I find it helpful to think of the aspects as they relate to the starting point of 0Aries, the I am. The semisquare is the 15Taurus, the Sun's home when Beltain was celebrated. It was a festival that celebrated the fertility of spring with a phallic symbol at it's heart. It was the promise of the coming manifestation of what Aries wills. The problem is, its only the promise, the seed lying within the dark earth, not yet germinated or having gone through gestation. It hasn't yet had the thought or found the Holy Word to bring forth his promised creation (sextile) and is at the midpoint of the full blown obstacle where he discovers certain things just don't work together in certain ways. The maidens dance around the phallic pole, dressing it with ribbons in hopes that they will be blessed with the right knowledge (Gemin) and fertile womb (Cancer) to bring forth Aries' fruit. If the winter was too severe, the winter wheat planted in fall may have been damaged, endangering the first harvest of the season. That is why the semisquare can often indicate health problems, the result of frustrated being (Aries).
The sesquisquare represents Lammas, the offering of the first fruits when the Sun transits 15Leo. This is the time when the first fruits have a chance to ripen if they are fortunate and blessed enough to have enough water during the time of the scorching Sun, and the wheat wintered over well. If there were severe freezes with little snow cover to protect or it has been a drought, the time of greatest harvest is in danger. So the maidens weave dolls out of the winter wheat that rippened as offering to appease the gods in hopes that the greater harvest will be abundant enough to get them through another winter. Here the seeds for the 6th house health problems can begin. At the trine we are given an opportunity to will what we desire. If we are lacking any of the details necessary for love and true pleasure, if we fail to re-create, the sesquisquare will take its toll. If the frustration continues without finding the magic cure we continue on the the festival of Samhain where we give offerings to the dead hoping within that death there is a fertile germ cell to bring new life, to return or replace what was missing or lost, perhaps seeing what was needed for that bountiful harvest. Finally, in midwinter at Imbolc, after Persephone has been transformed by Hades we celebrate the impregnated seed, deep within the earth, invoking its journey to the upperworld to fulfill the promise of new life.
Kepler followed the harmonics of music. He said"
The quintile is equivalent to an interval of a major third (4:5), ex: musical notes C & E. This is beautiful harmony such as the soprano and alto duet. This would be 0Aries singing with 12 Gemini and would provide the talent (information) necessary to manifest in Taurus or give pleasure and recreation in Leo.
The biquintile to a major sixth (3:5), ex: C & A. The biquintile sounds quite harmonious and would be followed beautifully by the quintile. I feels just like the number, 144, 12x12, a full gross. All you need to meet the requirements for the best price so you can resell it for a profit. They say its like a double talent. Perhaps it is a compound talent or the ability to synthesize two differnt skills into something unique. Perhaps it is the ability to multiply the value enough so that you sill have something left over to repeat the process again. When I hear the major 6th my imagination simply flows into a major 5th (C & G)
Both 72 and 144 reduce to a 9, the last single digit, the number of the Sun. The amazing thing about the number 9 is that no matter how much you multiply it, it always reduces to 9, what you started with remains constant. I put some quarters in a machine once to kill time while my husband gambled at a casino for the first time. Unfortunately he lost but for a $3 investment of the 36 (I think) we began with, I won $444 which kept him playing over 2 hours. 444-3=441=9, again a multiple of 9 reducing to what it started with. And we went home with the same amount we started with. I have Pluto at the 144th degree, that is the reverse of 441. Hmmm
The sesquiquadrate to a minor sixth (5:8), ex: C & A flat. When I hear those notes together, I want to drop the A flat down to G in order to resolve the tension. To hear those notes alone leaves me feeling incomplete, dissatisfied, like I over reached, almost made it but what I wanted wasn't possible.
My ex husband has his Moon with a degree of here. The above feelings were realized at the end of our 28 years together. I admitted defeat and allowed divorce into my vocabulary.
Aparantly these are the only 3 that Kepler would use. Lilly added the semisextile, etc.
Here are a couple articles about Kepler.
