The base of all artistic genius is the power of conceiving humanity in a new, striking, rejoicing way, of putting a happy world ofits own creation in place of the meaner world of common days, of generating around itself an atmosphere with a novel power of refraction, selecting, transforming, recombining the images it transmits, according to the choice of the imaginative intellect. In exercising this power, painting and poetry have a choice of subject almost unlimited.
