Analyzes and discusses the craftsmanship of the poet and the elements of poetry. With the use of many examples the author reveals the poet's interpretation of human existence.
I got a beat-up little paperback copy of this book decades ago, handed down from my maternal grandfather (I think). I found the book so insightful & helpful in terms of understanding & appreciating many of the great works of poetry, both classical & modern.
I've been re-reading it now in 2019. The original copy was falling apart, literally page by page, so I bought a secondhand library copy to replace it. It's still one of the best books about poetry that I've ever seen.
Published in 1959, so not exactly modern, but a very good and complete series of essays about just about every aspect of poetry in the English language, accompanied by many poems, and very fun to read.
