Machen's novella The Great God Pan is often cited as one of Lovecraft's most notable influences. In it, Dr. Raymond's ultimate goal is to devise a way to open the mind of man so that he may experience all the world has to offer. He calls this "seeing the great god Pan". After much study of the human mind, he devises an experiment that involves minor brain surgery. He performs this experiment on a young woman named Mary, but when she awakens she is terrified and mentally crippled.
