I was looking for some sort of systematic way of getting down these subjective images and I had always admired, particularly admired the early Italian painters who proceeded the Renaissance and I very much liked some of the altarpieces in which there would be, for example the story of Christ told in a series of boxes.. .And it seemed to me this was a very rational method of conveying something. So I decided to try it. But I was not interested in telling, in giving something its chronological sequence. What I wanted to do was give something, to present what material I was interested in simultaneously so that you would get an instantaneous impact from it. So, I made boxes..
