In 1963, Garth Allen wrote:
Nearly a dozen years later, he finally was willing to commit to paper the notes that follow, but only privately. (He wrote them down at the insistence of Gary Duncan, who gave them to me.) The task of confirming "Sidereal gospel" (if ever there is to be such a thing) was left in the hands of those who come after. I thought - as both raw material for further research and historical value - I should make this entire set of notes public....the job of untangling the mess (and our own minds as well) from the habit of tropical zodiac preconceptions is far from complete. Even after more than a dozen years divorced from tropical horoscopy, we personally have a dickens of a time freeing our minds from the coloration of stereotypes carried over from our earlier career in tropical astrology. The so-call stubbornness of Taurus or sexiness of Scorpio or fickleness of Gemini were so strongly entrenched in our concepts early in the astrology-learning game that such singsong catch words still intrude on our thinking processes when we endeavor to visualize the parade of "zodiacal types."
...What follows is pure opinion, not sidereal gospel. The sidereal gospel won't be written for many years to come, apparently, and when it is, it may read much differently from what our pens can produce now.
ADDENDUM 2022: Today we probably would refer to devoted Taurus playful & pluralist Gemini, imaginative Cancer, stately Leo, analytical Virgo, enticing (or seductive) Libra, volcanic Scorpio, rank & rightness Sagittarius, discontented Capricorn, eccentric Aquarius, romantic Pisces, and contrary Aries as general expressions or principles.
