Midheaven in Cancer
You are a careful person, and you wait for the right time before you take action, but then, nothing can prevent you from implementing your project, which is often related with real estate matters or with the past. Unless particularly salient factors of your natal chart indicate otherwise, owing to your need for protection and your worry-prone nature, it is quite unlikely that you play a prominent role early in life. Cancer people are quite versatile. Thanks to their need for security, they are very likely to be successful in many different professions, such as those of hotelier and restaurant mentioned above, but also real estate agent, notary public, corporate manager, accountant, actor, sailor, diver, historian, antiquarian, social worker, wood-worker specialised in fine furniture, musician, or poet.

In a matter of minutes, you can get at your email address your astrological portrait (approximately 32 pages), a much more comprehensive report than this portrait of Ramón Menéndez Pidal.
Astrological Dominants of Ramón Menéndez Pidal
This section presents the main astrological dominants in Ramón Menéndez Pidal's birth chart. When the time of birth is unknown, four dominant factors are displayed: elements (Fire, Earth, Air, Water), modalities or modes (Cardinal, Fixed, Mutable), dominant planets, and dominant signs.
If the birth time is known, three additional dominants are included: dominant houses, house accentuations (angular, succedent, cadent), and quadrant distribution, which offers insight into psychological orientation and behavioral tendencies.
These astrological dominants form a kind of background tone a first impression of temperament and chart structure. They provide useful context ahead of the more detailed interpretation based on planetary positions by sign, house, aspect, and dignity.
Astrological Quadrants for Ramón Menéndez Pidal
Each quadrant is a combination of the four hemispheres of your birth chart and relates to a character typology. The Southern hemisphere the top of your chart, around the Midheaven is associated with extraversion, action, and public life, whereas the Northern hemisphere prompts to introversion, reflexion, and private life. The Eastern hemisphere the left part, around the Ascendant is linked to your ego and your willpower, whereas the Western hemisphere indicates how other people influence you, and how flexible you are when you make a decision.
Ramón Menéndez Pidal, the nocturnal North-western quadrant, consisting of the 4th, 5th and 6th houses, prevails in your chart: this sector favours creativity, conception and some sort of specialization or training, with helpfulness and relations as strong components. You need others' cooperation in order to work properly, although you are not very expansive: creating, innovating and thinking are what matter most to you because this self-expression enriches you and totally satisfies you.
Elements, Modes and House Accentuations for Ramón Menéndez Pidal
Ramón Menéndez Pidal, here are the graphs of your Elements and Modes, based on planets' position and angles in the twelve signs:
The predominance of Water signs indicates high sensitivity and elevation through feelings, Ramón Menéndez Pidal. Your heart and your emotions are your driving forces, and you can't do anything on Earth if you don't feel a strong affective charge (as a matter of fact, the word "feeling" is essential in your psychology). You need to love in order to understand, and to feel in order to take action, which causes a certain vulnerability which you should fight against.
Ramón Menéndez Pidal, Fire is dominant in your natal chart and endows you with intuition, energy, courage, self-confidence, and enthusiasm! You are inclined to be passionate, you assert your willpower, you move forward, and come hell or high water, you achieve your dreams and your goals. The relative weakness of this element is the difficulty to step back or a kind of boldness that may prompt you to do foolish things.
Earth qualities are under-represented in your chart, with only 1.32% instead of the average 25%. Deficiency in Earth may indicate that you have no interest in material and concrete values. It is likely that you live too much in your heart or in your mind, or even in your enthusiasm! The fact remains that you may end up in tricky situations, due to your lack of good sense or forethought: material life is unavoidable even if you are rather idealistic, dreamy, or easily content. You must tackle concrete life necessities, for fear of... being forced to cope with them, later, in much more unpleasant ways!
The twelve zodiacal signs are split up into three groups or modes, called quadruplicities, a learned word meaning only that these three groups include four signs. The Cardinal, Fixed and Mutable modes are more or less represented in your natal chart, depending on planets' positions and importance, and on angles in the twelve signs.
Ramón Menéndez Pidal, the Cardinal mode is dominant here and indicates a predisposition to action, and more exactly, to impulsion and to undertake: you are very keen to implement the plans you have in mind, to get things going and to create them. This is the most important aspect that inspires enthusiasm and adrenalin in you, without which you can grow weary rapidly. You are individualistic (maybe too much?) and assertive. You let others strengthen and improve the constructions which you built with fervour.
Houses are split up into three groups: angular, succedent and cadent.
The first ones are the most important ones, the most "noticeable" and energetic houses. They are the 1st, 4th, 7th and 10th houses. Their cuspides correspond to four famous angles: Ascendant for the 1st house, Imum Coeli for the 4th house, Descendant, opposite the Ascendant, for the 7th house and Midheaven for the 10th house, opposite the Imum Coeli.
