While it's based on the Odyssey by Homer (which is itself a story of a journey home), Joyce creates his own fictional characters and situations.
The main character, Leopold Bloom, is a fictionalized version of Homer's Odysseus. The setting, Dublin, is real, but the events and characters are imagined by Joyce.
Here's why people might ask this question:
* Realistic Detail: Joyce uses a stream-of-consciousness style and realistic details about Dublin, which can make it seem like a true story.
* Real People: Some of the characters in Ulysses are based on real people Joyce knew.
* Controversy: Joyce's novel was controversial because it used explicit language and dealt with taboo subjects. This controversy may have led some to question its truthfulness.
But ultimately, Ulysses is a powerful piece of fiction that explores themes of identity, memory, and the human condition through the lens of a single day in the life of Leopold Bloom.
