Explanation:</h2>
An allusion is a reference in a text to another well-known text, person, event, or thing. Here, the passage is referring to the ides of March, or Caesar's death. Julius Caesar's death is a very well-known event in history, so the ides of March is considered an allusion.
This is a cultural allusion because <em>ides </em>means the 15th of a month, but it also means a <em>bad omen </em>or a <em>threat</em>. This is a historical allusion because the ides of March is when Caesar was assassinated.
