Ulysses is considered one of the greatest works of modernist literature and is noted for its innovative narrative structure, stream-of-consciousness writing style, and use of multiple literary techniques. The novel follows the lives of three main characters - Leopold Bloom, a Jewish advertising canvasser, Stephen Dedalus, a young writer, and Molly Bloom, Leopold's wife - as they navigate the streets of Dublin, Ireland on June 16, 1904, known as Bloomsday. The narrative switches between the perspectives of the three characters and covers a wide range of themes, including mortality, identity, love, and the meaning of life. Ulysses is widely regarded as one of the most challenging works of literature, but it is also highly rewarding, as it provides a unique and richly layered look into the human experience.
