Garth Allen introduced the Ennead less than a year before his death, in the September 1973 issue of American Astrology. The salient points are as follows, under the title "Return Theory Updated":
- When the Solar Monthly Return was first introduced (Sun every 30° around the zodiac - same degree, minute, and second as at birth, but of each successive sign, once per month), Bradley investigated its possible merit. He tested it "statistically, using mainly death and accident cases." He found statistically significant results in favor of the SMR.
- However, the results were anomalous. The charts for Sun trine natal Sun (two of the non-SSR SMRs in the course of the year) were "surprisingly on the plus side, even more than the "square" returns, called the quartisolars."
- (It is no longer a surprise to me that the quarti-solars performed so poorly. I've given up on them, other than for the narrow purpose of determining the quarter of a year when primary SSR results will manifest. The key here is that, other than the SSR itself, the SMRs that were most strikingly significant were the two where Sun trined Sun.)
- Initially bothered by this, he soon realized "that the originally Egyptian, currently standard Hindu, system of 'novienic' or 'navamsa' divisions of the ecliptic also held true as viable returns." This meant "nine basic 'solar returns' during each year," one for every 40° of Sun's travel.
- He went on to show how often the Bible etc. spoke of life circumstances that lasted "40 days" or "40 days and 40 nights" - the average duration of an Ennead being just over 40 1/2 days (ranging from 38.3 to 41.9 days).
- "With the exception of the first or conjunction solar return, which applies to the full year ahead in general and the first 40 days after one's birthday in particular, each of the novienic solar returns holds sway over a period averaging just over 40 days and nights."
He cited an unnamed colleague's suggestion that this technique be called the Ennead ("eeny-add") with the quarters called "decilium" (or, as he said, "some such old-fangled title").Garth Allen wrote:I believe it can be stated quite unequivocally, on the basis of extensive statistics, that the novienic solar return is more intense in its impact than even the familiar lunar return. So lucid are its indications, we are tempted to suggest that the recent proliferation of "return" formulas - kinetics, anlunars, and all their cousins - amounts more to a search for the novienic return than to practical truth. What is more, there is evidence that the 40-day period breaks down into four "decanate" subintervals of 10 days apiece. It would be wise for each student to set up his "quarti-novienic" solar returns for major events in his past life, to see for himself if this approach is not more reliable than the saturation-bombing, using a profusion of intricate chartings, he has applied to his astro-biography.
