"Ulysses" follows the thoughts and experiences of Leopold Bloom, a Jewish advertising canvasser, as he traverses Dublin on June 16, 1904. It's considered one of the most important and influential works of 20th-century literature, known for its complex stream-of-consciousness style and its exploration of themes like identity, memory, and the human condition.
While there are many other works of literature set in Dublin, "Ulysses" is arguably the most famous for its comprehensive and intimate portrayal of a single day in the city.
