There is a stylistic device where you begin and end a text with the same metaphor.I'm sorry I don't have a "real-world" example in English, but I'll try to describe what I mean.
Let's say there's an article on software development. The article begins by likening the development process it to the construction of a car. Then it goes on talking about software, and in the last phrase it goes back to the car metaphor, achieving a "closure" effect.
Is there a proper name for this?
