A literary reference is a mention or allusion to a well-known work of literature, author, character, or theme within a text. This technique enriches the writing by creating connections and adding depth, allowing readers to draw on their own knowledge and experiences. For example, referencing Shakespeare can evoke themes of love, betrayal, or tragedy. Writers often use literary references to enhance their storytelling or to convey complex ideas succinctly. By invoking familiar texts, they can create a shared understanding with their audience. This can include references to classic works like Homer's Iliad or modern literature, making the text more relatable and engaging.
