Quindecile is the 24 degree aspect, but the name has been wrongly given to the 165 degree aspect which makes no sense. 165 degree is the 11/24 aspect. Naming a 24th harmonic aspect the Quindecile makes no sense at all. The 24 degree aspect is the 1/15 harmonic aspect, and so naming it Quindecile makes a lot of sense. Quindecile is referring to 15th Harmonic and not 15 degrees just like the Novile is referring to 9th Harmonic and not 90 degrees. Quindecim is Latin for 15.
There has to be some logic in Astrology.
24 degree aspect was already named the Quindecile before Noel Tyl even wrote books.
Johannes Kepler is thought to have invented the minor 15th harmonic aspects just like he invented the 5th harmonic aspects which are the Quintile and BiQuintile.
The Trine and the 5th harmonic aspects are also 15th harmonic aspects if the orbs are small as 15th harmonic aspects.
Not all astrologers agree with Noel Tyl in labeling the 165 degree aspect. Some astrologers refer to it as Johndro. Some other astrologers refer to it as Contraquindecile.
