of a new nature

The nature poem. So inscribed, so written, so set into the tradition of poetry that it can look like an arcane code. But it is not arcane. In fact, the nature poem is volatile: an accurate register of cultural and historic change. Before the Industrial Revolution it was a pastoral poem; and after a pessimistic one. It has always been there, in the center of the action. Like other poetic conventions, it has its roots in deeply human things. Change those things, alter that angle, and the roots will shift, ready to be put somewhere else.

I believe Plath—the other Plath—changed the nature poem. She shifted its course. She re-directed its historic energy. Ariel may seem a slim text to argue with. Then again, many of the shape-changing texts of nature poetry—whether The Lyrical Ballads or North of Boston—are modest, apparently unimposing single volumes. Unimposing that is, until you read them.
