on Writing Forward:
As we read poetry and other forms of literature, we’ll inevitably come across allusions. An allusion is a reference to something else; it can be indirect or explicit.
In poetry, most allusions refer to other works of art and literature or to historical persons or events. Cultural references are also common. Although allusion is a literary device, it’s often used in casual conversation and other forms of communication, expression, and the arts.
A quick reference can encapsulate a broad idea; therefore, an allusion allows us to make a deep and meaningful statement with just a few words.
