Sexton and Plath
"That Plath pilfered so heavily from one of Sexton's poems, albeit a minor one, is a bit of a revelation. Sexton believed Plath hid her 'real' influences. But Plath always wore her influences on her sleeve. Throughout her work, one can detect traces of her idols (Auden, Dylan Thomas, Roethke) as well as her friends and contemporaries (Sexton, Lowell, W.S. Merwin). And of course, quite prominently, Ted Hughes."
At least Plath's borrowing was for a worthy cause--"Daddy" is a wildly compelling piece of work.
My favorite Plath poem is the underrated "Blackberrying". The poem ends with the speaker on a sheep path that leads to a rocky orange cliff above the sea:
That looks out on nothing, nothing but a great space
Of white and pewter lights, and a din like silversmiths
Beating and beating at an intractable metal.
Are there any better closing lines in modern poetry? Some as good, perhaps. None better.
