,and so I am very hard to pin down and get misunderstood a lot like my Dyslexia,Dyspraxia,ADHD does...neurodivergent people are very hard to pin down people and get misunderstood a lot any way.

The quintile and biquintile have deep origins.

Astronomer/Astrologer Johannes Kepler devised the quintile and biquintile.

His early work had attempted to explain aspects by relating them to three-dimensional solids but this didn't really get very far. His later work derives more completely from musical intervals. He explains the five aspects Ptolemy used and the three new ones of his own by taking various fractional lengths of a string, as with violin string, and looking at which rations give pleasing harmonics and which do not; but even this doesn't work perfectly and he spends a lot of time looking at two-dimensional plane figures and their degrees of symmetry. As a mathematician, he discovers a couple of new such combinations - 'tessellations' or regular figures that lock into each other on a plane surface, and he uses the angles which they form to explain which harmonics are astrologically important and which are not. So, there are a lot of diagrams in his work showing regular figures in terms of the angle made against the zodiac. He asserted that "No more than 8 harmonic ratios arise from comparing the regular plane figures", adding that he hoped one day to be able to demonstrate this. These give him the eight aspects of conjunction, opposition (1:1), trine (1:2), square (1:3), quintile (1:4), biquintile (2:3), sextile (1:5) and sesquiquadrate (5:8). So there is a big difference between Kepler's approach to harmonics and that which the late John Addey developed:[12] Kepler seeks to show there are only a limited number of aspects that actually work in astrological terms.

From HOROSCOPE SYMBOLS by Robert Hand
THE FIVE SERIES----Quintile,Biquintile,Decile

Quality similar to that associated with Pluto, with overtones of Venus and Mars: some kind of concrete creation or destruction is effected. Intellectual functions (not excluding emotion) and all especially human matters. Transformational change. The ability to express creative inspiration (due to other factors) in concrete creations.


John Addey says that Five represents the putting together of form and matter and in this sense, art.

HARMONIC CHARTS A New Dimension in Astrology
David Hamblin's own research has convinced him that Fiveness is essentially connected with the idea of making,arranging,building,constructing,structuring,and forming. He says that it has to do with the creation of order out of chaos: the bringing together of things that are naturally separate into a formal relationship with one another. It is therefore,the first number in which man asserts his power over the the wrold. Within the principle of Twoness,he accepts the world as it is and struggles to find his place in it;within the principle of Threeness,he accepts the world as it is and revels within it;but within the principle of Fiveness, he strives to change the world and to make other than how he found it.


Adze's classroom
Quintiles are measured from plus or minus seventy-two degrees. Bi- quintiles are measured from plus or minus one hundred and forty four degrees which is one or two fifths of a circle. When planets are quintile or bi-quintile this is an indication of uncommon creative energy and talent. They are trend-setters and need an audience. The energy here is specialized and purposely striving toward power. Quintile and bi-quintile energy can be romantic, playful and demonstrative. The quintile family of aspects can indicate science, math and engineering. There's a need to make things happen. Cosmic will seems to be at play here, so if creative things aren't happening, then look for destruction. Quintiles and bi-quintiles bring a certain dignity, clarity, pride and unusual sexual energy. A quintile resonates with the Sun, Fixed, Fire and Leo energy.

I'd like to find out more about these... I've got Sun/Uranus quintile Saturn (within 1 degree of each) and Mars quintile Pluto (5 minute orb). If anyone has thoughts or links, please share.

I have Pluto biquintile the Sun and N. Node...and Mars quintile the Sun.
I'm not one to ask for freebies, but...does anyone know of any interpretations for those aspects.
Just curious.

Peace, Bo

Wow, when I logged on there were on 72 responses!

To my huge surprise. Still 'dumbfounded', told you 'it was important'.
(Especially that it is not discussed in most literature.)

I'll print & examine thread, & try to cook up a proper response...

Love,

ML.

wow.
i haven't signed in for a week.
and look at all the responses for the Quintiles...

i think i would qualify for a case study for quintile research... although i can't find any actual pentagram shape in my chart... i have a number of quintiles, involving conjuncted planets Saturn and Pluto (12th house Libra), the Moon (3rd house Cap), Mercury (10th house Leo)... etc... i
haven't memorized them all but here's a link to the 5th Harmonic:
img33.picoodle.com/img/img3...9c13d.jpg

and a link to my natal chart (it'll show my quintile aspects):
www.picoodle.com/view.php

it'll be quite interesting to see what t-Pluto will do, once it quintiles its own footprint in my natal chart...
conjuncting the Moon, then quintile-ing Saturn/Pluto... bQ-ing Mercury, etc....
and then before it's all over, t-Saturn will return to its own post...... etc etc



now.... time to read all the posts above me....

As I logged in... 73 replies.

So, to rehash the 'nuggets':


The symbol of the Pentagram.
Points correspond as Spirit, Air, Fire, Earth, Water (from top, clockwise).
"Q" represents a "quintile" -- a minor harmonious aspect of 72 degrees.
"bQ" a "biquintile," aspect of 144 degrees, considered a minor harmonious aspect.
Q as 'elemental friendly', bQ as 'contrast'...
I'd say their orb are 'tight' 1-2 degs only.

usually no more than a 3 degree orb is used ... (ie, less than, 2 or 1 (or 0'))

"harmonic charts"~by david hamblin

...very difficult to analyze-pin down and all that.

minor aspects are very sublte and really have to be brought out...
they could very well lay dormant.


A 5th harmonic chart would resolve a quintile or biquintile into a conjunction.
It would show how the person defines what creativity is for the person,
what type of creative outlets the person has or will develop, how outside forces
have tried to shape the creative product, etc., through the aspects that
are made with the resolved quintile or biquitile.
