William Blake and his Illustrations to The Divine Comedy in Ideas of Good and Evil by William Butler Yeats.

“Living in a time when technique and imagination are continually perfect and complete, because they no longer strive to bring fire from heaven, we forget how imperfect and incomplete they were in even the greatest masters” [via]

Consider also:

  1. “All in this great series are in some measure powerful and moving, and not, as it is customary to say of the work of Blake, because a flaming imagination pierces through a cloudy and indecisive technique, but because they have the only excellence possible in any art, a mastery over artistic expression.”
  2. “The technique of Blake was imperfect, incomplete, as is the technique of well-nigh all artists who have striven to bring fires from remote summits; but where his imagination is perfect and complete, his technique has a like perfection, a like completeness.”
  3. “In the illustrations of Purgatory there is a serene beauty, and one finds his Dante and Virgil climbing among the rough rocks under a cloudy sun, and in their sleep upon the smooth steps towards the summit, a placid, marmoreal, tender, starry rapture.”
  4. “Blake represented the shapes of beauty haunting our moments of inspiration: shapes held by most for the frailest of ephemera, but by him for a people older than the world, citizens of eternity, appearing and reappearing in the minds of artists and of poets, creating all we touch and see by casting distorted images of themselves upon ‘the vegetable glass of nature’; and because beings, none the less symbols, blossoms, as it were, growing from invisible immortal roots, hands, as it were, pointing the way into some divine labyrinth.”
  5. “This letter may have been the expression of a moment’s enthusiasm, but was more probably rooted in one of those intuitions of coming technical power which every creator feels, and learns to rely upon; for all his greatest work was done, and the principles of his art were formulated, after this date. Except a word here and there, his writings hitherto had not dealt with the principles of art except remotely and by implication; but now he wrote much upon them, and not in obscure symbolic verse, but in emphatic prose, and explicit if not very poetical rhyme.”
