Princeps Star Astrology

Fixed star Princeps gives a keen, studious and profound mind with the ability for research. It is like Mercury and Saturn (subtle, studious, keen and profound mind, often shameless liar, interested in occult or serious subjects.) [1]

Princeps is another marker of our capacity to protect and be protected, but with a good hint of our role as Regent princes, and of the Crown that is ours for doing the job well. [2]

Princeps rules four inches below the navel. [3]

Constellation Boötes

Bootes gives prosperity from work, strong desires, a tendency to excess, a fondness for rural pursuits, together with some liking for occultism. [1]

14th Arabic Manzil – Al Simak

Causes marital love, cures the sick, helps sailors but hinders journeys by land.

With Moon: Dig but do not marry or travel.

Ist Chinese Xiù – 角 (Jiǎo) Horn

Excellent for construction or buying land. It represents agriculture, new generations, growth, and births. All who marry on this day gain great credit and standing and especially favors the marriage of the eldest son of the family.

Calamities and epidemics in the family within three years if funerals are planned on this day. If the Moon occults Spica at a key event, one should hold grave fears.

Mercury conjunct Princeps (1°00′ orb): These persons have an extremely keen and sensitive response to everything around them. They communicate on the extra-sensory level, and have those “gut” feelings that dominate their existence. They never make a mistake when following their feelings, and are usually in touch with these feelings even though they do not realize it. They can perceive and judge situations quickly when it is necessary to do so. No matter what information they wish to obtain, they know just how to locate the information they need. The one drawback here is that they are unable to explain just how they were able to get the information or material. It would do well for them to have a partner who can log exactly the method they used to obtain the information or material. These individuals would make excellent employees for research or investigation agencies, as they would enjoy that type of work. [3]

Venus conjunct Princeps: Bruce Lee 0°57′

Mars conjunct Princeps (0°30′ orb): This planet distorts the sexuality of the person. They can be over-sexed or under-sexed depending on what planets aspect this point. This can sometimes be quite destructive as they are very much obsessed with sex for the sake of sex. These persons use objects to excite themselves in many different ways, causing many injuries to themselves as they do not know when to stop. They are obsessed with the genital area even though they may not have an intimate relationship with anyone. This affects both men and women, and their obsession would bring difficulties with others who are close to them. This is a karmic position, for in a prior life, they abused others, and now they are abusing themselves. [3]

  1. Why am I not surprised, I was researching this Star, googled it and your page was on the top. Someday people will realize that the heavens influence our life. Take care Jamie, you are the best!!

  2. Venus conjunct princeps, opposite moon in Taurus conjunct sedna.

    Moon is the apex of a tight yod between Mercury & Pluto in libra and Neptune in sag. Makes venus the boomerang yod

    All confusing to piece together

    • Sure is Richy, Just take it step by step when working on a yod. Start at fully understanding your Mercury Pluto conjunction then the sextile. End up finally at Venus which is where you express all those intense emotions. How you love yourself and others.

    • That’s an interesting one Melissa. I wold expect very caring and loyal and, given the description for Mars perhaps some kinkiness, not sure about that though. Would be good for you to come back at some stage and give some feedback.

      • Thanks for the input. Caring and loyal, yes. Kinkiness, not so, perhaps because of my generation. I was born 9/10/1946 at 9:20 a.m. in Ashtabula, Ohio. Been married six times so I do have trouble maintaining a relationship. Guess I was born too independent. Have a great day.

  3. This must be my sun star, as my sun in Scorpio is just about in orb to this star. Izar seems to be out of orb. I was starting to think that I didn’t have a sun star. With the rate of precession, it makes my sun approx 1.44 degrees Scorpio.

    • I’m very much into research – that’s why I usually go to bed late! I’m often up till late doing any kind of research that interests me. I’m also very protective – I don’t know if this star means that the individual is protective or/and protected. I’m protective over family, friends and animals. I would say that I’m studious, as I love learning and absorbing new knowledge. I have a need for mental stimulation. I haven’t got the patience to hang about in the company of a person who hasn’t got much to say. I think this star could also mean that the Princeps individual loves other people with a profound and interesting/knowledgeable mind. Like attracts like.

    • Yes this star is within orb. To correct for precession you just need to add 0°10′ to your planets.

  4. I have a peregrine Mars conjunct Princeps and sex is a form of emotional and spiritual intimacy with another in my eyes. The above description reminds me of a scene from the exorcist movie, it does not seem to be a description that I can relate to. Maybe sex is a symbolism, possibly for another meaning?

    • Good to hear from you about this interpretation. I’m sure other with Mars hear will welcome it too. The more comments the better because it is rare that authors actually have these conjunctions themselves.