Planets are evaluated according to a whole set of criteria that includes comprehensive Western astrology rules. At their turn, planets emphasize specific types of houses, signs, repartitions etc., as previously explained.
Cadent houses, namely the 3rd, 6th, 9th and 12th houses, are very emphasized in your chart, Ramón Menéndez Pidal. They indicate important potential for communication, adaptability and flexibility. These houses are symbolically linked to the mind and intellect. The relative weakness implied by these characteristics indicates your tendency to hesitate or to be indecisive, but also your remarkable ability to start off again, which is a nice quality, finally: you can easily get yourself out of a tight spot thanks to your mobility and casualness, in the best sense of the term. This group of houses corresponds to evolutionary characteristics of your personality. However, they are only indications and you must include them in the rest of your chart in order to see whether they are validated or not!
Note: this dominant is a minor one.
Dominants: Planets, Signs and Houses for Ramón Menéndez Pidal
In astrology, planets symbolize core drives, signs shape how they express themselves, and houses show where they manifest in life. A dominant planet points to a strong inner dynamic, a dominant sign reflects prevailing temperament, and a dominant house highlights key life priorities.
This triad or duo when the birth time is unknown offers a broad overview of personality before deeper interpretation through aspects and dignities. It serves as a prelude to more detailed chart analysis.
In your natal chart, Ramón Menéndez Pidal, the ten main planets are distributed as follows:
The three most important planets in your chart are Neptune, Jupiter and Uranus.
With Neptune as one of your three dominant planets, you are a secretive and ambiguous person, often confused or unclear about your own motivations! Indeed, you are endowed with unlimited imagination and inspiration, as well as with an extreme sensibility that may turn you into a psychic or a clairvoyant. On the other hand, your impressionability is such that you may have difficulties in separating what is concrete and solid from illusions or dreams.
A mystic, a visionary or a poet, you daydream, like any Neptunian, and you see what few people only can see, all of this being shrouded in aesthetic mists when you are fired with enthusiasm.
A boundless, infinity-loving man like you is inevitably likely to be more vulnerable and easily hurt because of your acute perception of events. In such cases, you are hit full in the face, and you may sink into gloomy daydreamings and dark melancholy.
That said, this mysterious aura definitely gives you an indefinable charm in the eyes of your close friends who are often fascinated by your unique ability to feel and to see what ordinary people can never see!
Jupiter, the planet of expansion, organization, power and benevolence, is quite emphasized in your chart. Like any Jupiterian, you are warm, open, sociable, consensual, active and optimistic. You can use your self-confidence to erase differences of opinion, and you leave the task of analyzing and perfecting things to specialists. Your role, and you know it since you were young, is to gather, to demonstrate your synthesizing and conciliatory mind, and to naturally reap its fruits - power.
You appreciate legality, social order but also order in general. With you as a leader, every plan or human entity can be organized and structured. You excel at supervising. The Jupiterian type is indeed the politician par excellence, and a positive Jupiter in your chart is synonymous with good integration into society, whatever the chosen path.
Is this idyllic picture really perfect? Certainly not: each planet's typology has its own weaknesses. One of yours is pride, like the Solarian, but your will of expansion at all costs may generate a form of exaggeration in everything, endless pleasure, inappropriate self-confidence that could lead you to rough materialism and the thirst for absurd material comfort - in the worst cases, of course.
Uranus is among your dominant planets: just like Neptune and Pluto, Uranian typology is less clearly defined than the so-called classical seven planets that are visible to the naked eye, from the Sun to Saturn. However, it is possible to associate your Uranian nature with a few clear characteristics: Uranus rhymes with independence, freedom, originality, or even rebelliousness and marginality, when things go wrong...
Uranus is Mercury's higher octave and as such, he borrows some of its traits of character; namely, a tendency to intellectualize situations and emotions with affective detachment, or at least jagged affectivity.
Therefore, you are certainly a passionate man who is on the lookout for any kind of action or revolutionary idea, and you are keen on new things. Uranians are never predictable, and it is especially when they are believed to be stable and well settled that... they change everything - their life, partner, and job! In fact, you are allergic to any kind of routine, although avoiding it must give way to many risks.
In your natal chart, the three most important signs - according to criteria mentioned above - are in decreasing order of strength Pisces, Aries and Cancer. In general, these signs are important because your Ascendant or your Sun is located there. But this is not always the case: there may be a cluster of planets, or a planet may be near an angle other than the Midheaven or Ascendant. It may also be because two or three planets are considered to be very active because they form numerous aspects from these signs.
Thus, you display some of the three signs' characteristics, a bit like a superposition of features on the rest of your chart, and it is all the more so if the sign is emphasized.
