Premise: This schema for the novel "Ulysses" was produced by its author, James Joyce, in 1921 to help his friend, Stuart Gilbert, understand the fundamental structure of the book. Gilbert published it in 1930 in his book, "James Joyce's "Ulysses": A Study". The original copy of the Gilbert schema is housed in the Harley K. Croessmann Collection of James Joyce at Southern Illinois University Carbondale.
Hypothesis: Gilbert published the schema more than 100 years ago.
