Henri Matisse Quote

Composition, the aim of which is expression, alters itself according to the surface to be covered. If I take a sheet of paper of given dimensions I will jot down a drawing which will have a necessary relation to its format – I would not repeat this drawing on another sheet of different dimensions, for instance on a rectangular sheet.... a drawing must have a power of expansion which can bring to life the space which surrounds it.
