Since I had my natal chart rectified several months ago, I've contemplated the deeper meaning of Mars in the fourth house--or more specifically, Mars in the third house conjunct the I.C. The interpretations I've read online often depict scenes domestic strife, even violence in the early home life. The relative harmony of my family life has made me question the accuracy of the rectified natal chart, although its other components describe my life beautifully.
Through introspection, intuition, and additional research, I believe I have identified subtler manifestations of this planetary placement. I regard the fourth house as a repository of feelings and emotions which develop throughout our formative years; the signs and planets contained therein may represent deeply-ingrained patterns of "learned behavior" which guide our actions.
Although astrologers often designate the twelfth house as the realm of the unconscious mind, this interpretation perplexes me because planets in this sector of a natal chart are above the horizon; they easily are visible, whereas planets in the fourth house are not. According to the Astrology Dictionary
, the Imum Coeli, or I.C., is the "lowest point in the sky (nadir) that a planet can travel relative to the horizon." Indeed, Imum Coel translates as "bottom of the heavens." In most house systems, the I.C. forms the cusp of the fourth house.
I believe Mars' position in the fourth house indicates that one's emotional foundation is based upon anger, although the individual may not entirely be cognizant of this influence. This foundation may originate as feelings of hostility or rage towards one's parents, which may or may not result from physical manifestations of parental violence or neglect. Instead, a child falsely may perceive its parents do not love them, or that they did not provide them with something necessary for the child's psychological or emotional development.
Please note that I approach this interpretation from the perspective of an Enneagram Type Four; it was the description of the tendencies and psychological motivations of this type which inspired me to write this post, for I connected several attributes of "parental orientation" with Mars' position in the fourth house. Obviously, other Enneagram types have this astrological placement, so their experiences may be different.
If you are not familiar with the Enneagram, please do not be deterred from contributing to this thread. I wish to learn about others' experiences with this Mars placement--particularly the subtle manifestations which I have described.
