When three or more planets occupy one sign, we generally call it a stellium. Naturally we expect the sign and the house where the stellium occurs to be emphatic in the person’s life. But the planet that is NOT included in the stellium may be equally significant as a “counter emphasis”, especially if its quality is dramatically different from the stellium sign.
Take the following horoscope of “Edmond” (born 04/12/1840 1:00AM in Lyon, France):
The impressive Aries stellium in the third house naturally suggests a tremendous need to be important, to be “Numero Uno” in his field. The exertion of force (Aries) will occur in the 3rd house of communication – we expect prolific professional communication, as Pluto ruling the Midheaven (career), Mars ruling the 3rd and Mercury (communication) are all located within the 3rd.
Here is the counter emphasis, though: the sensitive, vulnerable Venus in Pisces: it is undeniably emphasized by being in the Sun/Moon midpoint. What is such sensitive emotions doing behind all the bravado and ego assurance of Aries (with the Moon in Leo, no less)?
Additionally we see 4 quintile aspects, suggesting the need for creative outlet: could the Venus suggest arts, music? Then the incongruence is dissolved: this is a creative and energetic communicator dealing with a sensitive (Pisces) subject – music, to be exact!
The horoscope belongs to Edmond Audran, a French composer of internationally successful operettas. Venus in Pisces drives the stellium’s energy to communicate (compose) and be the important figure in his field.
