The world is not beautiful
I like William Blake pretty well. I had a book of his poems when I was younger and loved reading them. Too bad I don't think I've got it anymore. It was really a good selection and had some lovely illustrations to go with it. I was and still am in love with "The Tyger". Now I really want to go find a copy of that book.
Other than that most of the poetry I've read and enjoyed has been Greek and Roman. (Yay for majoring in the Classics!) The epic poems of course are quite enjoyable, but I also like some of the shorter poets like Catullus and Martial. I found Martial particularly amusing. They're some of the few books I hung onto from college.
I remember doing a unit on poetry in high school that really created a huge aversion to poetry for me. We covered poets like Byron, Shelley, and Frost but it seems like we covered their most boring poems. It's probably enjoyable for some people, but it was not up my alley and there was pretty much no variety in the curriculum. I was stuck with navel gazing and odes to flowers. I've since found a few poems I like by them. In particular I've fallen in love with Shelley's "Ozymandias".
Therefore it is.
