Suggestion: Compare and Contrast Seamus Heaney's 20th Century "Mid Term Break" with Ben Jonson's 17th Century "On My First Sonne". Both poems deal with the death of a young child and the themes of grief and regret. "Mid Term Break" is the perspective of a brother while "On My First Sonne" shows a father's grief.
