This is a very clear introduction to the formal aspects of poetry, but it also serves as a reintroduction for someone who has an English Lit degree but never got very interested in the technical aspects of poetry.
We disagree on quite a few things — his characterisation of Anglo-Saxon poetry as “not English” (because of course, it is quintessentially English: the Anglo-Saxons became the English), for example, and his doubtfulness about Sir Gawain and the Green Knight (there are dialect words in Sir Gawain which survive still: just because Chaucer’s Middle English is closer to what became universal doesn’t mean Sir Gawain is irrelevant). Also his relative dismissiveness of tight forms like the villanelle: he rightly praises one of the most famous, Dylan Thomas’, but is otherwise fairly unimpressed by it. I love villanelles, and I think more people have “done them right” than he suggests.
Still, with short, easy-to-digest chapters, clear explanations, and a helpful glossary, not to mention the addition of his thoughts as a practitioner of the craft, this is an interesting and informative introduction to a cross-section of English poetry.
