Picked this one up from Todd Swift's Eyewear blogzine eyewear, about a very early Sylvia Plath poem called 'Ennui'.
There's an introduction to, history and links to the poem itself here in an ezine called Blackbird.
When I read it I thought straight away of T.S. Eliot's 'Portrait of a Lady', from his first collection Prufrock and other Observations, which according to our course work, had some basis in the Henry James' novel of the same name, and a basis in Eliot's former US life.
The intro on Blackbird links the poem to Plath's reading of The Great Gatsby and explains the other allusions as well. What I find quite amazing, is the density of imagistic compression, with flashes of what becomes her later trademark voice.
