Answer:
The repetition of the line, "Brennan on the moor/Brennan on the moor/bold and undaunted stood young Brennan on the moor"
Explanation:
The repetition of the line, "Brennan on the moor/Brennan on the moor/bold and undaunted stood young Brennan on the moor" in the opening and closing stanzas call the reader to remember the name of the man in this epic-style poem as we begin and end his tragic story.
In the opening lines, the repetition is quite like a battle cry where the person spoken about is seen as our hero. As readers, we repeat his name to honor him and call forth his story.
In the closing lines, the repetition is meant to be an homage to the hero of our poem who has died.
