Listen! a frog
Jumping into the stillness
Of an ancient pond!
-- Matsuo Basho, Spring Days, 1686
This is the sort of thing that makes me despair of ever writing a decent haiku--a perfect, irreducible observation of nature.
Matsuo Basho was a Japanese poet in the 1600's and one of the first haiku masters. He is best known for his masterpiece, Oku no Hosomichi, or Narrow Road to the Interior, a chronicle of a five month journey through Japan told in a combination of haiku and prose.
There is a lovely article about Basho by novelist Howard Norman along with some beautiful photos taken along the route of Basho's journey in the latest issue of National Geographic magazine. You can read the article, view the photos, and even read a travelogue of Howard Norman's trip retracing Basho's steps on NationalGeographic.com
