We were away for a month teaching, so I didn't have too much time to write; however, upon my return, I decided to re-visit a short essay that I had written on this topic that I had hoped would be included in Acutonics textbook, From Galaxies to Cells: Planetary Science, Harmony and Medicine, of which I am a co-author. Regrettably, when the time came to publish the book, anything remotely smacking of astrology was excised. This was a great source of disappointment to me, and one of the many contributing factors that caused me to leave that community. That being said, I am expending on the previous writing, and including information on Holst's temperament (there is an interesting parallel to Renaissance magus and priest Marsilio Ficino), and I think it will be quite a good piece when it is done.
