Colour could give rise to sensations which would interfere with our [Braque & Picasso's, in the start of Cubism] conception of space. - Georges Braque

You put a blob of yellow here, and another at the further edge of the canvas: straight away a rapport is established between them. Colour acts in the way that music does, if you like.. .There is more sensitivity in technique than in the rest of the picture.

...when objects shattered into fragments appeared in my painting about 1909; this for me was a way of getting closest to the object.. .Fragmentation helped me to establish space and movement in space.

The only valid thing in art is that which cannot be explained. To explain away the mystery of a great painting – if such a feat were possible – would be irreparable harm.. .If there is no mystery then there is no 'poetry', the quality I value above all else in art. What do I mean by 'poetry'? It is to a painting what life is to man.. .For me it is a matter of harmony, of rapports, of rhythm and – most important for my own work – of 'metamorphosis'
