Blake and line

Blake's Exhibition and Catalogue of 1809 (E 550):

" The great and golden rule of art, as well as of life , is this: That the more distinct, sharp, and wirey the bounding line, the more perfect the work of art; and the less keen and sharp, the greater is the evidence of weak imitation, plagiarism, and bungling. Great inventors, in all ages, knew this: Protogenes and Apelles knew each other by this line. Rafael and Michael Angelo, and Albert Durer, are known by this and this alone. The want of this determinate and bounding form evidences the want of idea in the artist's mind, and the pretence of the plagiary in all its branches. How do we distinguish the oak from the beech, the horse from the ox, but by the bounding outline? How do we distinguish one face or countenance from another, but by the bounding line and its infinite inflexions and movements? What is it that builds a house and plants a garden, but the definite and determinate? What is it that distinguishes honesty from knavery, but the hard and wirey line of rectitude and certainty [P 65] in the actions and intentions. Leave out this line and you leave out life itself; all is chaos again, and the line of the almighty mus t be drawn out upon it before man or beast can exist.
