Fixed star Algol, Beta Persei, is a 2.1 magnitude, rare triple star and eclipsing binary, located in the Medusa’s Head, carried in the left hand of the Hero, Perseus Constellation. The name Algol comes from the Arabic word رئيس الغول, meaning  Head of the Ogre. The English translation became Demon Star, with other names being Satan’s Head, the Spectre’s Head. In Chinese it belongs to s group of stars called the Mausoleum. Algol it appears to blink as shown in the animation below.

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 star 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 star , 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. [6]

Algol star 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 Astrology

Perseus Constellation gives an intelligent, strong, bold and adventurous nature, but a tendency to lying. [3] The constellation is indicative of events affecting large numbers of people, especially those events caused by major meteorological phenomena. [5]

[3] Megan Fox 0°56′

Moon conjunct Algol: Violent death or extreme sickness. [3] Mick Jagger 1°24′

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]

Algol Star 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.

  1. Checking out Stephen Paddock’s chart there is Jupiter conjunct mars conjunct pars fortune on Algol with his natal Pluto in Leo square these planets. Algol was triggered in square to Pluto when the total eclipse occurred in August 2017. Paddocks chart shows a man prone to violence, selfish, and contentious. Again, Algol is triggered causing mass murder with this total eclipse and this evil man’s chart should be studied including the stars.

  2. Get this. My 8th house Sun is in 26 degrees of Taurus. As if that’s not enough, the cusp of my 8th house is also in the same degree of Taurus, 26 degrees. Apparently, that’s not so good, ? My 8th house Sun is also squared by Pluto in the 10th house.

    Any comments ?
    I’ve noticed the person who made the page doesn’t reply to comments. Why not ?

    • I do reply to comments just not all of them. I don’t have the time with writing free weekly, monthly and yearly horoscopes, moon phases, aspects and transits, then fitting in personal readings and raising three kids on my own and in and out of hospital.

      • hi,
        OK, thanks. I saw the question from 2017 further up the page unanswered and assumed it went unanswered because you just don’t, since it was from last year. Good luck with the hospital.

        • Usually other people answer questions too but we are all really beginners with fixed stars. That’s why I wanted to write these pages so the comments would add more detail. Eventually I want to add more celebrities to the fixed star conjunctions which would be very helpful.

          • Oh that explains a lot. I assumed you were an expert !
            Yes, famous people’s charts help illustrate. I used to have Lois Rodden’s Astrodata bank, still do but not uploaded anymore but I have the disc. It was fascinating.

          • I noticed that dancer Isadora Duncan had a fixed grand cross involving Pluto on Algol, Mars-Lilith, the Moon and Uranus. She was strangled by her long scarf when it was caught in the wheels of a convertible. I’ve also been wondering about the latest spate of celebrity hangings (Bourdain’s passing really broke my heart). As Algol was so active as Uranus ingressed into Taurus, it makes me wonder if we’ve heard the end of these high profile hangings.

  4. Hi Jamie, If you have time, was hoping you could tell me the significance of Algol conjunct Neptune in the 10th house.

    Love your site!!!

    Thanks in advance, Margaret

    • Not a substitute for what Jamie can tell you, but here’s a little historical background:

      The last Neptune–Algol conjunction occurred in roughly 1885–1887 (Algol was at around 24°32 Taurus back then).

      I’d have a look at what was happening in the world then, as well as at the bios of people born in those years, especially around the exact conjunctions in June and September 1885 and April 1886.

      In a cursory search, I was struck by the number of prominent authors born around the 1885 conjunctions whose works are still widely read in the present era, including D.H. Lawrence, Ezra Pound, Sinclair Lewis, Karen Blixen (Isak Dinesen), and Edna Ferber. A glance at their lives might help provide some context.

      The 1886 group also contained a few authors and composers but had a broader representation from the fields of architecture, science, philosophy, astrology, theology: Ludwig Mies van der Rohe (architect), Louis Pasteur Vallery-Radot (physician & his famous grandfather’s biographer & editor), Frederick Lindemann (physicist), Karl Barth (theologian), Ellen McCaffery (astrologer), Jean Verdier (engineer-author-astrologer), Geoffrey Hodson (theosophist). Soldiers who went on to become writers and influential thinkers were also a recurring theme in the latter group.

    • I don’t use House only Ascendant axis and Midheaven axis. But Algol with Neptune would be good for creative talents like music and dance I would think. But it would make you very sensitive when you see bad things on the TV news like disasters that affect lots of people.

  5. Thanks for taking the time to respond and keep up the great work. Love your site and best regards!

  6. Very interesting, thank you. I never considered where this star was and just took the time to research it. Apparently I have Algol at 25 deg. Taurus. Therefore it is a return I believe. Any thoughts Jamie?

  7. Oh Jamie!
    I did my solar return over the weekend and was gob-smacked to see that Algol is on my MC! Orb 0:57.
    In my natal chart, Algol is on my Desc, orb 0:19, and the baleful star seems to have been following me around lately in that it appears in a prominent position in most of the charts I calculate for progressions or transits to my chart. A few months ago I was quite ill, and Algol was on something or the other when the illness started.
    But there’s more.
    I ran my son’s solar return, which will occur in December (mine happened in the last few days). He has Algol on HIS MC, too, with a tight orb. His natal Algol is right on his Asc. – We were born in opposite hemispheres, it occurs to me.
    Not only do our Algols match in the solar returns, every single house cusp matches as well, within a degree or two of orb.
    What can possibly be going on?
    I must say that I’m not really scared of Algol. I’m pretty much accustomed to his energy after all this time. But I AM wary. Your interpretation on this page says “murder, sudden death”. We DO live in quite a volatile country…

    • hi Char !
      Try having your natal TAURUS SUN in 26 degrees inside the 8th house,!
      plus the 8th house natal CUSP in the same 26 degrees, like the 8th house Taurus Sun !
      That’s what I’ve got ! Augghhh !

      I wanted clarity too, but from what I’ve understood here, everyone’s learning, no one is an expert
      on it so, yeah,
      I hope someone can explain it to you though, if they do maybe they could give their 2 cents about
      my natal Algol ! I sure have a ton of it for my Sun and 8th house. Freaky !

  8. Jamie, I was looking at the Star Trek chart, Sep 6, 1966, 8pm Halifax, NS…. and Algol is Sextile Jupiter in a Yod with the Galactic Centre. The GC is at the top of the chart conjunct the Mid Heaven. The Yod looks like the Arrowhead insignia from the tv show and NASA symbology …. could it be?

  9. I weeks I understood all of this…I feel like I’m reading a different language that I don’t speak…sucks because it seems do intetesting

  10. Well… I know someone who has both the Sun and Mars conjunct Algol. Of course never say never, but he is 67 now and is one of the luckiest people I know, on all fronts.
    If I am not mistaken, Pope John Paul II also had the Sun conjunct Algol. While he was sick towards the end of his life, it would be a gross exaggeration to call it “extreme sickness” – or violent death, for that matter.

    • Perhaps he had a great deal of benefic aspects and placements. Maybe lots of Jupiter.
