Louise Bogan reads her poem in this montage by Josep Porcar for the Catalan website Blocs de Lletres. Porcar took the footage from another film on Vimeo: Mary, written and directed by Mel Eslyn. For the text of the poem, see here.
This video really adds to my appreciation of the William Blake poem. I’m not sure who put it together, but it’s one of a number of video poems from the Catalan literature site Blocs de Lletres (whence the Catalan subtitles).
