Okay. Sir Alec Guinness. If you’ve struggled with this poem, as I think we all have, an excellent way to approach it is by listening to a good reading. Guinness does a wonderful job. He brings out nuances not easily recognized when you are pushing through the poem by yourself.
There is a temptation to go too fast with this poem, to get it over with, when, instead, it should be savored slowly. Guinness reads at a pace that allows this. Even if it takes a half hour. (You can always come back to it.) If you have the text with you, read along. So much the better.
The numerous obscure references remain but there are books and YouTube videos to help you with that, too. But the lectures and analysis can wait. First, the reading.
