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

“If ‘the world of imagination’ was ‘the world of eternity,’ as this doctrine implied, it was of less importance to know men and nature than to distinguish the beings and substances of imagination from those of a more perishable kind, created by the phantasy, in uninspired moments, out of memory and whim” [via]

Consider also:

  1. “A symbol is indeed the only possible expression of some invisible essence, a transparent lamp about a spiritual flame; while allegory is one of many possible representations of an embodied thing, or familiar principle, and belongs to fancy and not to imagination: the one is a revelation, the other an amusement.”
  2. “he finally escaped from ‘temptations and perturbations’ which sought to destroy ‘the imaginative power’ at ‘the hands of Venetian and Flemish Demons.'”
  3. “Inspiration was to see the permanent and characteristic in all forms, and if you had it not, you must needs imitate with a languid mind the things you saw or remembered, and so sink into the sleep of nature where all is soft and melting.”
  4. “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.”
  5. “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.”
