I’d just like to mention that student writers love to use the verb “mention.” This writer mentions this and that writer mentions that.
But Herman Melville did not mention a white whale in his novel; he wrote a 704 page book about it. William Shakespeare did not mention the prince of Denmark; he wrote his longest play about this conflicted gentleman. Homer did not mention the Trojan war; he wrote a 15,693 line poem exploring only the later part of the conflict. Edward Gibbon did not mention the fall of the Roman Empire; he penned a six volume work on the subject. Obviously, these are extreme examples, but students do tend to use the verb a lot!
