I've rebought the Herrick Complete Poetry, a book I owned in high school and lost track of at some point. It contains more than a thousand poems, many of them very short, over the stretch more than 500 pages. Did I read the entire thing when I was 15? It is very likely.
It is likely that I assimilated vast amounts of knowledge from this poetry, of conventions and tropes, genres and subgenres. In the brevity and variety of the poems there is an encyclopedic quality: foods, flowers, articles of clothing, rituals and folk beliefs, customs, political attitudes, mythological tropes, metrical forms. There are metaphysical conceits, but they aren't Donne-like.
The easy shifts from sacred to profane are most enjoyable, and from pagan myths to conventional Christian devotion.
