Having done the longest day in literature with his monumental Ulysses (1922), James Joyce set himself an even greater challenge for his next book--the night. 'A nocturnal state. . . . That is what I want to convey - what goes on in a dream, during a dream.' The work, which would exhaust two decades of his life and the odd resources of some sixty languages, culminated with the 1939 publication of Joyce's final and most revolutionary work, 'Finnegans Wake'.