Pisces is among your dominant signs and endows your personality with unlimited sources of emotions, dreams, imagination, and sensitivity, to the extent that you literally swim in a cloudy ocean of delightful impressions. These impressions are so intense and overwhelming that you don't really need to take action concretely, to show your dynamism or your willpower, since you already live so intensely with your feelings - you are as keen as a radar, always on the alert! That is why some people may not like your carelessness, and the lack of clarity in your opinions or actions; however they quickly notice your artistic talents, your poetic or artistic side, and your total lack of wickedness. Besides, you feel compassion for people in pain - empathy is one of your great qualities. Thanks to your flexibility, your intuition, and your generosity, you may spend an important part of your life helping others. And if you are creative or if you have well-known artistic talents, everybody will forgive your little flaws: absent-mindedness, lack of energy or of will, too dreamy temperament...
Arian blood runs through your veins! You have that enthusiasm, frankness, courage, and fastness which usually make you so likeable in spite of your somewhat rough, naive, or violent side. As a bonus, Aries' gushing fire always gives you the impetus to make a fresh start, should you stumble or undergo life hardship!
Cancer is one of your dominant signs and endows you with imagination and exceptionally shrewd sensitivity. Although suspicious at first sight - and even at second...- as soon as you get familiar with people and let them win your confidence, your golden heart eventually shows up, despite your discretion and your desire for security that make you return into your shell at the slightest alert! Actually, you are a poet and if you are sometimes blamed for your nostalgia and your laziness, it is because your intense inner life is at full throttle...
The 7th, 6th and 5th houses are the most prominent ones in your birth chart. From the analysis of the most tenanted houses, the astrologer identifies your most significant fields or spheres of activity. They deal with what you are experiencing - or what you will be brought to experience one day - or they deal with your inner motivations.
Your 7th house is one of your dominant houses: it symbolizes other people, marriages, associations, contracts, and partnerships. Your personal achievement and maybe your problems - depending on the rest of your chart - are mainly influenced by your rapports with others, the area in which you tend to commit yourself a lot. You appreciate communication, and you give importance to others' opinions. Success requires the support of others, which seems obvious and natural to you. Your marriage generally contributes to your fulfilment.
Your 6th house is quite emphasized and indicates interest in work and daily occupations that take up a lot of your time: in analogy with Virgo, this house inclines towards perfectionism and training; somehow, you may be fulfilled through the process of being useful and investing your energy in your work. An environment appealing to you may be involved - your colleagues, for example - or a passion for one of these daily occupations. Medical positions or pets may play a role in your life; or ancillary love affairs too... These are a few possibilities indicated by an important 6th house.
The 5th house is one of your dominant houses: hobbies, love life, sports, and games, including speculation and all kinds of entertainment, are fields that you actually take seriously! On a more subtle level, artistic creation as well as other forms of creation - including begetting children - could be one of your assets. You gain from taking part in leisure associations and various activity clubs in which a catchword resounds more than for most people: pleasure.
After this paragraph about dominant planets, of Ramón Menéndez Pidal, here are the character traits that you must read more carefully than the previous texts since they are very specific: the texts about dominant planets only give background information about the personality and remain quite general: they emphasize or, on the contrary, mitigate different particularities or facets of a personality. A human being is a complex whole and only bodies of texts can attempt to successfully figure out all the finer points.
The Moon in Pisces and in House 6: his sensitivity
Your sensitivity is all on edge, Ramón Menéndez Pidal, and your emotions so deep, your imagination, so lively, that you are often found in the sweet realm of dreams. You create your own fantastical world with entangled fragments of current reality, romantic souvenirs and hidden hopes. Your receptiveness is so intense that it may border on mediumship or, more disturbing and rare, you may have hallucinations. Your character fluctuates according to the stimulation of the moment but in general, you are a nice person, full of gentleness and romanticism, always ready to understand and to dedicate yourself. You have real healing powers, would it be only through your ability to instinctively understand other people's sufferings. Your affective structures can be likened to a roving radar. You are vulnerable, hurt by the slightest aggression and easily influenced because you are unable to step back from people and events; therefore, you may start to be doubtful and lose the self-confidence that you so badly need to progress.
Ramón Menéndez Pidal, it is likely that you are popular in your work environment, and you may even be considered to be some kind of star by your colleagues. Or, if it is not the case, you have a clear tendency to react emotionally, very quickly and strongly... (excerpt)
The Ascendant is in Libra and the ruler of the Ascendant is Venus, in Pisces: his behaviour
Psychologically speaking, your nature is sanguine and communicative or nervous and introverted, depending on who prevails, either Venus, the principle of harmony, extraversion, desire to seduce, easy and airy communication, or Saturn, the principle of rigour, introversion, self-control, concentration and meditation. Unless Saturn is very strong in the rest of the chart, Libra is very delicate and charming. She easily adjusts in society, particularly with her perpetual search of compromise. It is the reason why you may seem to be hesitant and weak. You do not dare to insist or to assert your views: you prefer to intervene as an agent for harmony, of rally and equity, even to the detriment of your self-assertion. You loathe violence and you strive with all your heart to pacify, to smooth things over, and to adjust to the situation with flexibility and grace.
