Explanation:
An epic simile is a type of metaphor that uses comparisons to describe an event, someone, a place, etc. by using the words "like", "as" or "as in", and that is developed over several lines of verse, thus it is long, and which it's more commonly found in epic poems.
Therefore, the chosen lines are an example of an epic simile, as the narrator compares the character to "the tired ploughman" and, in the folowing lines, the narrator provides further characteristics of him.
