I looked at the charts of various famous paonters and found, itnerestingly, a number of them had a Saturn singleton - espeically ones that challenged the status quo. Uranus singeltons were also common, but not as common as Saturn ones.
Picasso, as I recall, had neither. He had a moon singleton.
I paint, although I don't think I've that great. I have teh desire, and so I do it. I kind liek the thought of doing something not because I can do it well, but simply because I can. I focus so much prefectionist energies on everything else I do that it's good that I have one activity to balance it out. I think my desire to paint comes from my Piscean/Neptunian energies in my chart.
Painting is a visual art and it requires an understanding of not just color and form, but media, texture, and various other elements that are intended to impact the audience through sight. With that in mind here's a few charts of my favorite painters:
Max Ernst had a Saturn singleton (only planet in personal houses), which empahized his Sautrnine nature as indicated by a Cap moon. Mars in taurus, combined with this Saturnine essence, sees to indicate Ernst's highly refined techniques and refined aesthetic, as well as his stubbornness and difficulty with authority (Ernst was his own authority). His Aries Sun and Gem Venus indicate his very dramatic, capriciousand (at times) mocking nature that was expressed in his art as well. Note also that Uranus is in the 5th - house of creativity - and its quincunxes his Venus. Ernst was part of both the Dadaists and Surrealists, two group that greatly challegned the staus quo.
Paul Klee has an Aries Saturn singelton (only cardinal planet) in teh 1st, along with Pisces moon rising conjunct Jupiter. Saturn also opposes Uranus in the 7th. A very intense 1st house. Although a quiter persona than Ernst, Klee liekwise challenged the staus quo. Note his Sag Mercury int he 9th near the MC - this squares his moon and trines his Saturn. He obviously felt the need to communicate, yet with a Pisces moon rising, he had to do so indirectly, iimaginatively, intutiively, even spiritually, as one can see in his surrealist art. Like many Piscean artists, Klee focused also more on imagination and transcendant meaning than techinique, even though he used a wide variety of techinque in very idiosyncratic ways.
Piet Mondrian is another Piscean painter who liekwise challenged convention to create art that was enfused to transcendant meaning and purpose. An intriguing thing about Mondrian's work, which is often ridiculed by critics as "soulless," is that he was that prefect Piscean: he drowned his own sense of ego to find his art. The piscean theme in his chart is emphasized by a crowded 1st house where Pisces is intercpeted and Moon and venus in the 12th. Techincally, his Pluto in Taurus is a singleton (only planet in a reactive or fixed house), which adds a Taurean influence to all that Piscean energy.
