What is the purpose of using an allusion in a literary context?

Using an allusion in a literary context serves to reference a significant idea, event, person, or work that carries deeper meaning and enriches the text. This technique relies on the reader's familiarity with the reference to enhance understanding and add layers of significance to the narrative or message. By invoking well-known themes, characters, or historical events, the author can create connections that resonate on a cultural or emotional level, allowing for a more nuanced interpretation of the text. This function of allusion contributes to the depth of literary works, as it not only complements the current narrative but also invites readers to engage with broader concepts and context, aiding in the overall understanding of the work.
