If you haven’t noticed, literary devices are often just fancy words for simple concepts. A metaphor is literally a comparison and hyperbole is just an over-exaggeration. In this same style, allusion is just a fancy word for a literary reference; when a writer alludes to something, they are either directly or indirectly referring to another, commonly-known piece of art or literature.

The most frequently-alluded to work is probably the Bible. Many colloquial phrases and ideas stem from it, since many themes and images from the Bible present themselves in popular works, as well as throughout Western culture. Any of the following ideas, for example, are Biblical allusions:

Referring to a kind stranger as a Good Samaritan

Describing an ideal place as Edenic, or the Garden of Eden

Saying someone “turned the other cheek” when they were passive in the face of adversity

When something is described as lasting “40 days and 40 nights,” in reference to the flood of Noah’s Ark.

Of course, allusion literary devices aren’t just Biblical. You might describe a woman as being as beautiful as the Mona Lisa, or you might call a man as stoic as Hemingway.

Why write allusions? Allusions appeal to common experiences: They are metaphors in their own right, as we understand what it means to describe an ideal place as Edenic.

Like the other common literary devices, allusions are often metaphors, images, and/or hyperboles. And, like other literary devices, allusions also have their own sub-categories.

Allusion Writing Exercise

See how densely you can allude to other works and experiences in writing about something simple. Go completely outside of good taste and name-drop like crazy:

Allusions (way too much version): I wanted Nikes, not Adidas, because I want to be like Mike. But still, “a rose by any other name”—they’re just shoes, and “if the shoe fits, wear it.”

From this frenetic style of writing, trim back to something more tasteful:

Allusions (more tasteful version): I had wanted Nikes, not Adidas—but “if the shoe fits, wear it.”
