Chris Edwards’s O Sonata dwells in the vortex of the underworld, plumbing the depths of the Orpheus and Eurydice myth and resetting the entrails of Rilke’s Sonnette an Orpheus into a crossword puzzle ready for consumption. In the eponymous sequence, Edwards offers up a renewal of the Orpheus (also known as ‘the futile male’) myth to signal his reconsideration of repetition and originality as the basis of a literary revision – releasing a suite of renditions that purposely misinterpret, transliterate and obscure.
