Aculeus Star Astrology

Fixed star Aculeus is of the nature of Mars and the Moon. It effects the eyesight and causes blindness of one or both eyes if in conjunction with an afflicted luminary, or in conjunction with a malefic that afflicts the luminaries. The opposition seems to be equally effective. [1]

Aculeus (M6) and Acumen (M7) are multiple clusters, not single stars. They are of immense size, as comparable to galaxies as to stars, but very far distant and very faint, when visible at all to the naked eye. Ptolemy listed them both as Mars-Moon stars, probably unaware that they were clusters, and both names echo Lesath, meaning Sting.

Both have a notorious reputation in astrology as ‘Blind Stars’ and are said to inflict blindness for certain on the one unlucky in having them prominent on the horoscope. Leaving aside the suggestion that any star ‘ inflicts’ anything at all, yes, the author has found that people with these and/or other ‘ blind stars’  prominent do have eyesight problems, but then so has he, and he does not have them prominent on his own chart.

But he has noted a number of cases of clients asking his advise about forthcoming eye treatment, especially operations, and showing excessive worry about the outcome, unaware that one or other of these stars really was going to be strong on their charts on the date in question. it does no harm at all then to advise the client to seek another date, or a second medical opinion, if only because their nervousness may communicate itself to the surgeon and actually precipitate and error in that way. Beyond that, one must allow that the presence of the stars upon the event may indeed be a sign that the client has indeed pre monitored an unfortunate outcome, by whatever mode of intuition may be working within him or her.

Apart from that ominous portent, these two star clusters do show up a negative Mars-Moon quality in people who have them poorly aspected, with a tendency towards a morbid outlook, seeing the worst rather than the best in everything. If their religious views are affected, as so often with anything in Sagittarius, there is a tendency to be either the ‘hellfire and damnation brigade’ or to take up a fierce anti-religious and even anti-God stance. But at their best, well aspected, they can have very sharp minds and a perception well above average as though, perhaps ‘blind’ to what we see and take for granted, they see what we do not, at levels where eyesight does not reach. Not for nothing has the word Acumen come down to us as a term for a sharp mind. [3]

Aculeus rules the left side of the groin in the human body. [4]

Constellation Scorpio was the dreaded symbol of darkness in the region of the Euphrates. Comets in this region of the sky were said to portend plagues of “reptiles” (read as locusts or other insects harmful to agriculture). In Classical Scientific Astrology the fruitful nature of Scorpio was mentioned. This attribute also applies to the constellation. The constellation of the Scorpion has been considered unlucky from earliest antiquity. [2]

Aculeus Star Conjunctions

Mars conjunct Aculeus: This position affects the health. It causes hemorrhaging through wear on the blood vessels, with the result that the groin area becomes clogged. It will manifest as a slight aching and a slight weakness. Golden Seal Root will strengthen the tissue around the groin when taken in small amounts, ¼ cup three times per week and alternating every other week. [4]

Pluto conjunct Aculeus: Many will be born with this configuration and all will have weakness in the hip area. It will not be understood as to why so many individuals have have the same problem. This causes a decided weakness in the tendons so that they have a difficult time with complete mobility of the left leg. This becomes more serious as the individual ages. Their diet should include green lima beans, green peas and broccoli. These three vegetables will greatly help to strengthen the tendons. They should not exercise this area until the strength returns.
