Reference should be made to examples of early printing, to the works of William Morris, and to the best modern printing.
XIII.—MORE THAN THREE VALUES
Line, Notan, Color—the elements by which the whole visible world is apprehended,—may or may not be used as the language of art. Like speech, this three-fold language may voice noble emotions in poetic style, or may subserve the vulgar and the humdrum. Art-language must be in art-form; a number of facts, or an incident, accurately described in paint and color may have no more connection with art than a similar set of written statements just plain prose. There is no art unless the statements are bound together in certain subtle relations which we call beauty. When beauty enters, the parts cease to have separate existence, but are melted together in a unit.
Advanced composition is only a working out of simple elements into more complex and difficult interrelations. If the picture has figures and landscape, the lines of each run in such directions, intersect and interweave in such ways as to form a musical movement. The tones and colors are arranged to enrich one another. A noble subject requires noble pictorial style.
