Algol Star Astrology

In astrology, Algol is one of the most unfortunate stars. Ptolemy referred to it as “the Gorgon of Perseus” and associated it with death by decapitation: mirroring the myth of the hero Perseus’ victory over the snake-headed Gorgon Medusa. Historically, it has received a strong association with violence across a wide variety of cultures. Medieval Arabic commanders tried to ensure that no important battle began whilst the light of Algol was weak. It may be connected to the periodic lucky prognosis in an ancient Egyptian calendar for lucky and unlucky days composed about 3200 years ago.The 17th century English astrologer William Lilly regarded any planet to be afflicted when within five degrees of conjunction. [1]

Astrologers of course said that it was the most unfortunate, violent, and dangerous star in the heavens, and it certainly has been one of the best observed, as the most noteworthy variable in the northern sky. [2]

Algol represents the head of the Gorgon Medusa who was slain by Perseus. Medusa, who was the only mortal one of the three Gorgon sisters, was originally a beautiful maiden, but her hair was changed into hissing serpents by Minerva in consequence of her having become by Neptune the mother of Chrysaor and Pegasus in one of Minerva’s temples. This gave her so fearful an appearance that everyone who looked at her was changed into stone.

Of the nature of Saturn and Jupiter. It causes misfortune, violence, decapitation, hanging, electrocution and mob violence, and gives a dogged and violent nature that causes death to the native or others. It is the most evil star in the heavens.

Algol symbol (Agripe 1531).svg  Algol is one of the 15 Behenian Fixed Stars. Its image is a human head cut off at the neck. It gives success to petitions, makes the wearer bold and magnanimous, preserves the body, protects against witchcraft, and turns evil and spells back upon those who work them. Rules diamond, black hellebore and mug-wort. [3]

Algol Star Astrology

Algol Star []

Algol is the Head of Gorgo Medusa. This name is derived from the Arabic Al Ghoul meaning “demon”, “evil spirit”, or “devil”. Derived from the same root is “alcohol.” The dark one has the property of pure Saturn character; the lighter one corresponds not only to Saturnian influence but also to Mars-Uranus-Pluto nature. If the dark fellow is showing toward Earth’s path, the destructive invisible action is exercised. These will be the hours in which Algol is least bright. In the olden times, people were well aware of this. Dr, Lomer wrote in Kosmobiologie, August 1950: “Arabic commanders-in-chief, in times of conquest, made it a point that no important battles were begun when the light of Algol was weak.”

In spite of the appreciable distance from the ecliptic, this double star’s influence is strongly felt and in more cases it is a disastrous one. Primitive natives will be of the base mind with an inclination to brutality and violence, especially when Algol is found together with Mars or Saturn. It is very difficult to avoid accidents and severe injuries if Algol is conjunction Sun, Moon or the malefics. As everything has two sides, it has to be said that “high spiritual rays” are emanating from Algol also, but only those human beings can receive them who have already reached high spiritual development. Even then, it has to be noted that those particular persons will have difficulties and obstacles in their way, and they have to use much energy to overcome these handicaps. If their endeavors fail, strong counter forces and enmities will be present. [4]

Algol has the nature of Jupiter, but it also has a long tradition as a trouble maker. It is said to be on of the most unfortunate, violent, and dangerous stars in the heavens. This is explained by the fact that Jupiter takes on all of its most perverse meanings: too much heat, as it were, resulting in extremist actions that undo all the beneficial qualities of this planet. [5]

Algol, alias Caput Medusa, is the Demon herself. Indeed she is without doubt counted the most malefic of all stars in astrology, even though Ptolemy gives her the less obviously ominous Saturn-Jupiter styling. Medusa’s Head, the meaning of the Latin title, is being held in Perseus’s hand, which is she is star β in his constellation.

