Nicolas Poussin quotes:

Color in painting lures the eyes as verses do in poetry.

Drawing is the skeleton of what you do and color is its flesh.

Colors in painting are as allurements for persuading the eyes, as the sweetness of meter is in poetry.

The purpose of art is delectation.

The idea of beauty does not descend into matter unless this is prepared as carefully as possible. This preparation consists of three things: arrangement, measure, and aspect or form.
