I picked up a great book in the library the other day. A Kick in the Head – An Everyday Guide to Poetic Forms is a children’s book describing and illustrating about 30 poetic forms. It includes obvious ones like the limerick, haiku, sonnet and couplet, but there were several that I hadn’t encountered before. I especially appreciate the forms with very rigid constraints, such as the villanelle, the triolet and the very tricky pantoum.
A few days later, I read an article by Michael Hofmann in the London Review of Books about the “professional controversialist and Austropathic ranter” Thomas Bernhard. Hofmann quoted a passage and said it “loops like a villanelle”. (The passage, a powerful yet demented diatribe, makes me want to read the book.) Encountering villanelles twice within a few days inspired me to write one. Very restrictive forms are easier to write in a way, since there are fewer choices to make.