What seems to have been missed by the old school is that Capulus and Algol each have a very positive side to them. The sword did remove a monstrosity from our world, and the monstrosity’s head did, in its turn, rescue Andromeda – and by the same token, all of us – from yet another monster of great evil. True that Algol comes from an old Arabic word meaning particularly nasty spirit but then, as we have noted, we all too easily look back and within ourselves only to be halted at our traumas and ‘nasty bits’, failing to penetrate further to the glory beyond them. Lilith is not Medusa at all, not the ugly blockage in us but the beauty beyond it. Once we pass the ‘ghoul’ in Algol, we find the pure Spirit in that word, just as its modern derivative, Alcohol, which does so much damage if used irresponsibly, is also the background material of the Universe, without which nothing else exists at all.

How Capulus, and more especially Algol, signify on horoscopes depends entirely on how the person concerned does or does not live life with an honest sense of purpose to it, a desire at least to try to live up to some kind of philosophy, religion or ideal. If that be present, in the person or question or event for which the chart is drawn, then all will go well. The author has seen this happen so often, once the superstition about these stars is dropped. If purpose and intent be ‘shady’, then we don’t really need stars to tell us that things are likely, with good reason, to go wrong.

Yes, we know that Algol often does show up in disastrous accidents with death as their climax, but we must remember that our too-common state of disbelief in life beyond the one event since birth that is the lot of all of us. We fear because we do not believe, and we fear to overcome our fear, lest to be fearless of death should somehow cause us to love mortal life the less. We fear to let go of the past because we lack faith in the Hand that holds the future. With Algol poorly aspected in our charts we may well repeat the popular but obscene: ‘Better the devil you know that the devil you don’t’ , but those with the Star of the Spirit better placed, we find the person who knows better than to slander the Hand as a devil. May a fine counselor and healer has Algol thus placed.

Alcyone, η Tauri, and the whole Pleiades group, is noted in astrology for its association with deep sorrows and tragedies, bereavements showing strongly with this star. Its position by longitude soon after Algol in Perseus may account for the gloomy quality, since Algol is much connotative with violent death in mundane astrology, and that of course means bereavement for someone else. As a practicing astrological consultant, however, the present author has found that one or both of these stars prominent, even though ‘afflicted’, on one’s horoscope makes for an excellent counselor to others in the time of bereavement, with a special gift for bring out the brighter spiritual significance of Death as the transition to Greater Life and this so very often relieves the counselor him or herself from the misery that others so commonly suffer in that area of life.

Algol rules one-quarter inch up the base of the neck in the human body. [7]

I have found that a strong Algol placement in the natal chart corresponds to very distinctive facial features and hair. There may be a striking beard or glorious long hair. The teeth, nose or ears may also be striking in some way, either extremely beautiful, large or deformed.

Constellation Perseus is like Jupiter and Saturn. It is said to give an intelligent, strong, bold and adventurous nature, but a tendency to lying. [3] The constellation is indicative of events effecting large numbers of people, especially those events caused by major meteorological phenomena. When prominent in a natal chart it is said to denote adventurous individuals, but also those who are less than honest in their dealings with others. [5]

Algol Star Conjunctions

Ascendant conjunct Algol: Linda Marshall 0°28′ plus Uranus.

Midheaven conjunct Algol: Murder, sudden death, beheading, prone to murder and mischief. If at the same time in conjunction with Sun, Moon or Jupiter, gives victory over others in war. [3] Donald Trump 1°03′.

Hyleg conjunct Algol and angular: decapitation or a murderer who meets with a violent death. [3]

Part of Fortune conjunct Algol: poverty. [3]

Sun conjunct Algol: Violent death or extreme sickness. If also in no aspect to a benefic, or there is no benefic in the 8th house, and the dispositor of the Sun in a day nativity or if the Moon in the night one is in square or opposition to Mars, the native will be beheaded; if the luminary culminate he will be maimed, mangled, wounded or torn to pieces alive; and if Mars is at the same time in Gemini or Pisces his hands or feet will be cut off. [3]

Moon conjunct Algol: Violent death or extreme sickness. [3]

