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

“I was again enlightened with the light I enjoyed in my youth, and which had for exactly twenty years been closed from me, as by a door and window shutters…. Excuse my enthusiasm, or rather madness, for I am really drunk with intellectual vision whenever I take a pencil or graver in my hand, as I used to be in my youth.” [via]
