When Stuart Gilbert's fine study of first appeared in the United States, Joyce's work was banned. Now, over twenty years later, with Knopf's second edition of the commentary, it is available to the American public to peruse both the original and the commentary which will help to make a rewarding experience rather than a bewildering one merely an intellectual caper. The present edition has more material and more fully considered insights than the former one. It retains the form and general content of the older book, including illustrative sections of Mr. Gilbert, a great deal of whose work was done in contact with Joyce himself, says the object of the author was to present an aesthetic image of the world. He discussed techniques, themes, parallels used in the work, and then proceeds to a detailed analysis of the episodes that comprise Ulysses. The first four chapters, devoted to the ideas, themes, and parallels require especially close reading, as they give the general structure and content without the help of the chronological organization that aids in following the discussion of the episodes. Any reader of Ullysses will be glad to have this as a chart to help plot his course through the high and exciting seas of Joyce's work.
