Joyce returned to Trieste in March 1907, but was unable to find full-time work. He went back to being an English instructor, working part-time for Berlitz and giving private lessons.[168] The author Ettore Schmitz, better known by pen name Italo Svevo, was one of his students. Svevo was a Catholic of Jewish origin who became one of the models for Leopold Bloom.[169] Joyce learned much of what he knew about Judaism from him.[170] The two became lasting friends and mutual critics.[171] Svevo supported Joyce's identity as an author, helping him work through his writer's block with A Portrait of the Artist as a Young Man.[172] Roberto Prezioso, editor of the Italian newspaper Piccolo della Sera, was another of Joyce's students. He helped Joyce financially by commissioning him to write for the newspaper. Joyce quickly produced three articles aimed toward the Italian irredentists in Trieste. He indirectly paralleled their desire for independence from Austria-Hungary with the struggle against British rule in Ireland.[173] Joyce earned additional money by giving a series of lectures at Trieste's Università Popolare on Ireland and the arts,[174] as well as on William Shakespeare's play Hamlet.[175]
