When an author quotes another author in his novel, writes a poem in his book that he was reminded of when the events happened and that corresponds with what is happening in the text, what is that called? Is it a literary device? It can't be allusion.. I'm talking about where Che quotes a poem that he was reminded of when he left his loved one in the book The Motorcycle Diaries.

Scroll down and read the section called Single Quotation Marks.

I don't think this is a literary device, simply a punctuation issue.

Here are some websites that will help you identify literary devices:

The literary device you are referring to is called an epigraph. An epigraph is a quotation, phrase, or poem that appears at the beginning of a literary work, such as a novel, as a way to establish a theme, set the tone, or provide context for the story.

In the case of the book "The Motorcycle Diaries" by Che Guevara, the inclusion of a poem that Che was reminded of when he left his loved one is an example of using an epigraph. It serves as a way to enhance the reader's understanding of Che's emotions and experiences, while also connecting the events in the book to a larger literary or cultural context.

To find out more about literary devices such as epigraphs, you can refer to literary analysis books or websites, which often provide detailed explanations and examples of various literary techniques.
