Having completed work on "Ulysses", Joyce was so exhausted that he did not write a line of prose for a year. On 10 March 1923 he wrote a letter to his patron, Harriet Weaver: "Yesterday I wrote two pages—the first I have since the final "Yes" of "Ulysses". Having found a pen, with some difficulty I copied them out in a large handwriting on a double sheet of foolscap so that I could read them." This is the earliest reference to what would become "Finnegans Wake".
