In the eleven years that Joyce spent in Trieste he matured as a man and as a writer too. He set up house and had family, he started struggling and publishing his first novels. It is in the cosmopolitan and irredentist ambient of Trieste, his second hometown, that he conceived the plot of "Ulysses" and composed "Giacomo Joyce". The latter is a prose poem, a "visualogue", made of fifty fragments, written with Joyce's best calligraphy in English, Italian, Triestine dialect and German. Set in Trieste it opens with an enigmatic question "Who?". The aim of this thesis is to investigate the mystery of the identity of the young girl of the text through the help of a psychoanalytic reading, a science that was developing in Trieste during Joyce's stay. The Irish writer was attracted by the method of psychoanalysis and, because of his daughter's sickness, met Fromm in person. He was extremely curious to explore the mechanism of the psyche and experiment it in his works.
