"But at my back I always hear Time's winged chariot hurrying near" illustrates a metaphor. A metaphor is a figure of speech in which a word or phrase is used to describe something by stating that it is something else.

This comparison creates a vivid mental image of time as something that is constantly moving forward and is rapidly approaching. The use of a metaphor helps to convey the idea that time is relentless and unstoppable, and that it is always moving closer to us. Therefore, the line serves as an example of a metaphor.