Moon conjunct Venus conjunct Algol opposite Neptune: This energy point causes a multitude of problems connected with the neck. These people are unable to look down to see their feet, and when under stress, are unable to bend the neck forward or in any direction. Their energy is blocked up to the pituitary gland thus interfering with spiritual development. A great deal of the problem here is the lack of spiritual development as these individuals wish to remain fixed on the mundane and material areas of their life. These beings should consult spiritual healers who can make life a bit more comfortable for them as it will help open up the energy at this point and balance it with the rest of the system. Other parts of the body can be affected here, especially the thymus gland which in turn affects the lymph nodes. Contrary to popular belief, the thymus gland does not discontinue functioning after puberty; it does continue to function and affect the lymph nodes and spiritual development. [7]

Mars conjunct Algol: or if Mars be elevated above the luminaries when Algol is angular, the native will be a murderer who will come to an untimely end. The same is caused by Algol angular or with the hyleg. [3]

Mars or Saturn conjunct Algol and Moon with Sadalmelik: hanging or decapitation by royal command; if the Moon is with Denebola death by judicial sentence; and, if the Moon is with Alfard death by water or poison. [3]

Jupiter conjunct Algol: This is the best placement for Algol. It gives wonderful creative talents such as music, from which one can make a good living.

Uranus conjunct Algol: Linda Marshall 0°25′ plus Ascendant.

North Node conjunct Algol: Hillary Clinton 1°52′.

Algol and Evolution

From the mythology of Medusa we can see her as a mutant. As mutation is the driver of generic evolution, it is no surprise to see the Algol star prominent in the history of the Human Genome Project.

On June 1 1866, Charles Benedict, the father of the American eugenics movement was born. Mercury was conjunct Algol. He sterilized 60 000 “unfit”, or mutant Americans and “strongly influenced the Holocaust in Europe” [8].

On July 16 1945 we exploded the first nuclear bomb, the Trinity Test in Nevada. Mars was conjunct Algol. The bombings of Hiroshima and Nagasaki that followed killed over 200 000 people and mutated countless more.

On April 25 1953, Watson and Crick published their groundbreaking discovery on the structure of DNA, the building block of our genes. Jupiter was conjunct Algol.

On December 9 1984, research on casualties at Hiroshima and Nagasaki led to the Alta Summit, the beginnings of the Human Genome Project. North Node was conjunct Algol. “If genome projects prove important to biology, then historians will note the Alta meeting” [9].

On June 25 2000, president Clinton announced the completion of the Human Genome Project [10]. Saturn was conjunct Algol.

On May 18 2006, the sequence of the last chromosome was published in the journal Nature. Sun and Mercury were conjunct Algol.

On May 21 2008, the Genetic Information Nondiscrimination Act became law “To prohibit discrimination on the basis of genetic information with respect to health insurance and employment” [11]. Venus was conjunct Algol.

40 thoughts on “Algol Star – The Blinking Demon

  1. I have 26 degrees of Taurus on my 8th house cusp. My Sun is in the 8th house and is also in 26 degrees of Taurus. Pluto squares my Sun from the 10th house. I’m not sure where Algol itself is in my chasrt.

    As far as hair….I’ve never had short hair in my life, except when I was a little child and had no say in the matter.

  2. I would think it would be meaningful only if you have a planet (especially a luminary or personal planet) or point conjunct Algol. I have Moon(0°)/Juno(0°)/Saturn(5°) conjunct and Algol aspects every planet in my chart except Jupiter (which, however, is conjunct asteroid Medusa). I definitely feel it in the trine (to Mars/Pluto) and sesquiquadrate (to Uranus), but I think that’s mostly because of the Algol Moon.

  3. just a note: Not sure if Algol conjunct one’s node pertains. Example: Albert Einstein had Algol conjunct his North node and surely he was a good man. But when he died, his head was cut off so that the scientist could examine his brain. This was not Albert’s request as he wanted to be cremated. So it seems Algol reacts even upon death.

    • Great information Thank you Judith. People aare always asking about the lunar nodes with fixed stars. This is one more piece of excellent qualitative evidence in support.
