In art progress does not consist in extension, but in the knowledge of limits. - Georges Braque

I started to introduce letters into my pictures [his first collage art]. These were forms which could not be deformed, because, being two-dimensional, they existed outside three-dimensional space; their inclusion in a picture allowed a distinction to be made between objects which were situated in space and those which belonged outside space [the letters].

It is the limitation of means that determine style, gives rise to new forms and makes creativity possible.

Thanks to the oval I have discovered the meaning of the horizontal and the vertical.