Since you are born under this sign, you are sentimental, charming, courteous, delicate, refined, loyal, pacifist, fair, distinguished, light, romantic, cultured, airy, likeable, spruce, perfectionist, caring, gentle, quiet, tidy, social, artist, with strong aesthetic tastes, tolerant, lenient, sociable, seductive, elegant, kind, respectful, balanced, but you may also be hesitant, weak, wavering, selfish, fragile, indecisive, timid, indolent, cold or even insensitive.
In love, Sir, you cannot help but try to seduce wherever you go, and you succeed fairly well. You are a real heartbreaker and your natural gift borders on impertinence and injustice, from the outsiders point of view!
You are so likeable, easy to deal with, caring, smiling, diplomatic, you establish connections with such great ease, that you attract a majority of women, including those you are not interested in. It is not a game, it is your nature. Each and everyone believe to be the object and the target of your favours whereas, in fact, it is the way you behave with everybody.
You cannot stand solitude at all: you prefer to be ill-accompanied rather that to be alone. There is a danger that you remain attached to a person who does not suit you best. You are spoilt for choice. You should be able to find a suitable match and to reach the state of harmony that is the centre of your deep motivations.
You are a perfectionist, like Leos who are so demanding regarding the quality of their partners. Real life is seldom as beautiful as your ideal and you may be deceived and badly wounded if your couple should break down. But you will pursue the quest of your soul mate with all the natural qualities that are almost entirely dedicated to this search.
The ruler of the Ascendant, also referred to as the chart ruler, brings a few interesting nuances to the meanings provided by the Sun and the Ascendant. The sign in which the ruler of the Ascendant is posited fine-tunes the style of personality described by the Sun and the Ascendant. It may strengthen it if the sign is identical to either of them.
The ruler of your Ascendant is in the same sign as your Sun. This specific feature means that the Sun's characteristics in sign previously delineated are strengthened.
The Sun in Pisces and in House 6: his will and inner motivations
Psychologically speaking, your nature is adaptable and receptive, exactly the opposite of the sign of Virgo whose very essence is to analyze every detail, thus creating a definite duality between the self and the outside world: conversely, Pisces absorbs and erases all forms of differentiation they face. With Pisces, there is no opposition, no conflict and no individual reaction. There is only fusion, non-separation, a perpetual and mobile spreading of the self over some blurred and huge sensation of sympathy with the environment. It is the absolute reign of feelings and emotions over the intellect and its separative logics.
As you are born under this sign, you are emotional, sensitive, dedicated, adaptable, nice, wild, compassionate, romantic, imaginative, flexible, opportunist, intuitive, impossible to categorized, irrational, seductive, placid, secretive, introverted, pleasant, artistic, and charming. But you may also be indecisive, moody, passive, confused, wavering, lazy, scatterbrained, vulnerable, unpredictable and gullible.
In love, Sir, you are the very type of the sentimental romantic in the highest meaning of the term. You live your love affairs in your mind. You upkeep the weft of your endless daydreamings just to exacerbate your emotions and your feelings, over and over again.
You fall in love frequently and according to how your encounters develop. You adjust to the person you set your heart on and you may harbour illusions because your imagination and your capacity to intensely live a virtual life are very strong. You are utopian and you are so gentle that you usually achieve your aims in spite of your boundless passivity: you seldom take the first step, except when you are thrown a line, which is as big as a tree trunk
You live for love and through love. Your only weakness may be your lack of determination at the early stage of a relationship. However, once you get started, if there is any compatibility, you trap your prey with your overflowing affectivity and your unlimited sensuality.
Pisces waters are shifting and changeable. When other opportunities appeal to you, you are able to handle two relationships simultaneously. You achieve an alternate osmosis with your partners and you see no harm in doing so, because you live the instant with plasticity and in communion.
You loathe solitude and you prefer to be caught in the nets of a woman even though she does not match your personality. If, by lack of chance, your partner belongs to the domineering and unscrupulous type, you may be trapped and wake up bitter and disappointed that you extended for too long the illusion of a marvellous story.
Once you find your soul mate, your home is usually harmonious. In your couple, love is immense, even mystical. Like a wave, it bathes the shores of your emotions, which range from the noblest feelings to the wildest physical passions. Since you merely live in concrete life, it is necessary that your partner be well grounded, so that your home is well up kept and your children are properly reared!
You are a perfectionist, Ramón Menéndez Pidal. Your constant concern is to improve yourself in every regard, to amass knowledge, to become helpful and to be at the top of your performances and your competencies. Work is an important area and, contrarily to many others, you are comfortable... (excerpt)
