Authors use allusion as a literary device to refer to well-known literary, historical, or cultural texts to enhance their own work in various ways. By incorporating allusions, authors can create deeper layers of meaning, add complexity to their writing, establish connections with the audience familiar with the referenced texts, and evoke specific emotions or themes associated with the original works. Allusions can also serve as a form of homage, satire, criticism, or commentary on the referenced texts, allowing authors to engage in intertextual dialogue and enrich the overall reading experience for their audience.
