Jackson Pollock’s paintings are usually associated with the all over and drip paintings’ inventions during the mid-forties in New York. In fact, that’s the moment where his genius came to the most exciting period of his career. After years of struggling within, he finally “broke the ice” and started to reevaluate the plastic modern adventure. This dissertation is about Pollock’s paths, since the beginnings of the thirties until the black paintings, his last big period. At first, Pollock’s work seems complex and very contradictory, however, and that’s my point, if we see through this labyrinth a very coherent line lies underneath the appearance, in search for life and rhytms to his paintings. In Pollock’s case, it gains a special flavour for it deals with fundamental aspects of the modern alphabet. Jackson Pollock makes an assertion of the painting and paradoxically reveals an impasse that his own radical art generated.
