James Joyce’s Ulysses is a mock epic that parodies the Homeric epic Odyssey, therefore, not only its style is no longer grand, its content is also trivial. What is most striking is that its protagonist Leopold Bloom, the Irish Ulysses, compared with his prototype Odysseus, is a radical anti-hero, devoid of any heroic quality, but just an apparently most common man. But at the same time, he is also a most uncommon man not only because of his deviation from an epic hero but especially because of his great difference from the stereotypical Dubliners of his time. He is thus a heteroglossia among his fellow citizens and provides Joyce a critical perspective both to deconstruct the status quo of that time and to imagine a new future for his own nation.
