"He Kandinsky had always expressed a great interest in abstraction when we visited Tunisia together in 1904. The Moslem interdiction of representational painting seemed to stir his imagination and that was when I first heard him say that objects disturbed him. Between 1907 and 1910 [the period in which Kandinsky painted his first abstract compositions], he began to rely increasingly on his own theories of art, which many of his friends could understand only with great difficulty."
