Within the cubism of the years 1909-1912, Picasso adopted a “dark”, hermetic style in his works. These attest to his meeting with the artists and writers from intellectual circles, and particularly that of philosophical thought. Successively inspiring and inspired by cubism, Max Jacob, Gertrude Stein, Apollinaire, Alfred Jarry, and the writers associated with the journals La Voce and Leonardo (Ardengo Soffici, Giovanni Papini, and Giuseppe Prampolini) each played a determining role in the configuration of Picasso's new style. It was through these gatherings that the artist encountered Henri Bergson, the philosopher of duration.
